DRAWMER 1970 – Dual FET Compressor and Preamplifier

The 1970 Dual F.E.T. Compressor and Pre-Amplifier builds on a heritage inspired by the first pro audio "tool box" compressor, the illustrious Drawmer 1960, but with a greatly expanded feature set, making it one of the most adaptable mic preamplifier/compressors on the market today. Bringing vintage audio characteristics at an affordable price.

Whilst the feature set of the 1970 is similar to the Drawmer 1960, and the layout of the controls will add to the comparisons, the 1970 has been greatly improved and the D.I. EQ has been fine tuned to be more accurate than its stable-mate, with various enhancements.

The 1970 use the latest THAT Corporation technology in the 2 mic preamps to provide ultra clean, transparent and precise recordings that can be processed at a later stage using your favourite warming method, be it saturation, valve, transformer or tape. In addition each channel is capable of 66dB of gain, with switchable mic impedance for accurate mic matching to bring out the best from any microphone used. Phantom power, phase reverse and a high pass filter are also included.

From tracking instruments via the dedicated D.I. input, to recording vocals via the ultra clean mic pre's, recording a guitar cabinet with two microphones, or a singer playing guitar, or even stereo buss compression using the comprehensive linking and mix facilities, the 1970 is the perfect versatile tool for any studio or live event.

• Two THAT Corporation ultra clean mic pre's with 66dB of gain with phantom power and switchable mic impedance for accurate mic matching.

• Separate Line & Mic input XLR's

• A pro quality instrument DI input with low and high EQ.

• Can be used as 2 mono tracking compressors or 1 stereo buss compressor (avoiding image shifting) via the class leading comprehensive linking facilities.

• FETs can be bypassed altogether to provide ultra clean outputs.

• Standard controls such as Threshold, Ratio, Attack & Release, with 8 LED GR Metering on each band.

• Rear panel Side-chain insert points provide even further control.

• ‘Big’ and 'Air' Modes Help to preserve the very deep lows and Enhance the sparkling highs.

• Variable Wet/Dry Mix plus Output Gain knobs on both channels give a 'Parallel Compression' function without the need for external mixing devices, providing complete and effortless control over the amount of compression used and output levels.

• Two backlit Analogue V.U. Meters with Switchable +10dB Rescale Mode. Time delay relays on outputs for clean power up/down.

• Internal Low Hum Toroidal Linear Power Supply with Voltage Selector Switch.

• Classic Drawmer build quality with rugged steel chassis and aluminium front panel.

• Designed and Handmade by Drawmer in the United Kingdom.

Features
Unique High Density design puts SIX gates in
minimum rack space
Intuitive, 'user friendly' layout
Balanced Inputs and Outputs
Fast, low noise opto-coupler circuitry
Sidechain/Key Input points on each channel
Hardwire Bypass switch on each gate
Flawless performance in any audio environment

The sheer amount of effects and signal processors required for today's
standards of audio production puts a great strain on the available space
in equipment racks, both in the studio and on the road.
So, in order to give engineers more control in less space, we've created
the ARX Sixgate; Six full function noise gates neatly housed in a compact,
all steel 1 RU package, without sacrificing features or quality.
Why Six gates?
Research shows that the majority of noise gates get used on drum kits,
which means using typically 5 to 6 gate channels. Compare this to the
two or maybe 4 channels that most other units have, and you'll see the
reason for the Sixgate's success.And, by using a minimalist approach to
drum gates, the ARX Sixgate has enough gates left over for backing vocals
and other instruments.
Industry Standard controls
Front panel controls for each gate consist of the 'Industry Standard' controls
for Release, Depth and Threshold, plus Red and Green LED displays to indicate
Gate Open or Closed status, and an IN/OUT hardwire bypass switch.
In addition to this, each gate has a blank panel to write on for easy confirmation
of gate assigns. No more pieces of masking tape stuck everywhere!
Ultra Low Noise
Internally, each gate has proprietary ARX ultra low noise high-speed opto-coupler
circuitry with program dependent Attack time, which tracks the incoming signal to
automatically determine optimum gate response.
Balanced Inputs and Outputs
The rear panel features true differential Balanced Inputs and Outputs for each gate,
on insulated TRS jack connectors.Each gate channel also has Individual Key Inputs/
Sidechain access insert points which can be used either for gate control by an external
signal, or for frequency sensitive gating (when used in conjuction with an external
equalizer such as the ARX EQ260).
Universal AC Power
AC power range on the Sixgate is a universal 100 to 120V or 220 to 240V, and is
connected to the unit via a standard 3 pin IEC connector, with built-in fuse and voltage
switch.
The Sixgate's unique combination of High Density design, intuitive 'user friendly' controls,
and clean uncluttered layout make it a truly useful audio tool for all applications.
