DESCRIPTION
- 3-way stereo active crossover frequency divider with subwoofer.
- Audio signal control with individual adjustment of the gains level of the filter in each way (bass, mid, treble
and subwoofer), as well as the frequency cutoff of the subwoofer filter and the mid-bass and mid treble
filters.
- Independent subwoofer output.
CONTROLS AND FUNCTIONS
FRONT PANEL
1.-
POWER
: on/off switch.
Note
: always switch the unit on before the amplifier and switch it off afterwards, to avoid damaging the
loudspeakers.
2.-
CHANNEL 1
: channel 1 controls.
3.-
SUBWOOFER:
subwoofer output channel controls.
4.-
CHANNEL 2
: channel 2 controls.
5.-
LOW-MID XOVER FREQ
: simultaneously adjusts the cutoff frequency for the bass low pass filter and
the lower cutoff frequency for the mid band-pass filter. The cutoff frequencies can be selected from
between 70 Hz and 1 kHz. The filter slope is 24 dB/octave.
6.-
MID-HIGH XOVER FREQ
: simultaneously adjusts the higher cutoff frequency for the mid band-pass
filter and the frequency cutoff for the treble high-pass filter. The cutoff frequencies can be selected from
between 480 Hz and 7 kHz. The filter slope is 24 dB/octave.
7.-
LOW CUT 30 Hz
: bass cut off with high pass filter with 30 Hz cut off frequency with a slope of 12
dB/octave, it is used to minimize problems caused by subsonic signals, to avoid noise and buzzing and
to prevent bass echoes in the loudspeakers.
8.-
LOW GAIN:
bass filter gain control (bass output level).
9.-
PHASE
: this switch inverts the mid audio signal phase 180°. Normally it is not necessary. However, in
cases it can be. For example, if you use an XLR connector with inverted polarity and also to compensate
phase cancellation.
Note
: before touching these controls, always lower amplifier outputs to avoid damaging the
loudspeakers.
10.-
MID GAIN
: mid filter gain control (mid output level).
11.-
PHASE
: this switch inverts the treble audio signal phase 180°. Normally it is not necessary. However,
in cases it can be. For example, if you use an XLR connector with inverted polarity and also to
compensate phase cancellation.
Note
: before touching these controls, always lower amplifier outputs to avoid damaging the
loudspeakers.
12.-
HIGH GAIN
: treble filter gain control (treble output level).
13.-
SUB GAIN
: sub-bass filter gain control (sub-bass output level).
