WHITE FINGER

FET Optical Compressor

Congratulations on your purchase of the White Finger optical compressor The White !

Finger is a warm sounding pedal useful for both guitar, bass and home recording.

This pedal features optical compression and an FET signal path. Reading these

instructions carefully will ensure that you will get the most out of your White Finger.

- THEORY OF OPERATION -

Optical compressors work by treating an incoming signal with an optically controlled

attenuator (a type of volume control) comprised of a fixed resistor and a shunt opto-

coupled photocell. Because this attenuator is passive, as opposed to the more

common active AGC (Automatic Gain Control) compressor circuits, it doesn’t add an

electronic signature to the signal, thus preserving the tone and character of the

original sound.

The White Finger is a fixed threshold compressor, meaning the threshold remains

constant while you have the ability to change the amount of the signal that goes to

the compressor circuitry. The signal level sent to the compressor is controlled by both

Pre-Gain and Compress knobs. Some gain is needed to adjust the output level so that

it matches the original level and this is accomplished with an FET fixed gain pre-amp

circuit. In general, compressors are used to sustain melody lines, minimize changes in

signal level or add a forward percussive effect to both instruments and drums.

- CONTROLS -

Compress Knob – Varies the amount of compression from minimum (counter-

Clockwise) to maximum (clockwise).

Sensitivity Knob – Changes the characteristic of the compression. As the knob is

turned clockwise, the compression effect becomes more dramatic and percussive.

WARNI Use only the 40VDC/100mA AC adapter the White NG:

Finger comes supplied with. Do not use any other AC adapters. Using

other AC adapters, even those made by Electro-Harmonix, could cause

harm to the unit, the adapter or you. The White Finger does not use

batteries.

Lamp/LED Switch – Selects the light source to drive the optical attenuator. The

LED is very fast and flat in frequency content. Choose this setting for straight-ahead

compression effects and sustain. Choose LAMP for slow attack and a reduced

compression on the treble content. This is great for funk chord playing, voice and

keyboards. Thick and widely adjustable.

SQSH/NORM Switch – Selects between normal attack and a “squashed” long

attack time for the attenuator. This directly affects only the LAMP setting but you will

see a reduction in compression if you leave SQSH on while in LED mode.

Pre-Gain knob – Adjusts the Output level of the signal.

Compression Level LED – Gives a visual indication of the gain reduction caused by

the compressor. The brighter the LED is, the greater the compression.

Status LED – Lights up when the White Finger effect is engaged. If the STATUS led

is off, the unit is in true bypass mode. The footswitch engages/disengages the effect.

INPUT Jack – This ¼” jack is the audio input to the White Finger.

DIRECT OUTPUT JACK – This ¼” jack is connected directly to the input Jack so

that the Input signal is always available.

OUTPUT JACK – This ¼” jack is the audio output from the White Finger. When the

White Finger is in Bypass mode, the output jack is connected directly to the INPUT

jack.
