General Description:
The 4710 is a digitally controlled, R-C active, 56 band, one-sixth octave graphic equalizer with adjustable high and low-pass filters and 10 memory presets. It is constructed with a full front panel to control every aspect of the equalizer's operation. Factory installed remote control and network options are available. 

High and Low-Pass Filters:
These band limiting filters are adjusted with the built-in software, each in 8 steps, over a range of 10Hz through 160Hz for the high-pass filter and 32kHz through 6kHz for the low-pass filter. The response is 12dB/octave. 

Other Features:
A bypass switch on the rear panel performs a hardwire bypass of the equalizer by connecting the input to the output. A mute relay mutes the output on power-up/down to protect the sound system. The servo-balanced input and output can be operated, unbalanced, without a change in level or dynamic range. Level is adjusted in 0.5dB steps.
