ADC2 A/D Converter

The ADC2 is the successor of our renowned two channel ADC1-MK2 A/D Converter.

"The Weiss ADC2 has the ability to capture the highest level of detail while keeping the tonal integrity of any instrument the best that I have heard. The ADC2 is my favorite converter."

Helik Hadar (Engineer/Mixer - Herbie Hancock's Grammy Winning "River: The Joni Letters")

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 for PowerPC or Intel 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 converter’s 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.
