VOICECHANNEL

ART

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 signalsThe impedance of the front and rear XLR inputs is continuously variable for fine-tuning the preamp to a wide variety of microphonesSelectable tube plate voltageSwitchable phantom powerSelectable 100Hz 6dB/8ve low-cut filter for removing rumble, and wind noiseSwitchable 20dB pad and phase invert switchesFront panel DI provides a high impedance unbalanced input for instrumentDynamics Consists of an above threshold Compressor/Limiter with De-esser, plus a selectable Expander/GateVariable ratio controlVariable attack and release controlsDe-esser control sets how much more the gain is reduced at high frequencies when using the compressor/limiter - commonly used for taking out sibilanceDe-esser frequency control selects which frequencies to reduceGate has an intelligent detector with a fast attack and release, coupled with a program dependant holdGain reduction LED meterEQ 4-band semi-parametric equalizerEQ can be bypassed and also positioned before or after the dynamics sectionHigh and Low EQ bands are shelving type with a switch selectable turnover pointThe Mid bands can be continuously tuned over a 5-octave range+/-12dB boost on each bandOutput Output level control provides gain or attenuation and affects the levels sent to the analog-to-digital converter, and to the balanced analog output jacksMic 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 dynamicsSignal 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 respectivelyIn 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 signalIf the ADAT input is being used, channels 3 through 8 are passed through along with channels 1 and 2 of the Voice ChannelSample rate/dither knob selects the sample rate for the AES/EBU, S/PDIF and optical digital outputsWordclock input and "thru" on BNC connectorsUSB 1.1 jack provides the output to a computer USB connectionAnalog and digital output meters
