Inputs and Outputs
Eleven Band Equalization: This
equalizer gives you eleven bands with which to optimize the sound of your
system. The center frequencies of each band are 31.5Hz, 63Hz, 125Hz, 190Hz,
250Hz, 500Hz, 1KHz, 2.2KHz, 4.5KHz, 9KHz and 18KHz. Each control has a boost/cut
range of 12dB.
BBE Processing: This circuit
improves the overall clarity, definition and fullness of music by correcting
phase errors in reproduced sound and restoring it to its original levels.
High and Low-Pass Filters: When the low-pass filtered subwoofer output is switched on, the front and rear outputs become high-pass filtered outputs. The crossover frequency is variable from 50 to 120Hz; the high and low-pass crossover points are not independent of each other. The low-pass filter has an 18dB/octave slope, and the high-pass filter has a 12dB/octave slope. The high and low-pass filters allow you to fine tune the frequency output range your subwoofer and main speakers to achieve a well balanced sound.
Sub-Level Control: The
subwoofer output level control has a range of 0 to +15dB. This lets you
control the overall volume of your subwoofers and match them to your system.
Control: A front panel fader control is provided to permit fading between
the front and rear pre-amp output jacks. The subwoofer output jacks are of the
non-fading variety, so they are not controlled by the fader.
Phase Control: A switch on the back panel of the equalizer allows you
to set the subwoofers output at either 0 degrees (in phase) or 180 degrees (out
of phase). This control allows you to compensate for acoustic problems that can
occur because of speaker placement and the acoustic environment of
your vehicle's interior.
Switch: A switch on the back panel of the equalizer lets you set the
subwoofer output to either a mono or a stereo output signal. If you are using
only one subwoofer, set the switch to mono. If you are using two or more
subwoofers, the switch may be set to either mono or stereo. In the stereo mode,
you may gain some sound separation (depending upon the music material). In the
mono position, the subwoofers will share the load more equally and can play
- Slide Controls:
each equalizer slider has a green led
- Equalizer Defeat Switch: in
the "off" position the switch glows green; in the "on"
position it glows amber and all of the sliders are dark
- BBE Switch: in the
"off" position the button glows green; in the "on"
position the button glows amber
- Subwoofer Level Controls: the
slide control glows amber when the sub function is "on" and is
dark when "off"
- Input Level Indicator: 5 red
LED's glow at various rates to indicate input voltage level
Pre-amp Inputs: A pair of gold
plated RCA jacks (left and right) are provided to input the signal from a head
Pre-amp Outputs: A pair of
front (left and right) and rear (left and right) gold plated RCA jacks are
provided for the full range and filtered high pass connections to the
Subwoofer Outputs: A pair (left
and right) of gold plated RCA jacks are provided for connection to the
amplifier(s) that run the subwoofer(s). These outputs are switchable between
stereo/mono and are non-fading.
