Manual-2
1 Graphic EQ controls: irty bands are provided for each channel. Each EQ slider has a resolution of 256 steps. e center detent
position guarantees a at response. Slide control travel is 45mm with easy-to-read soft-touch handles.
2 LOW, MID, and HIGH TONE controls: Independent, Accelerated-slope™, 3-band TONE controls allow easy, intuitive
adjustment of tone response without the hassle of adjusting 30 bands. e TONE controls use 12 dB per octave Linkwitz-Riley
lters. e Low/Mid crossover point is 300 Hz. e Mid/High crossover point is 4 kHz. As with the EQ sliders, center detent
provides a guaranteed at response. e range of control is +6 dB to o. Control resolution is 256 steps.
3 LOW CUT and HIGH CUT FILTERS: e LOW Cut Filter is adjustable over four octaves in 64 steps with a frequency range of 15 Hz to
240 Hz. e HIGH Cut Filter is adjustable over two octaves in 64 steps from 5 kHz to 20 kHz.
4 LEVEL controls serve two purposes, when used with the Meters (9):
1) Adjust the INPUT signal level to 0 dBu for good headroom and signal to noise.
2) Compensate for changes in signal level due to lter boost/cut settings by adjusting the OUTPUT signal level to 0 dBu.
e operation of the OUTPUT LEVEL control is reversed. Pushing the control up reduces gain. Pushing the control down
increases the gain. is allows the user to easily adjust sensitivity without aecting the output signal level. Simply grasp both input
and output controls and move together. e ranges of both controls is ±12 dB with a resolution of 256 steps.
5 BYPASS switches have two possible modes of operation. If the rear panel switch is set to BYPASS ALL, all lters and level
controls are bypassed. If the rear panel switch is set to BYPASS FILTERS, only the lters are bypassed. Filters include EQ, TONE
and CUT. Automatic relay bypass hardwires Inputs to Outputs in the event of a power failure.
6 A / B switches determine which set of controls is used by the A-channel or B-channel. Controls aected by the A / B switch are
EQ, TONE, CUT FILTERS, LEVEL, Q switches and ±12 / ±6 dB switches. Bypass switches are not aected.
7 PERFECT-Q™: What you see is what you get. PROPORTional-Q: Classic smooth response. Most users will prefer the
PERFECT-Q position. Some users may prefer the PROPORT-Q setting. See Graphic EQ Controls on page Manual-4.
8 ±12 / ±6 dB switch changes the boost / cut of the Graphic EQ (1) for each channel. Use the ±6 dB unless you really need ±12
dB, the resolution is better.
9 Input and Output Meters are peak responding and indicate the signal level in dBu. Peak-dBu is held and displayed for 1.5
seconds. Attack is instantaneous. Decay is 500 ms for a 20 dB step.
0 When the POWER indicator is on, it indicates that power is turned on. is works with 4 on the Rear Panel (next page).
q CUT-ONLY mode switch: when pressed in, as shown by the LED, sets the range of the EQ sliders 0 to -12 dB (gray number
scale). When the switch is actuated, the output audio is muted and slowly increased to prevent volume surprises.
