I. Introduction
The AES-302 Digital Audio System comprises of a two input AES compatible switcher, four output
digital audio DA and digital to analog converter. The unit also has status and diagnostic error indicators for
troubleshooting. The AES-302 is intended for use at unattended transmitter sites or for virtually any digital
switching, distribution and/or D/A conversion application. The unit has the capability to automatically
switch inputs upon detection of loss of clock, digital error flags and/or silence sense. In addition to these
features, the unit can function as an interface standards converter. As shipped from the factory the unit is
supplied with XLR balanced connectors. The unit can be configured with any combination of input/output
connectors if desired. Default factory supplied connections are XLR. Optical and S.P.D.I.F – RCA
connections are available as options.
II. Unpacking and Inspection
Carefully inspect the unit after unpacking and make certain that no damage has occurred during shipping.
If damage is noted, contact the shipper immediately and file a claim for damages. Each unit is carefully
packed and carries full insurance against damage. Inspect the packing list and make sure that the contents
of the package match those described on the packing list.
III. Installation and Connections
Select a space in suitable E.I.A. standard rack to locate the unit. Determine the local electrical power
supply voltage and select the proper input voltage at the rear of the unit. As supplied from the factory, your
AES-302 is setup for 120 V.A.C. 60 Hz unless noted otherwise. To change the input voltage to 240 volts,
simply slide the plastic cover and remove the p.c. board in the E.M.I. protected power entry module and
flip it so that “240 Volts” is legible from the rear as the board is placed back into the power entry module.
No replacement of the fuse is necessary as the fuse supplied is rated for up to 250 V.A.C. operation. The
unit is rated to run from 120/240 V.A.C. at 50 to 60 Hz operation. Make connections to the unit following
good engineering practice. Supply power to the unit utilizing a three pronged grounded outlet. Do no lift
the electrical ground to the unit at the power receptacle as this will result in a safety hazard. In the event of
ground loops, lift the ground at the offending connection only. Make certain that the unit is afforded proper
ventilation in the area of the top cover vent.
A. Digital Interface
Unless ordered as an option Inputs to the switcher are balanced XLR connectors conforming to the AES
standard. The unit may be ordered with SPDIF or optical interface. Each XLR connection is terminated at
110 ohms as per the standard. SPDIF inputs are terminated at 75 0hms. The balanced digital outputs are
also XLR connections, which provide 110-ohm transformer coupled source impedance as per the standard.
Again as an option outputs can be configured for SPDIF or optical interface.
B. Analog Interface
There is provided on the rear of the unit a left/right balanced analog output. This output is suitable for
driving 600-ohm balanced lines and is short circuit protected. A headphone jack and volume control
buttons are provided on the front panel of the unit for confidence monitoring of the incoming feed.
IV. Features and Operation
The AES-302 Digital Audio System is designed to select one of two AES3 compatible feeds and route it to
up to four balanced, optical or unbalanced digital loads. It also contains a high quality digital to analog
4
converter providing a balanced left and right output. The unit features a front panel headphone output and
volume control for easy confidence monitoring. The AES-302 can be used as a totally automatic switcher
sensing loss of clock or any error displayed on the front panel to command the switcher to select the
alternate feed. In addition to digital error switching, the unit features a silence sense circuit for switching
upon audio failure conditions. All automatic switching functions are user defined and can be initialized
with a simple DIP switch setting upon installation of the unit. Command of the switcher can also be
performed manually at the front panel or remotely.
Remote control of the unit is accessed through the rear panel 9 pin D connector. Simple momentary ground
closure to the appropriate pin selects channels and error reset. Status of channel selected and error flag is
also available at this connector. Refer to the pin out table 3 on page 6 for connection information. The
interface is compatible with open collector command. The AES-302 supplies +15 V.D.C. for powering
open collector actuators.
Two additional features that have been added to later production AES-302 units includes power fail feed
through of the selected input to AES output #1 and a delay circuit has been added to the automatic
switching function. With no power connected to the unit, the AES-302 will pass the last selected input
signal to the #1 AES output through K3 NC contacts. Upon power application K3 energizes and AES #1
output receives its signal from U2 RS-485 driver. The additional delay was added to prevent the unit from
switching on momentary glitches that can occur in STL equipment. An added 3 seconds to the switching
time prevents the unit from switching under transient conditions.
V. Initial Operating Set up
Attach input and output connections to the unit using the appropriate connector. The unit can be supplied
with XLR, S.P.D.I.F., or optical connectors at any of the inputs or outputs. If the connector scheme
supplied is not the one desired, consult the factory for a field or factory connector modification.
Plug the remote control plug in and tighten the connector screws in place.
You may select any or all of the error flag and/or silence sense switching, which will command the
switcher to switch to the alternate path. The “no lock” position S6-2 is always selected for automatic
operation. Other error flags and the silence sense error are selected by placing the designated DIP switches
to the on position. Refer to the theory of operation section table 1 on page 5 for possible settings. Once
this is done, the unit is ready to be powered up for operation. The default setting is to command the
switcher upon loss of clock. When the silence sense error is selected for switching, there are several
configurations possible. It is possible to monitor both left and right channels and switch upon complete
audio loss or to have the silence sensor switch upon loss of left or right channel individually. This feature
was added so that non correlated audio feeds can cause the silence sensor to switch where one feed may
take precedence over another. Selection of L+R, Left, or Right only audio is done by placing the proper
jumpers on the motherboard. Refer to the theory of operation section table 2 on page 5 for the various
settings.
Once power is applied and a valid AES bit stream is applied to the selected input, the unit will default to
“Manual” mode of operation. The LED indicator over the “Manual” button should be illuminated. In
addition, the channel selected LED indicator will be lit. There should also be an indication of sample
frequency. Press the error-reset button to clear any errors that might be indicated. If the digital audio stream
feeding the active channel of the unit is valid and no errors occur the unit is ready for to be placed in the
automatic mode if desired. If any of these errors occur after depressing the error-reset button, then the feed
to the unit is defective and should be investigated. If all is in order, the unit is now ready for operation. All
that is left to do is to select the desired feed and then if desired, place the unit in automatic switch mode by
depressing the “Auto” button. The LED indicator will light indicating automatic control of the switcher.
The unit will remain in this mode until an error is detected, loss of lock occurs, silence is detected or the
alternate feed is manually selected. If any of these events occur, the unit will switch to the alternate path
5
and remain there until the error reset is performed from the front panel or remotely. Please note that the
Auto light will remain lit after an automatic switch but that the unit will perform no further
switching until the error reset is performed. This feature insures that the unit will switch only once after
error or loss of clock is detected and prevents the unit from “hunting” back and forth. In addition, errors
and lock loss indications are held in a buffer until cleared by the error-reset button. This is provided for
troubleshooting purposes. If power is lost to the unit, the AES-302 will reset to “Manual” operation upon
reapplication of power and remain in the channel last selected before power loss.
Theory of Operation – Automatic Switcher Circuit.
The AES-302 is designed to operate in automatic and manual switching modes. Upon application of power
the unit defaults to the manual mode. In this mode switching between channels can only be accomplished
by pressing the desired channel button or commanding the desired remote control pin. With power
application C37 pulls the clock pin 3 of U6A low thus placing the IC in the reset mode whereby pin 1 Q
output is pulled low. This in turn cuts off Q2 preventing automatic switching from occurring. Depressing
the “Auto” front panel button places the unit in automatic operation. The actuation of the “Auto ” button
places a high on pin 6 of U6A which in turn sets Q output high enabling Q2. When an error or silence
sense timeout occurs, a delay of approximately 3 seconds is provided via U16 LM741 which acts as a
comparator. Once the delay of U16 times out the comparator flips pulling the base of Q4 low which
saturates Q3 momentarily. Momentary operation of Q3 is due to C45 being in an initially discharged state.
When Q3 is turned on C45 begins to charge enabling Q3 to pass current. This same current passes through
Q2 whose collector is routed to the proper coil of K1, which is the signal routing relay. K1 fires and
switches to the alternate path. No further switching will occur because the error signal is still present on the
base of Q4. This error signal will remain until the error-reset button is pressed. Once the reset occurs, U16
changes output state back to a positive condition which causes Q4 to be saturated. Once Q4 saturates Q3 is
cutoff and C45 begins to discharge through R32. CR19 prevents unintentional operation of the automatic
switch circuit when errors are reset by momentarily cutting off Q2. C38 aids in preventing unintentional
operation by holding the base of Q2 low until the error has had sufficient time to clear.
The silence sensor accepts audio from the left/right output of the AES-300 module via jumpers J-1 and J-2.
To select both channels place both jumpers in the position closest to the front of the unit. For left channel
only place only J1 in the forward position. For right only place J2 in the forward position. The audio is
then amplified by U15A and is rectified by CR20. The D.C. output of CR20 is then fed to C56 which
stores the D.C. sample until a loss of audio occurs. Once loss of audio is encountered, C56 begins to
discharge through R56 and/or R59. After a time delay of 30 or 60 seconds U15B-7 goes negative and is
clamped by CR22 to 0 volts D.C. This 0 volt indication causes CR21 to conduct pulling the base of Q4 low
which initiates the switching action as described above. If silence sensing is not desired, place S6-6 in the
off position.
Any or all of the errors that appear on the front panel display can be made to actuate a switching operation.
Factory default is all error and silence sensing selected. To change this configuration, remove the top cover
and locate S6 on the motherboard. Refer to table 1 below for switch settings:
