Drawmer DS501 Power Gate Dual-Channel Noise Gate with Peak Punch
Key Features
  • Sophisticated Dual-Channel Noise Gate
  • Tuneable Peak Punch
  • Frequency-Selective Gating: HPF & LPF
  • Internal, External Key plus Key Listen
Positioned above the DS201 in Drawmer's range of industry-standard noise gates, the DS501 is a sophisticated, dual-channel noise gate with full AHDR envelope controls and, for the first time, a highly programmable Peak Punch function that lets you add transient punch to the leading edge of the envelope, fattening drums and dynamically adding emphasis to select frequencies. The DS501 doesn't stop there; you get plenty more controls with selective gating or ducking for VO applications or the removal of clicks and pops, stereo channel linking for gating two channels from one source, and much more.

Drawmer DS501 Overview

Positioned above the DS201 in Drawmer's range of industry-standard noise gates, the DS501 is a sophisticated, dual-channel noise gate with full AHDR envelope controls and, for the first time, a highly programmable Peak Punch function that lets you add transient punch to the leading edge of the envelope, fattening drums and dynamically adding emphasis to select frequencies. The DS501 doesn't stop there; you get plenty more controls with selective gating or ducking for VO applications or the removal of clicks and pops, stereo channel linking for gating two channels from one source, and much more.

With variable high- and low-pass filters, you can adjust your gating to act on high- or low-frequency material, passing through only what you want, and rejecting unwanted frequencies, such as bass drum rumble or spillage from hi-hats. Comprehensive key input facilities allow you to choose between external and internal key sources as well as a Key Listen function that lets you process output signals with the key filter. The DS501 has an internally switched power supply for global compatibility, and includes an AC power cord to get you started.

Note:
Internal voltage switching requires disassembly of the chassis and should only be performed by a qualified technical engineer.
Peak Punch
Designed primarily for drum and percussive gating applications, tuneable Peak Punch makes it possible to add transient punch to frequencies lacking in individual drum sounds, adding greater definition and presence to the gated signal. Using low-frequency Peak Punch adds depth to thin drums, while higher frequency Peak Punch can dynamically emphasize rim shots or the crack of a snare drum.

In tuneable mode, a fully variable frequency selector with a range from 75 Hz to 16 kHz allows the user to shape the transients of the gated signal and tune in to the particular area of the audio spectrum where the Peak Punch is to be active. In addition, a variable More control allows the user to tailor the amount of processing. A secondary Full-Band Peak Punch mode is also available.

Ultrafast Attack Times
The very-fast attack of the DS501 means that it can open in a matter of microseconds, thus preserving the natural attack of whatever sound is being gated, and the comprehensive envelope controls means that the gain can be changed at whatever rate best suits the material being processed. With vocals for example, a fairly fast attack is needed, so as not to clip the leading consonants, but a slower release time will prevent the end of words from being clipped off and will also fade out any noise gradually rather than cutting it off abruptly. This latter point is very important as the human ear is far more sensitive to rapidly changing noise levels than to a constant low level noise.
Key Functions
The unit can be switched to accept a key input, which allows the gate to be triggered externally. An example of this would be to use a snare drum signal to open the gate on a separate ambient microphone to create a natural alternative to gated reverb. The D501 essentially features five key-based gating settings across two switches, including:

  • Int: this switch causes the gate to respond to the dynamics of the signal being processed
  • Ext: in this position, an external audio signal fed to the key input is used to control the gate, allowing one sound to gate another
  • Key Listen: this allows the effect of the key filters on the program material to be heard at the output
  • Gate: this switch position is selected for normal gate use; the filters only affect the way the unit responds to the incoming program material, with no effect on the output
  • Bypass: this position routes the input signal to the output with no processing
Note:
To use the DS501 as a filter instead of a gate, leave it in the Key Listen position.
