YellowTec PUC Classic High Definition USB Audio Interface w/ SPDIF I/O and Analog Line I/O on D-TYPE

Connection
Yellowtec PUC is designed to operate as an Audio Converter at a USB port of your PC.
PUC draws its power supply from the PC USB port.
External supply is not needed, therefore a power input connector is not provided/

Audio ports
PUC provides analogue and digital audio ports.
The analogue ports are in the professional studio format and deliver superb audio
quality. The electronically balanced input and output circuitry can supply levels up
to +18dBu without loss when operated unbalanced. International and german level
standards are available.
In the digital domain high quality S/PDIF input and output ports with SRA
(Sample Rate Auto Sensing) are provided. PUC automatically selects the audio source.
If a digital audio signal is present at the digital input, this input will be selected.
(Only condition: the input signal must be in a format that PUC identifies as convertable.)
Otherwise the analogue inputs are selected.
The outputs, digital and analogue, are simultaneously active.
The headphones output with its own driver circuitry enables you to monitor audio
signals processed by PUC without the need of additional equipment.

Audio Options
Via GPI (control input ports) you can select 3 functions:
1. ZLM (Zero Latency Monitoring). When active, the analogue input signal is added
(via summing amp) to the analogue output signal. This function allows you to monitor
the input signal without latency time caused by audio processing in a PC.
2. BYP (Digital Bypass). Hereby you switch a digital input signal directly to the
digital output. Audio data coming from the PC are cut out.
3. INT LVL (International Level). When active, PUC is set up for international
analogue Level standards: i.e. ref. Lvl. +4dBu / max. Lvl. +18dBu.
