TL AUDIO C-1 DUAL VALVE COMPRESSOR

The new C-1 compressor maintains its position as the most flexible, polished
sounding high end compressor on the market today. Now featuring a spectacular
raven blue 6mm CNC milled aluminium front panel, General Electric US military
specification valves, high retention gold plated ceramic valve bases and circular
back-lit VU meters, the new C-1 is even fatter sounding and more rugged than
its legendary predecessor.
All controls are continuously variable (unlike some other units with switched
parameters) and high quality onboard mic preamps allow direct-to-tape recording
of microphone sources. Stereo front panel instrument inputs mean a keyboard or
guitar can feed straight into the C-1 and down to tape with a minimum of fuss.
Whether the C-1 is tracking vocals and instruments or adding roundness and warmth
to a complete mix, it will become an indispensable part of your signal path within hours.
The C-1 features a low noise solid state preamp followed by two valve stages per channel.
The valves are General Electric ECC83/12AX7A types, run from a stabilised 250v DC power
supply. The first valve stage acts as a voltage amplifier, with the second stage forming part
of the gain control element. The gain control is performed by our own unique transconductance
stage which avoids the use of VCAs - thus improving transparency and minimising distortion,
which is virtually constant at 0.05% over the full bandwidth. The frequency response of
the C-1 is virtually flat between 20Hz and 40kHz, and measured between -3dB points,
the C-1's bandwidth is a staggering 5Hz to 70kHz!

The latest addition to the 10 Series product line, the dbx® 1074 QuadGate™, is the perfect companion to the 1066 and 1046. The 1074 offers 4 channels of gating with threshold, depth and release controls on each channel. The 1074, like the rest of the products in dbx 10 Series, is based on the legendary dbx V2 VCA and offers XLR inputs and outputs, and 1/4” side-chain input. In addition to an external key input per channel, the 1074 also has an internal filter that can be independently activated and controlled on a channel-per-channel basis. This filter allows the 1074 to not only clean up tracks, but gives you frequency selective control on each gate, to open exactly when you want it to. These features combined, make the 1074 an absolute must for those who require quad gating on applications including: Gating dry and percussive sounds such as snare drum and kick drum,gating sounds that have longer decay times such as cymbals and Pianos, gating hum or buzz from live instruments or recorded tracks or eliminating Headphone leakage into microphones. Gating instrument microphones to eliminate amplifier bleed. 

From the company that has been redefining the standard of signal processing for more than 30 years, dbx® Professional Products comes a bulletproof product that caters to the scrutinizing needs of those who require the precision noise gating capabilities. Once again, the engineering staff at dbx® Professional Products have taken technology that has been over three decades in the making and have created a product that is flexible, versatile and rock solid in construction design. The 1074ʼs independent channel design with key filtering capabilities make it the perfect tool for countless applications.

• Four independent channels of gating
• Independent key filtering
• Independent Threshold and Release controls
• Differentially balanced gold-plated XLR and 1/4" inputs and outputs
• True RMS level detection
• Stereo Coupling mode
• Switchable +4dBu or -10dBv operation per channel
