QRK Active Speaker User Manual
During the above process, be aware that the level should be set to accommodate the loudest
combined input to the speaker and that distorted or overdriven signals may be damaging to
the speaker and amplifier section. If the sound is distorted (aggressive, fuzzy sounding),
reduce the volume controls so that the loudest output is clean and clearly audible.
QR8K and QR10K models have a TONE control (1), which adjusts the tonal character of the
speaker output. Adjust this clockwise to increase high frequency (treble) content or adjust
anti-clockwise to reduce high frequencies for a more rounded, mellower output.
QR12K and QR15K models have separate TREBLE and BASS controls (4, 5) to adjust the tonal
character of the cabinet. Adjusting clockwise increases bass or treble output and adjusting
anti-clockwise will reduce bass or treble likewise, vertical (12 o’clock) is the neutral setting.
QR12K and QR15K models also have an ECHO control which adjusts the level of echo effect
applied to the microphone input(s) for singers. When using a microphone, care must be taken
to avoid feedback (loud squealing or howling sounds caused by the microphone being able to
“hear” its own sound through the speaker) This can be avoided by keeping the microphone
faced away from the speaker and avoiding high settings of MIC VOLUME, TREBLE, BASS and
ECHO controls.
Before switching the QRK active speaker off, turn down all volume controls to avoid loud clicks
through the speaker. Remove the power lead if the unit is not to be used for long periods of
time
