1.OUTLINE

Compact but flexible

This digital audio processor accommodates 2 channels for analog and digital input
and 6 channels for analog output in 1U size. It is available to use for various usage
such as a digital channel divider and an audio signal distributor.

Excellent sound quality

Its frequency characteristic extends to more than 40kHz and dynamic range (A-
weight) is more than 110dB. The excellent sound quality is a result of sophisticated
design from circuit board to components.

Extremely precise data processing

The digital signal processor (DSP) is operates at 96kHz sampling frequency as well
as A/D and D/A. In addition, processed data is transferred at 48bit so that it can
achieve a massive internal digital headroom margin and obtain highly accurate
calculations.

Plenty of signal processing

The SRP-F300 is capable of providing a 31-band graphic equalizers, an 11-band
parametric equalizer, a compressor and a level control for 2-channels of input
signals. For each of the 6-channel outputs, it accommodates low-and high-cut
filtering up to 6th order for crossover, a 3-band parametric equalizer, a peak limiter,
a delay, a phase switcher and a level control. A test signal generater is provided
which has a pink noise and 20Hz -20kHz sine wave oscillator.

Effective adjustment

Signal processing is adjusted by an external computer via REMOTE terminal (RS-
232C) interface. (See “Control Software Manual”). A Windows

 95/98 Graphic User

Interface (GUI) enables quick and simple adjustment.

Storage of up to 50 programs

Once you set up, it is possible to recall the stored programs in the unit without
connecting a computer.
