Installation
The Pro Channel may be employed in a number of setups, including:
• between a microphone and a digital recorder, mixer, or analog recorder;
• in a mixer’s channel insert points;
• between a microphone and signal processors; and
• between electronic musical instruments (synthesizers, guitars, basses, samplers,
acoustic instruments with pickups, etc.) and other gear.
Safety Precautions
WARNING: To avoid the risk of shock or fire, do not expose this unit to moisture. Do
not remove metal panels or chassis parts. Removing any chassis parts exposes
dangerous high voltages. There are no user-serviceable parts inside. Refer all servicing
to qualified personnel.
If your power cord becomes damaged, always replace it with the same type as originally
equipped. Since the cord is detachable, it is possible to replace it with a cord configured
for the wrong voltage. Always refer to the unit’s rear panel to determine the correct
supply voltage, and then choose an appropriate cord.
Powering Up
When the power switch is turned on, the VU meter illuminates. It is important to
remember to turn the Pro Channel on before any monitoring levels or power amps are
turned on. The Pro Channel has the ability to add over 80dB of gain to its input signal
and can cause the unit to produce a “thump” on power up and power down.
Like all tube-based equipment, the Pro Channel needs to warm up before being used.
Allow one to two minutes for the tubes to reach their proper operating temperature. If
the Pro Channel fails to power up when the power switch is turned on, check to see that
its power cord is plugged into an active outlet. If the unit still fails to operate properly,
turn it off and unplug it, and then consult your dealer or A R T’s Customer Service
department.
