The Weiss ADC2 is the successor of our renowned two channel ADC1-MK2 A/D Converter.
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. (FireWire option not yet implemented).
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 6dB 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.

"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")
"The ADC2 is a sophisticated, audiophile-quality converter with a musical soul." Alan Silverman, Pro Audio Review, Sept 2006. Read the full review
"Well, nothing but good things to report from today's lute session. The ADC2 was simply superior in every way with my lute players, and in every way extended the experience of how good digitally recorded sound can sound. This is it -- the converter I want to invest in and make fabulous recordings with. What a great unit -- I'm just so impressed with the sound quality." - Douglas Thompson, Burnsville, USA
"I have finally listened to your ADC2 in all sampling rates. I experienced what I expected. This is the best A/D converter that I have ever heard. Not only does it sound analog on 24/176,4, (I cannot hear any difference in A/B comparison from my analog tapes), it also sounds better than anything I know of down to 16/44.1, with the POW-R dither of course. (I prefer dither no 2). (There is of course a difference at 44.1 from the analog tapes , but it is smaller here than anything that I have heard before). Great!" - Mats Hellberg, Hellberg Ljud AB, Sweden
