DRAWMER S3 O

PERATOR’S

ANUAL

LOW BAND, MID BAND, HIGH BAND

Threshold:

infinity - -32dB

all bands

Determines the level below which compression starts to take

place. The S3 incorporates a Soft Knee, more compression is

applied automatically as the input signal level increases, negating

the need for a Ratio control.

Gain Reduction Meter:

all bands

Eight Leds at 0,-1,-3,-5,-7,-10,-15,-20dB

Big:

Off - On

low band only

Reduces the ducking effect caused by bass energy and effectively

boosts the bass output.

Air:

Off - On

high band only

Use to brighten and enhance the high band detail. Cymbals sound more vibrant without becoming splashy, vocals

sound more open but without becoming sibilant.

Attack:

see Fig. 5

all bands

Controls the speed that the compressor responds to signals that exceed the level set by threshold. Six switchable

Attack settings. All times are nominal, the actual attack time is further modified by the release setting chosen.

Release:

see Fig. 6

all bands

Sets the time taken for the signal to return to normal after the input level has fallen below threshold.

The first three switch positions are fixed and provide progressively increasing release times, while positions F(ast),

M(id) and S(low) cause the release times to vary in a manner which automatically adapts to the dynamics of the

incoming signal.

Gain:

-10 - +20dB

all bands

During compression the signal is attenuated, gain may be required to produce the required output level. In addition,

as the S3 is multi-band, the three gain controls are used to adjust the levels of each band to obtain a desirable

overall signal, or to bring out the bass, treble etc.

Mute:

Off - On

all bands

In the “MUTE” position the signal for that particular band is effectively turned off. Any combination of mute is

available - to hear only the signal of the low band mute the mid and high bands etc.

Bypass:

Off - On

all bands

In the “BYPASS” position the signal for the low, mid, or high band is allowed to pass through to the summing stage

without being altered by the compressor stage (including gain).

Using a combination of mute and bypass switches for the various bands allows the operator to hear and monitor

only the frequencies that are required and so tune the low and high frequency settings.
