Quad Noise Gate has been designed to the highest specification to complement
the DS201 Dual Noise Gate, acknowledged as the 'industry standard' gate
throughout the world.
that there are many general gating applications which require equipment that is
simple to operate and which occupies the minimum of rack space, Drawmer have
designed the DS404 Quad Noise Gate utilizing new and unique 'Programme
Adaptive' circuitry. This makes the DS404 ideally suited for use over a wide
range of input signals, ranging from drums and other percussive instruments
through to vocals, pianos and even complete mixes.
available on the DS404 include:
Sensitive. The provision of variable Low-Pass and High-Pass Filters allows
'without compromise' frequency selective gating. The unit can be switched for
either Internal or External Key source and the KEY LISTEN facility enables
monitoring of the filter setting.
Gating. Each channel of the DS404 can be operated as a HARD or SOFT gate,
providing quite different characteristics. Two coloured LEDs clearly indicate
mode status. In the HARD mode the DS404 offers ultra-fast response time, stable
triggering with complete freedom from chatter around threshold and a
specialized release contour which is ideally suited to drums and other
percussive material. In the SOFT mode the DS404 becomes a versatile Expander
capable of handling vocals and sub mixes. Drawmer's unique 'Programme Adaptive'
circuitry is used to optimise the attack time and ratio as well has having some
effect on the manual release setting . A more gentle release characteristic is
utilized to complement the SOFT gate
A fully variable threshold control provides a range from +20dB to -70dB.
Control. A fully variable release control is provided with release times from
10 ms to 5 sec to ensure that essential envelope control is not sacrificed in
exchange for an economy in rack space.
Attenuation Range. The DS404 has switchable
attenuation between 90dB and 20dB to allow for applications where a complete
mute is not desired. Chain Linking. Operating the LINK control switches the
channel on the right to SLAVE operation, where its gating mode, threshold and
envelope characteristics are controlled by the MASTER (left) channel. Any
adjacent three channels or two stereo pairs can be linked in this way for use
in any conceivable situation where linking may be required.
Displays. Drawmer's familiar tri-colour LED display is once again utilized as
the optimum method for indicating the envelope status for each channel.
DS404 is provided with balanced inputs and outputs on XLR connections.
