BENCHMARK ANALOG INPUT STAGES
The ADC16 features 16-channels of transformerless balanced analog inputs. The analog front-end continues Benchmark’s tradition of exceptionally pristine, award-winning analog circuitry – a legacy that dates back to the early 1980’s.
Each channel of analog input has a gain control (via a trim-pot) that has a 20 dB range. At 0 dB of gain, it can accept 28 dBu at the input without clipping. At max-gain, an 8 dB input-signal will drive the converters to full-scale.
ROUTABLE DIGITAL OUTPUTS
The ADC16 features three separate 16-channel output groups:
Balanced AES/EBU (16 channels at all sample rates);
Coaxial AES (16 channels at all sample rates);
Optical (AES or ADAT) (16 channels at all sample rates and formats);
There are two sources available for each output group:
A/D output (16 channels);
DAW return (16 channels) – if equipped with optional Firewire card
The control panel allows the assignment the source groups (A/D or DAW) to the output groups (AES, Coaxial, or Optical). This is very useful when the ADC16 is used in a studio with an analog console. The digital audio from the A/D chips can be sent directly to the digital outputs to a multichannel D/A to feed the console – completely bypassing the DAW while tracking. This reduces latency and DAW artifacts in real-time monitoring. At a press of a button, the return channels from the DAW can be routed to the same outputs for mixing.
16-CHANNEL METER BRIDGE
The ADC16 features 9-segment meters for each channel. These meters are single-sample accurate, so that even the shortest peaks are registered. The meters can be set to display in 6 dB increments (48 dB range) or 1 dB increments (20 dB range). In both cases, the meters can be put in ‘peak-hold’ mode, which will hold the highest-valued sample until the ‘peak-hold’ mode is reset.
