Chapter 2:
Setting Up the ATR-1a
Setting up the ATR-1a is a very straightforward.
1.Find a suitable location. The ATR-1a 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-1a.
3.First, connect the power supply’s 7-pin DIN connector to the AC INPUT jack on the rear of the ATR-1a. 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-1a via MIDI, connect a MIDI cable from your MIDI source to the ATR-1a’s MIDI IN jack.
An Important Note: Unless you plan to be defining the ATR-1a’s target pitches via MIDI, be sure that MIDI NOTE MODE is set to OFF in the System Edit pages (see page 29 for details). If MIDI NOTE MODE is set to ON and no MIDI note data is present, the ATR-1a will pass through all audio unprocessed, regardless of the settings of the Program Scale Page — giving the impression that the ATR-1a is not functioning.
An Important Note About Grounding: The ATR-1a 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. For the absolute best sonic performance, ensure that your input and output are fully balanced.
