Do not operate a ICS-22 speaker panel near water, or place objects containing liquid on it. Do not expose a ICS-22 speaker panel to splashing or dripping water. Please read and follow these instructions before operating a ICS-22 speaker panel. (2) For proper ventilation, make sure ventilation openings are not blocked. Install the ICS-22 speaker panel according to the directions in the Installation chapter of this manual. (3) Do not install a ICS-22 speaker panel near a heat source such as a radiator, heat register, stove, or other apparatus (including amplifiers) that produces heat. Do not place naked flame sources such as candles on or near a ICS-22 speaker panel. (4) Only use attachments/accessories specified by Clear-Com Intercom Systems. (5) Unplug the ICS-22 speaker panel during lightning storms or when unused for long periods of time. (6) Refer all servicing to qualified service personnel. Servicing is required when: • The ICS-22 speaker panel has been damaged in any way. • Liquid has been spilled or objects have fallen into the ICS-22 speaker panel chassis. • The ICS-22 speaker panel has been exposed to rain or moisture. • The ICS-22 speaker panel does not operate normally. • The ICS-22 speaker panel has been dropped. Please familiarize yourself with the safety symbols in Figure 1. When you see these symbols on a ICS-22 speaker panel, they warn you of the potential danger of electric shock if the ICS-22 speaker panel is used improperly. They also refer you to important operating and maintenance instructions in the manual. Vitec Group Communications ICS-22 Speaker Panel Instruction Manual iii CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol alerts you to the presence of uninsulated dangerous voltage within the product's enclosure that might be of sufficient magnitude to constitute a risk of electric shock. Do not open the product's case. This symbol informs you that important operating and maintenance instructions are included in the literature accompanying this product. Figure 1: Safety Symbols iv Vitec Group Communications ICS-22 Speaker Panel Instruction Manual 1 OPERATION DESCRIPTION The Clear-Com ICS-22 is a two-channel speaker panel designed for use in theatres, live performances, industrial environments, and small television facilities. It features excellent speech intelligibility, even in high noise levels, and can be customized through its programmable options. • The ICS-22 is a two-channel speaker panel. • The panel must be powered locally. In addition, the ICS-22 contains a jack for an optional Clear-Com gooseneck panel microphone and a close-in, voice-operated circuit (VOX). This circuit allows automatic, alternate dipping of the panel microphone and the speaker in response to conversation. Selectable talking and/or listening allows the operator to communicate on two talk/listen paths. The dual-action talk button operates in electronic momentary or latching mode. Monitoring can be done through the headset, the integral speaker, or both simultaneously. The ICS-22 offers both visible and audible call signaling to attract the attention of operators. A balanced program input allows the monitoring of external audio using the headset or speaker. This program input can also be used as a paging function. The ICS-22 speaker panel accepts dynamic headsets, such as the Clear-Com PL-Pro™ Series HS-6 Telephone Handset, or PT-4 Push-to-Talk Hand Microphone. A sidetone control allows the operator to vary the level of his voice heard through the headset and speaker. • Users can install the panel in Clear-Com’s DT-Box. The integral speaker can be turned on or off by a convenient front-panel switch. An automatic speaker dipping circuit will lower the level of the speaker whenever the talk button is activated. The ICS-22’s close-in VOX dips the speaker or gooseneck microphone automatically as the panel is used. These features help minimize acoustical feedback. The ICS-22 will need to be powered locally. In permanent wall installations, a 16-VAC doorbell transformer will provide a convenient source of power. In DT-Box installations, a 14- to 18-VAC wall-mounted transformer will suffice. The connections to this transformer are made to the circuit board’s two-terminal, plug-on connector. The unit mounts either in a standard USA four-gang electrical outlet box or in an optional Clear-Com DT-Box. The extra thick front panel and compact, surface-mounted circuitry results in a reduced size and lighter weight package that maintains Clear-Com ruggedness. Vitec Group Communications ICS-22 Speaker Panel Instruction Manual 1-1 OPERATION Normal operation of the ICS-22 speaker panel only requires the front panel controls. For intercom operation, set the intercom level control to the desired level and press the talk button when talking. If a headset or handset is used, set the sidetone control for each channel for the desired amount of sidetone in the earphone. If the PT-4 hand-held, push-to-talk microphone is used, or if the panel microphone is used, set the sidetone controls for minimum feed-through to the speaker to prevent acoustic feedback. ECS System Configuration for ICS-22 Panels The Eclipse Configuration System (ECS) software does not directly support the ICS-22 speaker panel. In order to configure an ICS-22 panel the port is configured to drive an ICS-1008 panel with 14 keys (7 pairs of buttons). The two ICS-22 selectors are mapped onto the ICS-1008 keys starting from the left. Only the leftmost two pairs of keys on the ICS-1008 can be used to program the ICS-22; any other keys on the ICS-1008 will have no effect. There must be a corresponding listen key on the top row to the talk key on the bottom row of the ICS-1008 configuration for the ICS-22 panel to work correctly. If a talk key only is configured on the ICS-1008 in ECS the Talk key on the ICS-22 will not latch. It should be noted that the panel signalling and control protocol used by the Eclipse matrix differs from the Matrix Plus 3. As a result the operation of these panels with an Eclipse matrix may be slightly different to their operation with a Matrix Plus 3. 1-2 Vitec Group Communications ICS-22 Speaker Panel Instruction Manual FRONT PANEL • Appropriately setting the sidetone level decreases confusion, especially in loud environments. The controls, indicators, and connectors on the ICS-22 front panels are shown below and are described in the text that follows. A VOX Call Waiting B Talk/Listen Select Panel Mic Answer Back Intercom Level Headset Program Level Off Sidetone Talk On Speaker Figure 1-1: ICS-22 Front Panel Talk Button and Light • The talk button has five functions. This button transmits the headset or gooseneck microphone audio to the selected talk/listen panel/interface or the answer-back label. The talk button has a dual action (momentary or latching) depending upon how the button is pressed. The Talk button Latch/Non-Latching operation cannot be defeated in ECS even for latch disabled labels. The following describes the various functions of this button: • Momentary—Press and hold the talk button while speaking. Release it when finished. The light will be illuminated when the button is pressed. • Latching—Press and release the button quickly to latch the talk function. Press and release the button again to turn off the talk function. The light will be illuminated while the button is latched. • Talk indication—The associated talk light will illuminate green when the talk function is activated. • VOX indication—When the VOX feature is enabled, the talk light will illuminate green when the talk function is activated, but will turn red when the panel microphone is in use. This automatically dips the speaker volume. • Speaker dip—If the front-panel speaker is turned on and the VOX feature is not used, pressing the talk button will reduce the speaker output level to avoid feedback. Vitec Group Communications ICS-22 Speaker Panel Instruction Manual 1-3 • Note: The call-waiting light does not light when a call is received from a programmed label. Answer-Back Facility The answer-back facility answers calls from panels or interfaces that the panel has not currently selected. Call-Waiting Light This dual-function light: • is steadily lit when a call signal is received • flashes to indicate a call waiting signal, which has priority over a call signal. Answer-Back Button This three-function button: • sends a call signal to the selected, programmed label when the call waiting light is off • directs audio to the longest-waiting call in the call-waiting stack when the call waiting light is flashing • The panel’s answer-back feature offers a number of functions. • ends the current conversation from the call-waiting stack when the call waiting light is steadily on. Answer-Back Stack The answer-back stack tracks incoming calls from any label that is not assigned to the panel. These calls are available in the order they were received. The length of time the calls are available before they are automatically removed is set in the configuration program. Note: The label programmed to and selected by the panel will never appear in the answer-back stack and duplicate labels are never added. Answering a Call from the Answer-Back Stack To answer a call from the answer-back stack: 1. Press and release the answer-back button to select the longest waiting call. 2. Press the answer-back button while responding. The call waiting light will be on steadily. • A tone alert is provided to ensure call signals are noticed. Terminating Calls Answered with the Answer-Back Button To terminate a call answered with the answer-back button, turn off the call waiting light, and recover the previous call: • The receiving panel can terminate the call by pressing and releasing the answer-back button. • The calling panel can terminate the call. 1-4 Vitec Group Communications ICS-22 Speaker Panel Instruction Manual Answering Another Call from the Answer-Back Stack To answer another call from the answer-back stack: • Note: The configuration program can be set to also send an audible signal through the speaker, which can only be heard if the intercom level is turned up. • If the calling panel disconnected the call, the call waiting light will flash. • If the receiving panel disconnected the call, a call from another unselected label will be activated when the answer-back button is released. Sending a Call Signal The answer-back button can send call signals to a panel or interface currently on the selected talk/listen path when the call-waiting light is not on. The light will turn on when the button is pressed and turn off when it is released. Receiving a Call Signal The call waiting light turns on when another panel sends a call signal and remains on during the call. Tone Alerts Tone alerts are set through the configuration program. The panel has the following three tones: • A number of controls are available to adjust the panel’s audio levels. Tone Meaning Four rapid beeps Call signal Two beeps Label change Single beep Monitoring Table 1-1: ICS-22 Tone Alerts Intercom-Level Control • Note: Forcing the trimpots past their stop points will damage them. This control sets the listen level required on the speaker or headset. It does not affect the program-input level. Sidetone Control This knob adjusts the level of the operator’s voice that is heard while talking on the intercom. Setting a comfortable level of sidetone will ensure that the intercom line sounds alive and also helps modulate the operator’s voice relative to other voices on the line. Typically, different sidetone settings are needed depending upon whether the speaker is used. Turn the knob clockwise to increase the sidetone and counterclockwise to decrease it. Minimum sidetone is recommended when the speaker is used. Vitec Group Communications ICS-22 Speaker Panel Instruction Manual 1-5 Program-Level Control This control sets the program input audio level heard in the headset or panel speaker. Speaker ON/OFF Switch This switch turns the front-panel speaker on or off. It also controls whether the tone alert is heard through the speaker. The speaker volume will automatically dip when the talk function is set, unless the VOX function is enabled. Mic-Select Switch • The VOX feature provides operators with a voice activated option. This switch selects whether the panel microphone or the headset microphone is active. When the VOX feature is enabled, it is only operational when the panel microphone is active. Talk/Listen Select Switch This switch selects the panel/interface label (A or B) for communication. Headset Connector This connector is located on the front panel. All Clear-Com headsets are recommended for use with the ICS-22. The Clear-Com PT-4 Push-to-Talk Microphone or the HS-6 Telephone Handset will also plug into the headset connector. The following is a description of the characteristics of a suitable headset: • Mic Type—Dynamic; 150 to 400 ohms impedance; -55 dB output level. • Note: Do not connect Pins 1 and 3 together. Headset extension cords or headset “Y” cables are not recommended because they may increase crosstalk between channels. 1-6 • Headphone—Dynamic; 50 to 2000 ohms impedance. The wiring of the headset is to be as follows: Pin Number Description 1 2 3 4 Microphone ground (shield) Microphone hot Headphone ground Headphone hot Table 1-2: ICS-22 Headset Wiring The microphone and headphone wiring in the headset cord must be individually shielded. Vitec Group Communications ICS-22 Speaker Panel Instruction Manual Panel-Mic Connector • To install a GM-9 or GM-18 microphone there are four steps. Clear-Com recommends that the GM-9 (9-in. long) and GM-18 (18-in. long) plug-in panel microphones be used with the ICS-22. Both are the electret type. The 1/4-in. phone jack on the microphone mates with the panel-mic receptacle on the ICS-22’s front panel. To install a GM-9 or GM-18 microphone: 1. Remove the plastic plug from the jack, if present. 2. If a set screw is present in the microphone-mounting flange, check and unscrew it to make sure it is clear of the threads in the bushing. 3. Screw the microphone into the bushing and tighten. 4. Optional: Replace the set screw supplied with the gooseneck microphone on top of the microphone-mounting flange and turn it clockwise to lock the microphone in place. VOX Control • The VOX control is located to the right of the panel microphone connector and is recessed slightly into the front panel. When the panel microphone is selected on the ICS-22, the VOX control should be adjusted for proper operation. This control is located to the right of the panel microphone connector and is recessed slightly into the front panel. Use a narrow, flat-bladed screwdriver such as a “greenie” or “tweaker” for this adjustment. When the adjustment is correctly set, the talk lamp will be red when speaking into the panel microphone and will be green when hearing audio from the speaker. Turning the control clockwise makes the ICS-22 more sensitive. The VOX feature can be disabled by turning the VOX control fully counterclockwise. INTERNAL CONNECTIONS These controls are not to be adjusted on this panel, but are set as follows: Vitec Group Communications ICS-22 Speaker Panel Instruction Manual 1-7 POWER CONNECTION 4 5 PROGRAM INPUT • There are five internal connections. 3 MATRIX CONNECTOR VIEW FROM TOP OF ICS-22 321 • Option switches should not be changed from their factory settings. • Note: The ON position of each option switch is toward the circuit board and the OFF position is toward the front panel. The default position of the switches is the OFF position. FRONT PANEL CALL ALERT TONE LEVEL CONTROL 1 2 OPTION SWITCHES Figure 1-2: Internal Adjustments and Connections Call-Alert Tone-Level Control (1) This feature must be disabled by turning the control fully counterclockwise. Option Switches (2) The three option switches are set to the OFF position by the factory and should not be changed. Matrix Connector (3) This eight-wire modular jack (RJ-45) provides an audio and data communications link to the Matrix system. Program-Input Connector (4) A three-terminal, plug-on connector provides the program input to the panel. Program is fed to the headset and speaker. The level to the speaker or headset is controlled by the program-level control. The program-input connector accepts a balanced or unbalanced line-level audio signal from -20 dBu to +10 dBu. If this input is connected to the stage announce (SA) output of a main panel it can be used as a paging input. Since the level of this input is independently adjustable from the intercom audio volume, it can be used to override the intercom audio. 1-8 Vitec Group Communications ICS-22 Speaker Panel Instruction Manual The pinout of this connector is as follows: • The Program Input can be set between -20 dBu to +10 dBu. Pin Number Function 1 Ground (Shield) 2 Positive Signal 3 Negative Signal Table 1-3: ICS-22 XLR Pinout Information PIN 1 2 3 1 ICS-22 PROGRAM INPUT CONNECTOR XLR CONNECTOR Figure 1-3: ICS-22 Program-Input Cable Wiring • The panel can obtain power from three different sources. Power Connection (5) The panel requires local power, which can come from various sources, including: 16-VAC Doorbell Transformer • Note: Both 10-VAC and 16-VAC doorbell transformers are commonly available at hardware stores, but only the 16-VAC transformers are suitable in this case.The panel can obtain power from three different sources. A doorbell transformer can be attached to a separate box containing the power-line connection and the low-voltage, 16-VAC can be routed to the connector on the EB7-4W circuit board. This connection is especially useful if the headset or speaker panel is installed in a wall. 14-VAC Wall-Mounted Power Supply A Clear-Com wall-mounted power supply (part number 400008) can be used for powering the panel from 120 VAC. (Use part number 400011 for 220 VAC power.) This connection is a better choice if the headset or speaker is mounted in a desktop box, such as a Clear-Com DT-Box, which is not located on a wall. 24- to 28-VDC Source The headset or speaker panel can be powered from a DC source, such as batteries. To connect the selected power supply: 1. Connect the two wires from the power source to the two-position, plug-on terminal strip. 2. Plug this connector onto the circuit board as shown in Figure 1-2 on page 1-8.
