is 0 degree phase shift, at the All Pass filter center frequency there is -180 degrees of phase shift, and at high frequencies there is -360 degrees of phase shift.

Each input channel has an EQ On/Off button for all filters, and in turn each filter band has its own bypass button. The Flatten Curve function returns all filters to 0dB, but preserves the frequency and bandwidth of any used filters.

8.1g Noise Gate

Noise gates are used to minimize unwanted or ambient low level signal from an individual mic input. THRESHOLD is the level above which an input signal will pass through, and below which its signal is turned off. RANGE is the amount of attenuation in dB which the noise gate attenuates the signal when the gate is off. ATTACK and RELEASE control the time characteristics of the gating action. Attack sets the amount of time it takes for the gate to open or gated signal to turn on. Release sets the time required for the gate to close back up when the input signal falls below thresh- old.

8.1h Autoleveler

An Autoleveler is a dynamics processor used to automatically boost or cut a signal to a user defined target level. TARGET LEVEL is the primary setting in an autoleveler, as it determines the desired constant level to which an input is boost or cut. Both basic mode and advanced mode utilize the target level control, but basic mode simplifies setup. In BASIC MODE, target level, action, and maximum gain are the available controls. ACTION is selectable to gentle, normal, or aggressive, and automatically adjusts the following controls found in advanced mode:

Action	Ratio	Hold Time	Gain Incr. Rate	Gain Dec. Rate
Aggressive	10:1	0 Sec	20ms/dB	5 ms/dB
Normal	4:1	1 Sec	50ms/dB	10 ms/dB
Gentle	2:1	2 Sec	100ms/dB	20 ms/dB

Thr =	Max Gain
	(1/ratio - 1)

MAXIMUM GAIN controls the threshold below target using the follow- ing formula:

In ADVANCED MODE, THRESHOLD BELOW TARGET determines the input signal level relative to the target level, above which the autoleveler increases gain, and below which no action is taken. RATIO is defined as the relationship of input level change in dB to output level change in dB. It is a measure of how aggressively the autoleveler changes the gain to maintain a constant output target level. GAIN INCREASE RATE and GAIN DECREASE RATE are used to prevent sudden, choppy sounding level changes to an input signal having a wide dynamic range. HOLD TIME is used in conjunction with gain change rate, and is defined as the time after the input signal falls below the threshold during which the autolever’s gain is held constant before it re- turns to unity gain. The purpose is to reduce the amount of gain “chatter” and abrupt signal cutoff when the input signal is hovering around the threshold level. Advanced settings which are different than the three Basic action set- tings results in a USER DEFINED display in the basic action control.
