THE SILENCER
Noise Gate/Effects Loop
Congratulations on your purchase of The Silencer, a sophisticated noise gate with a gated effects loop from Electro-Harmonix. The Silencer can be used as an inline noise gate or it can gate an entire effects loop. Whether you play with a single distortion pedal, or an entire board of effects, noise can be a problem. With control over threshold, noise reduction, and release time, The Silencer can be fine-tuned to fit your system, instrument, and playing style to remove unwanted noise.
– CONTROLS –
THRESHOLD Knob Controls how much level is needed to open the noise gate
and allow your signal to pass through. At full counter-clockwise, the gate
remains open and passes all signals through. As you turn THRESHOLD clockwise
more level is needed to open the gate.
To tune the THRESHOLD knob, we recommend you start with THRESHOLD set to its
minimum position, REDUCTION set to maximum, RELEASE set to minimum, and The
Silencer’s LED lit. Turn up the volume knob on your guitar but hold the
strings to stop any feedback. You should hear noise coming through your
amplifier. Turn up the THRESHOLD knob until the noise disappears, then
continue to turn it up just a little more; this setting makes for a good
starting point.
REDUCTION Knob Controls how much the gated signal will be reduced.
Reduction is variable between -70dB at full clockwise (for maximum noise
reduction) to +4dB at full counter-clockwise (yes you can boost the noise
instead of reducing it if you like). You may find setting REDUCTION between 12
o’clock and 3 o’clock produces a more natural gating effect than it does at
maximum.
RELEASE Knob Controls the speed of the envelope signal that closes the
gate after the input signal drops below the THRESHOLD setting. RELEASE time
varies from a quick 8ms at full counter-clockwise to a slow 4 seconds at full
clockwise. Start with a RELEASE setting of 12 o’clock for a natural sounding
gate effect.
FOOTSWITCH and LED The Footswitch selects whether The Silencer is
engaged or in buffered bypass mode. When the gate is engaged, the LED is lit.
The effects loop remains in your signal path while The Silencer is bypassed.
INPUT Jack Plug your instrument into this ¼” jack which is the main
audio input for The Silencer. The input impedance is 2M. OUTPUT Jack The
OUTPUT jack is The Silencer’s main audio output. The gated signal exits
through the OUTPUT jack. The output impedance is 300.
SEND Jack Connect the SEND jack to the beginning of your effects loop.
The output impedance is 300. The SEND jack outputs a buffered version of the
signal present at the INPUT jack at all times. If you do not need to use the
Silencer’s effects loop, the SEND jack could also be used to split the input
signal. RETURN Jack Connect the end of your effects loop to the RETURN
jack. The signal preset at the RETURN jack is gated by The Silencer. The input
impedance is 1M. If you are not using the effects loop and prefer to use The
Silencer as an inline gate, do not plug anything into the RETURN jack.
9V Power Jack Although The Silencer accepts 9V Batteries, it can also be
powered from an Electro-Harmonix 9.6DC-200BI power supply. Plug the output of
the AC adapter into the 9V power jack located at the top of the Silencer. The
Silencer draws 22mA at 9VDC with a center-negative plug. The Silencer accepts
Boss® and Ibanez® style AC Adapters.
– REMOVING BOTTOM COVER/CHANGING THE BATTERY
To change your 9-volt battery, you must remove the 4 screws on the bottom of
The Silencer. Once the screws are removed, you can take off the bottom plate
and change the battery. We recommend 9V alkaline batteries. Please do not
touch the circuit board while the bottom plate is off or you risk damaging a
component.
