Stampa la paginaThe Drawmer DS201 is a sophisticated dual channel noise gate, which may be used as two
independent channels or linked for true stereo operation. It incorporates a number of
impressive features, many pioneered by Drawmer, which are invaluable to the sound
engineer and not found on conventional noise gates:
Variable high-pass and low-pass filters for 'frequency conscious' gating;
Comprehensive envelope control, attack, hold, decay and range;
Extremely low-noise and low-distortion circuitry;
Ultra-fast response time;
Comprehensive side-chain filtering;
'Key listen' facility;
'Traffic light' display giving clear indication of gate status;
Balanced inputs and outputs.
These features and the DS201's user-friendliness have helped it to become the worldwide
'industry standard' noise gate.
All input and output connectors are balanced XLRs, with the wiring convention being: pin 2
hot, pin 3 cold and pin 1 ground. For unbalanced operation, it is important to short pin 3 of
the XLR connector to ground (pin 1) at both input and output.
Key inputs are made via ¼" mono jack connectors. If the Key jack sockets are permanently
wired to a patch bay, it is important that the patch bay sockets are fully normalised to
prevent random unwanted triggering.
If earth loop problems are encountered, never disconnect the mains earth but instead, try
disconnecting the output signal screen at one end of the cables connecting the DS201 to
the patchbay, we suggest inside the XLR connector itself. If such measures are necessary,
balanced operation is recommended.
