Installation
This section provides instructions for connecting power, the reference input, and the AES
waveform inputs and outputs.
Connecting Power
Plug a 6 VDC power supply (rated at
150 mA
or greater) into the appropriate voltage outlet for
your specific country
, and connect the end of the cord into the jack marked
PWR
. Secure the
locking ring finger tight. The green
PWR
LED lights when power is applied.
Connecting Reference Input
The ADLY-4/A can be synchronized to an external AES3id signal waveform or can be set to
synchronize to the AES channel 1 input based on the position of the
Reference Selection
Switch
.
With the
Reference Selection Switch
in the down position the internal sample rate is locked to
and set by the AES3id signal present on the
External Reference AES3id loop-thru BNC’s.
These BNC inputs accept any valid AES3id 75 ohm signal with a sample rate between 30-50 kHz
and a voltage level between 400 mV and 1 volt peak-peak. Either BNC can be used as
input/output. When a valid AES3id signal is present on the BNC’s and
Reference Selection
Switch
is in the down position, the green
Reference LED
will light on the front of the unit. If the
External Reference BNC’s are not to be used as a loop-thru, the remaining BNC should be
terminated with 75 ohms. Note that when it is necessary to loop the reference to several
SoundPals, the signal must be terminated only once, and always at the last unit in the chain.
With the
Reference Selection Switch
in the up position the internal sample rate is locked to and
set by the AES signal present on the AES Channel 1 input. This input will accept any valid
balanced AES 110 ohm signal with a sample rate between 30-50 kHz and a voltage level
between with 2-8 volts peak-peak. When a valid AES3 signal is present on input channel 1’s 3 pin
Phoenix connector and the
Reference Selection Switch
is in the up position, the green
Reference LED
will light on the front of the unit. See “Connecting the AES waveform inputs” for
information on wiring this input.
Connecting the AES Waveform Inputs
There are four AES input channel pairs (8 channels of audio) available on the rear of the unit via
four male 3 pin Phoenix connectors. Cabling for the balanced inputs is as follows:
Pin 1 is the
+ lead
,
Pin 2 is ground and Pin 3 is the –lead.
A silkscreen of these connections is clearly
visible next to these connectors on the rear of the unit.
Note all four AES input pairs must be
frequency locked at the same sample rate.
Connecting the AES Waveform Outputs
There are four AES output channel pairs (8 channels of audio) available on the rear of the unit via
four male 3 pin Phoenix connectors. Cabling for the balanced outputs is as follows:
Pin 1 is the
+ lead
,
Pin 2 is ground and Pin 3 is the –lead.
A silkscreen of these connections is clearly
visible next to these connectors on the rear of the unit.
All four AES output pairs will be locked to
the selected reference and will be delayed by the same amount set by the three rotary frame
delay switches.
