Digitool
aES INPut:
The Digitool has a stereo AES/EBU receiver that accepts AES3 encoded, stereo digital audio. It has an
integrated wide-range sample rate converter that will accept common audio sample rates up to 192
kHz. The converter has a 140 dB dynamic range. The AES input can be selected on the input HARDWARE
screen in odd/even channel pairs.
auDIo outPutS:
The audio outputs are servo balanced. This ensures that the output level is the same when driving a
balanced or properly connected unbalanced input. The maximum output level produced by a full scale
digital signal, measured in dBu, can be set in the OUTPUTx menu, HARDWARE screen. This adjusts the
gain of the output circuitry after digital to analog conversion so that dynamic range can be maximized.
If it is necessary to drive an unbalanced input, the (+) output terminal is typically connected to the
receiving product's signal input and the shield to ground. The (-) output terminal should be connected to
ground at the Digitool output terminals.
CoNtroL rS-485 Port:
For convenience, there are two RJ-45 connectors connected to the Digitool RS-485 control port. This port
is used to connect serial controller products such as the Peavey Architectural Acoustics D1V and D4S. The
function of these controllers is programmed within the Digitool and can be used to adjust signal levels,
mute signals and recall system presets. The Digitool provides limited power on this connector to supply
connected remote modules. See the specifications section for details.
The D4S has two different control modes. "Switch mode" commands are used to perform mute functions.
"Trigger mode" commands are used to recall presets. The D4S and D1V each can serve 4 consecutive
device ID numbers (With the dip switches on those control modules set to 1 for example, serial control
IDs 1-4 can be controlled by that module. See the manual of the wall control module for details).
CV:
There are eight control-voltage (CV) ports on the rear of the Digitool. These inputs have an internal
voltage supply that simplifies connection of an external control. A switch or potentiometer (variable
resistor) can be directly connected between the (+) and the GND terminals of a CV input. If a
potentiometer is used, a value of 10 k Ohms or less is recommended. Closing the switch, setting the
potentiometer for minimum resistance or inputting 0V, sets the selected CV control to maximum level or
un-mute.
The CV input can also be controlled by an external voltage. Driving the + input from a low impedance
voltage source, overrides the internal supply allowing the external voltage to take control. The external
voltage source should be from 0 to +10 Volts referenced to the ground terminal.
SECurIty:
There are several levels of security that can be activated on your Digitool. These include the ability to
lock local editing, remote editing and the front panel mute buttons. The security setup screen is located
under the UTILITIES menu. The default password is 1234. When you lock the Digitool, be sure to change
the password and store that password in a safe place. If you encounter problems, contact Peavey
