6.4.3. Adjustments Available Only with Remote Control

In addition to FBX, graphic, and high and low cut filters, your Graphi-Q2 can provide fully programmable

parametric filters. These filters are accessible only through GRQ-Remote software. Each channel of

your Graphi-Q2 can have up to 12 total filters, which can be configured as any combination of

parametric, fixed FBX, or dynamic FBX filters. See Section Eight for a complete look at GRQ Remote

Control Software.

6.5. COMPRESSOR/LIMITER CONTROLS

6.5.1. Front Panel Control

COMPRESSOR controls are located immediately to the right of the FBX

controls. Front panel controls consist of standard RATIO, THRESHOLD,

and GAIN makeup knobs, and two horizontal LED ladders showing channel

input gain on the top, and compressor gain reduction on the bottom row.

RATIO ranges from 1:1 to infinity: 1 (limiting).

The input level THRESHOLD, at which compression is engaged, can be

adjusted from -30 dBV to + 31.5 dBV.

The output gain of the compressor can be increased or decreased by

12 dB (this will also serve as the control for the overall output level of

the box).

Compressor KNEE, ATTACK, and RELEASE settings can only be set using

the Remote Control Software, and will default to the last settings programmed. (In addition, the remote

software will allow setting of a separate limiter threshold.) The factory default settings are attack = 15

mSec, release = 400 mSec, and knee = 20. These will remain in place until they are reprogrammed using

the software (see Section 9.5.2 for detailed information on Compressor/Limiters and Section 8.2.6 for

using the Graphi-Q2 Remote Control Software Compressor/Limiter control).

6.6. DIGITAL DELAY CONTROLS

6.6.1. Front Panel Control

DIGITAL DELAY controls are located to the right of the COMPRESSOR controls.

You may delay the output of the Graphi-Q2 audio signal by up to 999.96 mSec

(essentially one second) by using the up/down increment buttons just below the

display showing the amount of delay in mSec. Delay adjustments may be made

with 20-microsecond precision.

For the GRQ3121 model, the digital delay adjustments from the front panel will

affect ONLY the Output B signal. Output A will remain undelayed. You may of

course alter the delay setting for either output using the GRQ Remote Software

(see Section Eight). Note: For a complete discussion on using delays in sound

systems (and we mean complete), see Section 9.4.

When the Graphi-Q2 is first turned on, the firmware version will display briefly within the Digital Delay LED

screen. See Section 6.2.3 for how Tweek-n-Peek uses the Digital Delay LED.

6.7. BYPASS

6.7.1. Front Panel Control

BYPASS controls are located at the far right of the Graphi-Q2 front panel. Separate push

button controls allow independent bypass switching for graphic EQ, FBX, and digital

delay settings. For two-channel Graphi-Q2s, separate bypass controls are available for

each channel as well. When any feature is bypassed, the LED within the switch will

illuminate.

Turning off power to the Graphi-Q2 will place the entire unit in hardwire bypass. Please

note that a sudden bypass of FBX filters may result in a sudden burst of no-longer-filtered

feedback. It ain’t pretty when this happens, so proceed cautiously.
