Weiss ADC2

The ADC2 is the successor of our renowned two channel ADC1-MK2 A/D Converter. NEW: FIREWIRE option now available! The firewire option is a PCB which plugs into the main board of the ADC2. It supports bidirectional transmission: - analog or digital in from the ADC2 to the computer - from the computer to the ADC2, out on the S/PDIF connector on the back. All sampling rates are supported. There are drivers for Windows and PowerPC based MACs available.

The ADC2 uses state of the art A/D chips in our proven ?correlation technique? configuration, which lowers converter imperfections. The analog input stages are kept balanced from the input connectors throughout to the converter chips. A high quality microphone preamplifier is built in as a standard feature. Supported sampling frequencies are 44.1, 48, 88.2, 96, 176.4 and 192 kHz. Output formats are AES/EBU in one or two wire technique, S/PDIF as well as Firewire for a direct connection to computers. Synchronization can be internal or external through AES/EBU or BNC (Wordclock).

The built in digital peak limiter allows for setting a generous headroom on the analog inputs and still get a full scale signal at the converterΆs output. A large bar graph shows the level to the A/D input, the output level and the gain reduction in the aforementioned Limiter. The output wordlength can be reduced from 24 to 16 bits with the built in POW-R dithering. It is even possible to have one output running at 24 bits and another one at 16 bits. This feature comes handy when a safety copy to e.g. a DAT has to be made.

 The analog input sensitivity can be set in 1dB steps via a relais controlled attenuator. An additional gain control is implemented in the DSP chip in the digital domain. Both channel 1 and channel 2 are fully independent, except for the sampling rate and for the dither settings. The AES/EBU sync input can be used as a digital audio input. This allows to limit and / or dither digital audio signals. The peak hold feature can be used to monitor a transfer and check for overloads which may have occured.
