The Voice Channel from ART is a single channel recording strip that features a tube based microphone preamp, a comprehensive dynamics section, a semi-parametric 4-band EQ and an output section that provides both analog and digital connectivity.
Microphone Preamp
- Class-A differential preamp optimized for low impedance microphones as well as line level signals
- The impedance of the front and rear XLR inputs is continuously variable for fine-tuning the preamp to a wide variety of microphones
- Selectable tube plate voltage
- Switchable phantom power
- Selectable 100Hz 6dB/8ve low-cut filter for removing rumble, and wind noise
- Switchable 20dB pad and phase invert switches
- Front panel DI provides a high impedance unbalanced input for instrument
Dynamics
- Consists of an above threshold Compressor/Limiter with De-esser, plus a selectable Expander/Gate
- Variable ratio control
- Variable attack and release controls
- De-esser control sets how much more the gain is reduced at high frequencies when using the compressor/limiter - commonly used for taking out sibilance
- De-esser frequency control selects which frequencies to reduce
- Gate has an intelligent detector with a fast attack and release, coupled with a program dependant hold
- Gain reduction LED meter
EQ
- 4-band semi-parametric equalizer
- EQ can be bypassed and also positioned before or after the dynamics section
- High and Low EQ bands are shelving type with a switch selectable turnover point
- The Mid bands can be continuously tuned over a 5-octave range
- +/-12dB boost on each band
Output
- Output level control provides gain or attenuation and affects the levels sent to the analog-to-digital converter, and to the balanced analog output jacks
- Mic preamp output provides a direct signal from the preamp and in conjunction with the insert input allows for insertion of external processing prior to the EQ and dynamics
- Signal processing can be added between the analog output of the Voice Channel and the "left" and "right" channels of the A/D converter by using the A/D main insert and the A/D CH2 insert respectively
- In ADAT mode, channels 1 and 2 are the "left" and "right" A/D outputs of the Voice Channel respectively. If the A/D insertion jacks are not being used, both channels 1 and 2 carry the same signal
- If the ADAT input is being used, channels 3 through 8 are passed through along with channels 1 and 2 of the Voice Channel
- Sample rate/dither knob selects the sample rate for the AES/EBU, S/PDIF and optical digital outputs
- Wordclock input and "thru" on BNC connectors
- USB 1.1 jack provides the output to a computer USB connection
- Analog and digital output meters
