DRAWMER DS501 – Power Gate

The DS501 is a sophisticated dual channel noise gate with fully tuneable \'Peak Punch\' incorporating a number of features pioneered by Drawmer, which are invaluable to the sound engineer, and not found on conventional noise gates.

• \'Tuneable\' Peak Punch.
• Variable high pass and low pass filters for \"frequency conscious\" gating.
• Comprehensive envelope control, attack, hold, decay, and range.
• Key input for external triggering.
• \"Key Listen\" facility.
• Extremely fast attack time, to preserve the natural attack of the sound.
• Balanced inputs and outputs.
• Stereo linkable.
• Can be used for \"Gating\" or \"Ducking\".
• High audio specification.

Positioned in the Drawmer range over the industry standard DS201 Dual Gate, the DS501 Power Gate features a new dual mode ‘tuneable’ Peak Punch processing section on each channel. In tuneable mode a fully variable frequency selector with a range from 75Hz to 16kHz 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.

Designed principally 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, whilst higher frequency Peak Punch can dynamically emphasise rim shots or the ‘crack’ of a snare drum. Setting up noise gates can be tedious and unrewarding. For example, when attempting to separate a signal from unwanted noise or crosstalk that is relatively high in level, spurious triggering of the gate by unwanted components within the sound can be a serious problem. This can often be experienced in the studio when recording a drum kit. If a gate is used to clean up the snare drum sound it is quite likely that the nearby hi-hats will spill into the snare drum microphone and cause the gate to open. Increasing the threshold level may cure this problem, but then there is a very real danger that any quieter snare drum beats may not cause the gate to open at all and the performance can easily be ruined.

The DRAWMER solution to this problem is the inclusion of two variable filters, one high-pass and one low-pass, which act upon the side-chain keying circuitry. By setting the output switch to key listen the user can hear the action of the filters and adjust them to reject high frequency spillage from the hi-hats. This now enables the gate to only open on the lower frequencies present in the snare drum.

The very fast attack of the DS501 means that it can open in a matter of micro seconds, thus preserving the natural attack of whatever sound is being gated and the comprehensive envelope controls mean 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 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.

Another important role played by the gate is in the reshaping of existing sounds. An example of this might involve a simple sampling delay line used to store a sound to be re-triggered later and added to a mix. A gate can be used to impart a slower attack or faster decay to the sound and careful setting of the decay envelope can effectively hide any noise present at the end of the sample. When using a sampler or drum machine the gate can be considered a triggered envelope shaper, and the wide range allowed by the envelope controls make the DS501 ideal for this application.

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.

Each channel can be individually switched from Gating to Ducking for \'voice over\' applications or the removal of \'clicks\' and \'pops\'.

 Reverbs & Delays

Because it is one of the most desired effects, the FX2000 provides 12 different reverb programs, so you always have the ideal reverb for your live performance or studio needs.

Reverbs include:

    CATHEDRAL
    GOLD PLATE
    SMALL HALL
    ROOM
    STUDIO
    CONCERT
    STUDIO
    STAGE
    SPRING REVERB
    AMBIENCE
    EARLY REFLECTIONS

Specialty reverbs include:

    REVERB – reverb is synthetically turned off after a predetermined amount of time
    REVERSE REVERB – reverb envelope is reversed—it slowly gets louder

Delays include:

    STEREO DELAY – delay is processed across the entire stereo image
    TAPE ECHO – simulates classic tape echo devices, pre-dating the advent of digital delays
    PING PONG – delay signal is "bounced” from left to right at an adjustable tempo

Much More than Just Reverb and Delay

The FX2000 has some of the best-sounding reverb and delay programs, but thatʼs not all. It also provides excellent modulation effects (such as chorus, flanger and phaser), including special variations like musical pitch shifter, tremolo and even a rotary speaker simulation.

Modulation and Pitch Shifter FX:

    STEREO FLANGER (originally generated by playing back two synchronized "reel to reel” tape recorders with a finger rubbing on the flange of one of the take-up reels)
    VINTAGE FLANGER simulates a guitar fl anger stomp box
    JET STREAM FLANGER sounds like a classic analog flanger
    STEREO CHORUS (combines a slightly detuned signal with the original)
    ANALOG CHORUS simulates a guitar chorus stomp box
    VINTAGE CHORUS imitates a classic analog studio chorus
    ULTRA CHORUS creates the sound of an eight person chorus
    STEREO PHASER (combines a second, phaseshifted signal to the original)
    VINTAGE PHASER represents a guitar phaser stomp box
    DUAL PHASER processes the left and right channels separately
    ROTARY (simulation of the rotating speakers typically used on an organ) – Slow or Fast
    PITCH SHIFTER (changes the pitch of the original signal) – can be used to create harmonies with the original signal or replace it entirely with the altered pitch. Choices include stereo, two and three vocal pitch shifter
    VIBRATO – the peak frequency of the tone is periodically and uniformly changed (quickly or slowly)
    TREMOLO (common vintage guitar amplifier effect) – a fast or slow periodic variation in volume
    AUTO PANNING – signal is automatically sent from one side of the stereo image to the other, either once or multiple times

Dynamic FX:

    COMPRESSOR – reduces the dynamic range of the signal, maintains consistent signal level and thus avoids distortion associated with excessive input levels
    EXPANDER – effectively broadens the dynamic range of source signals while reducing background noise
    GATED REVERB – helps reduce background clutter by turning reverb off below a predetermined threshold level. Particularly effective on drum mics and vocals
    ANA. KOMPR/LIM. — similar to COMPRESSOR but with Limiting functionality
    ULTRAMIZER – analyses incoming signal and automatically applies compression across two independent frequency bands
    DENOISER – eliminates or reduces noise and other interference
    DE-ESSER – reduces or removes sibilance (Ssss sound) from signal
    WAVE DESIGNER – allows you to influence the envelope by adjusting Attack and Release of the signal

Psychoacoustic FX:

    EXCITER – adds artificially generated overtones to the original signal, increasing presence and perceived loudness without significant increase in signal level
    ENHANCER – functions much like a dynamic pitch equalizer
    ULTRA BASS – sub-harmonic processor combined with bass exciter and limiter
    STEREO IMAGER – divides the signal into middle and side signals, allowing individual signals to be amplif ed when desired and placed on the stereo image
    ULTRA WIDE – creates a broader stereo image
    BINAURALIZER – also creates a broader stereo image and compensates for crosstalk between both speakers

Filter/EQ FX:

    AUTO FILTER – influences the frequency response of a signal. Two filters are included: low pass allows low frequencies to pass and suppresses high frequency content; high pass does the exact opposite
    LFO FILTER - Controls the rate of oscillation effects
    PARAMETRIC EQ – allows you to control the bandwidth, frequency and amplitude of a signal
    GRAPHIC EQ – the sound spectrum is divided into eight (8) adjacent frequency bands, which can be cut or boosted, bandwidth is predetermined

Distortion FX and Amp Simulations

The FX2000 is also equipped with distortion, amplifier and speaker simulation including VOCAL DISTORTION, TUBE DISTORTION, GUITAR AMP, TRI FUZZ, SPEAKER SIMULATION, RING MODULATOR and LO-FI.

Special FX:

    VINYLIZER – adds clicks and/or noise to the signal, reminiscent of old vinyl records and tape machines
    SAMPLER – allows you to record and playback up to five (5) seconds of program material
    VOCODER – allows the input signal to modulate another signal (usually a synthesizer sound), creating the familiar "talking synthesizer” effect
    VOICE CANCELER – removes mono vocal parts from stereo recordings for "instant Karaoke”
    RESONATOR – simulates and oscillating system that amplifies a specific frequency

Our FX Combinations Go to 11

Sometimes you want to add a little (or a lot) of color to your reverb and delay patches. The FX2000 allows you to layer modulation effects like chorus, flanger, pitch or tremolo with your reverb or delay selections.

Innovation

The ARX AFTERBURNER? is a unique Multi Mode compressor/limiter
designed for use in any professional audio dynamics control application.
Multiple Modes
The Afterburner can be set up and used in three different ways:
In Two channel mode, it performs as two independent compressor/limiters,
with 'industry standard' variable Threshold, Ratio and Output gain. In stereo
mode, our New Adaptive Stereo Link circuitry provides increased stereo
imaging accuracy when linking both channels as a stereo pair. A single front
panel switch puts the Afterburner into its alternative Mono mode, setting it up
as a Single channel, Dual Band compressor/limiter, with separate dynamics
control of both Low and High frequencies, opening up a whole new range of
gain control techniques.
Enhance Switch
In any mode, the Afterburner features an 'Enhance' switch, which provides
frequency restoration to preserve the spectral balance of the audio signal,
compensating for the sagging Low and High frequency response of compressed
program material. Think of it as a 'smart' loudness control.
