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.
