Introduction
About the RAC 104
The Extron RAC 104 is a high-performance, four-channel
remote audio controller that adjusts volume and tone for stereo
or mono audio signals. Adjustments are made via the
RAC 104’s front panel controls or through a device connected to
the unit’s RS-232 connector.
The four channels on the RAC 104 can be used as four discrete
mono channels or can be tied into pairs as stereo channels. All
channels input and output balanced or unbalanced signals on
5-pole captive screw connectors.
The unit features smooth volume adjustment and three presets
for each channel. An external 100-240 VAC power supply is
included with the unit.
Features
Volume, bass, and treble controls — Adjust these three settings
using the RAC 104’s front panel controls or an RS-232
device. Set upper and lower limits for volume and tone
using an RS-232 device.
Four discrete channels — Versatile input/output configuration
can accommodate mono audio, stereo audio, or a
combination of the two.
Speed-sensitive volume knob — Turn the knob quickly to
make coarse adjustments or slowly to make fine
adjustments.
Smooth volume adjustment — No audible “stairstepping” or
jumps when volume is adjusted.
Input gain adjustment — Using an RS-232 device, adjust the
input gain to reduce variations in volume between
channels and set an upper volume limit for each channel.
Presets — Save and recall up to three presets for each channel
via an RS-232 device. Each preset saves volume, bass,
treble, and input gain settings.
Balanced/unbalanced inputs and outputs — The RAC 104 is
compatible with both balanced and unbalanced audio,
and can be used as a balanced-to-unbalanced audio
converter.
