Functional Description
The RPQ-2150 is a 2x15-Band stereo graphic equalizer with additional built-In active subwoofer
crossover with adjustable frequency. It sports a switchable 6/12dB range, a PeakID system for feed-
back alert, switchable 25Hz Low-Cut filters and indivdual output level meters for each channel.

AC inlet and fuse holder. Use the supplied AC cord to connect the unit to AC mains. Make sure
voltage and frequency stated and set on the unit comply with your local AC supply. The fuse
can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC cord
first, pull out the fuse drawer and replace the fuse ONLY with a fuse of SAME voltage and
rating. If the fuse blows again after replacement, hand over the unit to qualified service person-
nel.
OUTPUT connectors (channel A and B). These are both balanced XLR and TRS connectors in
parallel. Connect following devices of your sound system (amplfiers, etc) here.
INPUT connectors (channel A and B). These are both balanced XLR and TRS connectors in
parallel. Connect preceding devices of your sound system (mixers, etc) here.
SUBWOOFER OUTPUT connector. This is a balanced XLR output for the mono subwoofer
signal. The crossover frequency is determined by the rear-panel frequency control (5).
SUBWOOFER XOVER FREQUENCY control (for both channel A and B). This control sets the
crossover frequency between the mono subwoofer and the stereo mid/high frequency
outputs of channel A and B (2). The frequency can be adjusted from 30 to 200Hz.
INPUT control. This adjusts the input signal level in a range of +15 to -15 dB. A LED indicates
the status.
LEVEL meter. Displays the output level at connectors (2) in 3 steps from -20 to +6dB. An over-
load LED indicates when the +18dB limit is reached.
ACTIVE switch. This enables or disables the entire equalizer section. As long as the switch is
not depressed or while the equalizer is not powered up, the EQ circuit is bypassed. This can
also help to compare the original unprocessed signal with the processed signal. A LED
indicates the status.
LoCUT switch. This switch activates the 25 Hz high-pass filter with a 12 dB/Octave slope for
protection against infrasonic signals. A LED indicates the status.
PeakID switch. Pressing this switch activates the PeakID system, which shows by means of
LEDs in the relative frequency band’s fader shaft where the acoustic energy is located in the
audio spectrum. An illuminated fader LED hence indicates a peak in energy, and can help to
identify a feedback and reduce the same by lowering this fader. A LED indicates the status.
RANGE switch. This alternates between the maximum value of boosting/attenuating of
individual frequencies from 12 dB to 6 dB (switch depressed).
FREQUENCY CONTROLS. These are 15 sliding controls per channel for individual frequency
bands. In the middle position, the particular frequency range is not processed; moving
upwards creates a boost, moving downwards attenuation. While boosting frequencies,
observe the ouput level (7) to avoid clipping.
PeakID LEDs. These indicate the signal level of their particular frequency ranges through their
varying illumination intensity, helping to identify energy peaks and thus possible feedback.
POWER switch. Switches the unit on and off. Make sure to switch the unit off when not in use.
