SPECIFICATIONS......................................................................................................................................17 3 OVERVIEW The ART CX310 Stereo 2-Way/ Mono 3-Way Active Crossover is a perfect addition to any sound reinforcement system. Designed for PA and fixed-installation applications, the CX310 employs 24dB/ octave state-variable, fourth-order, Linkwitz-Riley filters. These filters guarantee in-phase outputs at all frequencies. This ensures the proper acoustic summing of common signals from adjacent drivers in the crossover region. The CX310 may be used as either a stereo 2-way crossover network, splitting the signal in each channel into two separate frequency ranges (Lo and Hi), or as a mono 3-way crossover network, splitting one signal into three separate frequency ranges (Lo, Mid and Hi). Each channel features input level, high and low output level and crossover frequency rotary controls. A frequency x10 switch is provided for varying the crossover frequency from the standard 80Hz 920Hz to 800Hz - 9200Hz. Front-panel output mute switches are provided for each individual output to ease system setup. The rear panel features balanced XLR and 1/4” TRS input and output connectors as well as a 2-way/ 3-way mode selector switch. Power for the CX310 is internal. The ART CX310 Stereo 2-Way/ Mono 3-Way Active Crossover has the features and performance you need for any audio application requiring a crossover. Housed in a rugged all-steel chassis, the model CX310 will provide years of reliable and continuous service. Features • Stereo 2-way or mono 3-way configurations • Fourth-order Linkwitz-Riley filters • Balanced XLR and 1/4" TRS input and output connectors • Adjustable crossover frequency range (80Hz to 920Hz or 800Hz to 9.2kHz) • Independent output level control for each output • Individual output muting switches • Clipping indicators on all outputs • Rugged, fully shielded all-steel chassis • Internal AC power supply • Three year warranty 4 INSTALLATION The ART CX310 may be used in a wide variety of applications and environments. Enclosed in a 1U (1.75 inches high) rack-mountable, all-steel enclosure, the unit is designed for continuous professional use. The depth is 6.5 inches, exclusive of the power cord. Mounting location is not critical. However, for greater reliability, we recommend that you not place the unit on top of power amps or other sources of heat. AC POWER HOOKUP The CX310 has an internal power supply designed to operate from 105 to 120VAC at 50/60Hz. Export units are configured with a different power cord and the voltage switch is set for the country of destination. Before plugging the CX310 into the AC mains, make sure that all of the equipment following the crossover outputs are turned off or that all of the outputs are turned down. INPUT/OUTPUT CONNECTIONS The CX310 has XLR and 1/4" TRS phone jack connectors for each input and output. All connections are active balanced although the 1/4" phone jack connections can easily be converted to unbalanced operation by using two-conductor phone plugs. Inserting a plug into a 1/4" jack disconnects the associated XLR connector. MONO 3-WAY CONFIGURATION This information is intended to clarify how the CX310 is used in the mono 3-way configuration. Connections: Input Low Output Mid Output High Output Channel One INPUT (Channel Two INPUT not used) Channel One LOW OUTPUT Channel Two LOW OUTPUT Channel Two HIGH OUTPUT (Channel One HIGH OUTPUT not used) Controls: Input Level Low Output Mute Low Output Level Low/Mid Crossover Mid Output Mute Mid Output Level Mid/High Crossover High Output Mute High Output Level Channel One INPUT LEVEL control Channel One LOW MUTE switch Channel One LOW OUTPUT LEVEL control Channel One RANGE switch and FREQUENCY control (Channel One HIGH MUTE switch and HIGH OUTPUT LEVEL control not used) (Channel Two INPUT LEVEL control not used) Channel Two LOW MUTE switch Channel Two LOW OUTPUT LEVEL control Channel Two RANGE switch and FREQUENCY control Channel Two HIGH MUTE switch Channel Two HIGH OUTPUT LEVEL control 5 OPERATION FRONT PANEL CONTROLS POWER SWITCH The POWER switch applies and removes power to the unit. Make sure that all equipment after the CX310 is either off or the outputs are turned all the way down before turning the CX310 on or off. CLIP INDICATORS Separate HIGH and LOW CLIP indicators are provided for each channel of the CX310. These indicators will light at approximately 3dB before clipping occurs in any stage of the channel. To prevent overloading the channel, either turn down the CX310 input control or turn down the output level of the piece of equipment feeding the CX310 (i.e. mixer, equalizer or other piece of processing equipment.). INPUT LEVEL CONTROLS An INPUT LEVEL control is provided on each channel of the CX310. If you are using the CX310 as a mono 3-way crossover, the Channel One INPUT CONTROL is the only one used. The INPUT LEVEL control should be set at its 0 marking in most cases. Increasing or decreasing gain should only be done to make up for deficiencies in other parts of the system. MUTE SWITCHES MUTE switches are provided for each output on the CX310. These are intended for use when setting up your system and testing either the crossover frequency point or the separate amplifiers and speakers they are feeding. These switches allow you to isolate a specific frequency output on a specific channel for fine-tuning or troubleshooting. It is not recommended that you mute or un-mute any frequency band during normal usage. Levels should be turned down when the MUTE switches are activated or de-activated. LOW AND HIGH OUTPUT LEVEL CONTROLS Each channel of the CX310 has LOW and HIGH OUTPUT LEVEL controls. These controls are used to trim the output levels to the LOW and HIGH OUTPUT jacks on the rear of the unit, respectively. If you are using the CX310 as a mono 3-way crossover, the Channel One LOW OUTPUT LEVEL control sets the level of the LOW OUTPUT, the Channel Two LOW OUTPUT LEVEL control sets the level of the MID OUTPUT, and the Channel Two HIGH OUTPUT LEVEL control sets the level of the HIGH OUTPUT. 6 These controls attenuate only (there is no gain). In most cases you would set them to 0 (fully clockwise). You can use these controls to prevent overdriving the inputs of your amplifiers or to compensate for variations in amplifier gain or speaker efficiency. Additionally, you can use these controls to balance the level between highs and lows in your system. CROSSOVER FREQUENCY CONTROLS and RANGE SWITCHES Each channel of the CX310 has a crossover FREQUENCY control and RANGE switch to set the crossover point for the high and low frequencies. These controls cover the frequency range of 80Hz 920Hz, with the RANGE switch in the out position (x1), or 800Hz to 9.2kHz, with the RANGE switch in the in position (x10). All frequencies below the set frequency will be sent to the LOW OUTPUT and all frequencies above will be sent to the HIGH OUTPUT. When the CX310 is used as a stereo 2-way crossover, both RANGE switches will most commonly be used in the out position (80Hz-920Hz). When used as a mono 3-way crossover, the Channel One FREQUENCY control is used to set the Low/Mid frequency point and the Channel Two FREQUENCY control is used to set the Mid/High frequency point. In this case, the Channel One RANGE switch will most commonly be used in the out position (80Hz-920Hz), while the Channel Two RANGE switch will most commonly be used in the in position (800Hz-9.2kHz). The crossover filters are 4-pole Linkwitz-Riley designs (24dB/octave). This yields a sharp roll off to help protect speakers and the outputs sum to a flat response. NOTE: Never change the frequency range switches (from x1 to x10 position - or vice versa) with the crossover passing audio signals. This may produce transients that can damage speakers. REAR PANEL CONNECTORS and CONTROLS It is easy to interface the unit with a wide variety of equipment. The rear panel has balanced XLR and 1/4” phone jack connectors. XLR JACKS The XLR connections are balanced and follow the AES standard for wiring: Pin 1 = Ground, Pin 2 = Hot (+) and Pin 3 = Cold (-). These connectors directly parallel the associated 1/4” connectors. 1/4” PHONE JACKS The 1/4” connections are balanced with Tip = Hot (+), Ring = Cold (-), and Sleeve = Ground. A twoconductor (tip and sleeve) shorts the Cold (-) and Ground connections together to convert to unbalanced operation. Inserting a plug into a 1/4" jack disconnects the associated XLR connector. MONO/STEREO MODE SWITCH This switch configures the CX310 for stereo 2-way operation with the switch in the out position or for mono 3-way operation with the switch in the in position. 7 APPLICATIONS The following guidelines refer to a P.A. system, but the same basic ideas apply to a home recording setup or a Hi-Fi system. Typical Setup For a stereo 2-way system, separate high frequency (horn or tweeter) and low frequency (bass or subwoofer) speaker cabinets are used for each channel (left and right) of the stereo sound system and are driven by their own power amplifiers. For a mono 3-way system, separate high frequency (horn or tweeter), mid frequency (mid or full range) and low frequency (bass or subwoofer) cabinets are used for each channel of the sound system. The crossover is used to split each channel's signal into two or three frequency bands, which feed separate amplifiers. This delivers the proper frequencies to each speaker cabinet as well as allowing its associated amplifier to produce acoustic power more efficiently. Note: You will need two 310 crossovers if your three-way system is stereo. It is very important that you use caution when selecting the crossover points for any system. Refer to the documentation that came with your speaker cabinets for information on their proper frequency ranges. This is especially important for high frequency horns; damage may occur from sending lower frequencies than specified into the drivers! Signal Flow In most situations, the crossover is the last piece of equipment in the signal chain before the power amplifiers. Signal flow is as follows: Mixer → Equalizer → Crossover → Power Amplifier → Speaker Cabinets Sometimes a limiter is placed between the mixer outputs and the equalizer or after the equalizer for system protection. Initial Setup Tips 1. 2. 3. 4. 5. 6. 7. 8. 9. Set all level controls to their full counter-clockwise position. Connect the output(s) of your mixer (or equalizer) to the input(s) of the CX310. If stereo, Channel One is left. Connect the LOW OUTPUT of each channel (LOW OUTPUT of Channel One for mono 3-way configuration) to the power amplifier powering the low frequency cabinet(s). If set for mono 3-way, connect the MID output (LOW OUTPUT of Channel Two) to the power amplifier powering the mid frequency cabinet. Connect the HIGH OUTPUT of each channel (HIGH OUTPUT of Channel Two for mono 3-way configuration) to the power amplifier powering the high frequency cabinet(s). Set the crossover frequency for each channel (they should be the same if your PA cabinets are the same) or each frequency band for mono 3-way configuration. With the power amplifier volume controls turned all the way down, turn on all equipment in the system. With a program source running through the system, turn up the power amplifier volume controls and slowly turn up the crossover input level controls while checking for clipping. Turn up each of the crossover's output level controls while checking each individual output for sound and performance. 8 SERVICE PARTS PART # DESCRIPTION PART USAGE SWT DPDT LATCHING CON JACK 1/4" STEREO RSP POT 10KB RSP POT 50KX4 switches for low mute, range, high mute, mono/stereo input and output jacks level pots frequency pots 310-2003-101 MLD CAP SWITCH BLACK switch caps for low mute, range, high mute, mono/stereo 310-2004-101 310-2005-101 MLD CAP POT BLK,GREY CAP W/WHITE LINE CON FUSE 1/2 A 5X20MM SLO-BLO 100-5021-101 100-5225-102 310-2001-101 310-2002-101 341-2008-101 341-2009-101 310-2006-101 CON JACK XLR MALE CON JACK XLR FEMALE XFM POWER SUPPLY BOARD UPDATED 3102007101 3102008101 1005269104 DIG I.C.
