Tech Specs
Check out some brief technical specification. If we had any class, we’d have letterpressed these with “From the bench of Jens Jungkurth” gold foil embossed, but we’re fresh out of class, so here you have it, down and dirty:

O/P = 80 Ω
BUSS = 7.5k Ω
Mic Input: Transformer balanced
Line Input: Transformer balanced
1/4″ Input: Unbalanced
Line Output: Transformer balanced
Buss Output: Transformer isolated, unbalanced
Mic Input Mode*
Nominally 900 Ω transformer balanced, floating
Gain adjustable from +21 to +65 in 7 steps
Maximum input 0 dBu for %1 THD+N @ 1kHz
Line Input Mode*
Nominally 12,000 Ω transformer balanced, floating
Gain adjustable from -6 to +15 in 5 steps
Maximum input +27dBu to produce max output condition (below)
*Mic and Line input modes can be used interchangeably for loud mics and quiet lines, or to experiment with distortion and impedance effects. 48V phantom power can be engaged regardless of the mic/line or gain settings.

The AwTAC Channel Amplifier is an analog audio signal processor conforming to the industry standard API™ 500 Series modular form-factor. It was designed according to API™ VPR Alliance specifications, and will thus install in any API™ or compatible 500 Series enclosure having two or more conjoined module slots. Such an enclosure, typically called “lunchbox” or “rack”, is required to operate an Awesome EQ, providing the necessary DC power and rear panel input/output connectors. While we at AwTAC™ have found the Purple Audio Sweet Ten Rack, a heavy-duty 10-slot 3RU enclosure which houses up to five Channel Amplifiers to be our favorite sounding rack, to the best of our knowledge at the time of writing the following third-party 500 Series enclosures should also suffice.
- Purple Audio Sweet Ten 10-slot rack with built-in power supply (5 AwEQ)
- API 500-6B 6-slot lunchbox® with built-in power supply (holds 3 AwEQ)
- API 500VPR 10-slot rack with API L200PS external power supply (5 AwEQ)
- Atlas Pro Audio Revolver 2-slot rack with built-in power supply (1 AwEQ)
- BAE Audio 11-slot rack with external power supply (5 AwEQ)
- BAE Audio 6-slot rack with external power supply (3 AwEQ)
- BAE Audio 6-slot lunchbox with external power supply (3 AwEQ)
- BAE DLB Dual-Channel Desktop 500 Series Lunchbox
- Radial Engineering Workhorse 8-slot rack with external power supply (4 AwEQ)
- Radial Engineering Workhorse Cube
- SPL RackPack 500 4-slot rack with external power supply (2 AwEQ)
- Tonelux V4 Roadster 4-slot lunchbox with built-in power supply (2 AwEQ)
Dimensions: 5.25″ x 3″ x 6″ (h x w x d, inches)
Weight: 2 lbs
Power Requirements: ±86mA @ ±16VDC
+ 4mA @ +48VDC (Only if using phantom-powered microphones)
