The 4700s and two channel versions, 4700-2, are digitally controlled, R-C active, 28 band, one-third octave graphic equalizers with adjustable high and low-pass filters and 10 memory presets. They are constructed with or without full front panel controls. Factory installed remote control, network and back lighted LCD display options are available.
Crossover & Pink Noise Options:
The 4700 (but not the 4700-2) can be equipped with either a crossover network card or a pink noise generator card. These options must be installed by White Instruments at the factory. The crossover options include 2 or 3-way, Bessel, Butterworth or Linkwitz-Riley with 6, 12, 18 or 24dB/ octave characteristics.
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 100kHz through 9kHz for the low-pass filter. The response is 12dB/octave.
A bypass switch on the rear panel performs a hardwire bypass of the equalizer by connecting the input(s) to the output(s). A mute relay mutes the output(s) on power-up/ down to protect the sound system. The servo-balanced input(s) and output(s) can be operated, unbalanced, without a change in level or dynamic range. Level(s) are adjusted in 0.5dB steps.
