Chapter 2:
Setting Up the ATR-1
Setting up the ATR-1 is a very straightforward.
1. Find a suitable location. The ATR-1 is designed to be mounted in a
standard 19-inch equipment rack.
2. Confirm that the included power supply is correct for the electricity in
your part of the world. If you are not sure, or the power supply has a
plug that is incompatible with your wall sockets, contact your local
Antares dealer for help.
Important! Do not attempt to modify the supply or use any other supply that is not
specifically intended for the ATR-1.
3. First, connect the power supply’s 7-pin DIN connector to the AC INPUT
jack on the rear of the ATR-1. Then plug the power supply into an AC
outlet.
4. Connect a balanced or unbalanced audio input to one of the INPUT
jacks (see Chapter 4 for details).
5. Connect a cable to one of the OUTPUT jacks and route the output as
appropriate for your application.
6. If you will be controlling your ATR-1 via MIDI, connect a MIDI cable from
your MIDI source to the ATR-1’s MIDI IN jack.
An Important Note About Grounding: The ATR-1 is an extremely quiet piece
of gear. When properly connected and grounded, noise and hum will be
inaudible. However, as you’re no doubt well aware, every studio has its own
unique quirks when it comes to connections, grounding and noise.
To help ensure optimum performance, the ATR-1 is equipped with a rear-
panel selector switch that lets you choose either circuit board ground or
chassis ground. Which setting is best for you will depend on your particular
studio setup. If you experience any noise or hum when first connecting the
ATR-1 in your system, try setting the selector switch to the other position
(whichever that may be).
