Features

• The slow, “gain-riding” Gated AGC function erases long-term input level variations and corrects loudness differences between diverse program sources.

• A 3-band Compressor/Equalizer optimizes “spectral density” to yield a more uniform program timbre, improved intelligibility and long-term listenability.

• A sophisticated Peak Controller tames instantaneous “audio surges” which, unchecked, can cause severe program distortion.

• The built-in RS-232 control bus allows computer selection of all processing parameters if desired.

Specifications

Frequency Response

±1dB, 50Hz–4.9kHz. High-frequency cutoff is fixed by an overshoot-compensated multipole low-pass filter appropriate to Internet audio frequency limitations.

Distortion

Typically under 1% THD at any PROGRAM DENSITY setting, and at PEAK PROCESSING settings which maintain negligible clipping depth.

Noise

Better than 60dB below the fully-limited output level.

Variable Equalization

• HF: –6dB, –3dB, 0dB (flat), +3dB, +6dB.
• LF: –6dB, –3dB, 0dB (flat), +3dB, +6dB.

PROCESSING VARIABLES

• PROGRAM DENSITY controls “blending” within the tri-band dynamic range compression section, as well as the compression release characteristic. Eight incremental settings range from a slow, blended (single-band) function to fast, fully-independent 3-band operation.
• PEAK PROCESSING programs the action and interrelation of the program peak limiter and clipper circuits in eight MIN to MAX increments.

Input

Active-balanced, bridging; accepts nominal program line levels between –15dBu and +15dBu.

Output

Active-balanced, 200-ohm resistive source; delivers 0dBm to +15dBm into 600-ohms.

Remote Control Provision

An RS-232 serial data port (DB9 connector) allows all processing presets to be programmed by an IBM-compatible computer, directly or via modem. Supplied software runs under Microsoft Windows® 95/98.

Power Requirement

105–130VAC or 210–255VAC, 50/60Hz; 15W

Size and Weight

13/4”H x 19”W x 10”D (1U); 10 lbs
