The Buffalo32s DAC
The current round of pre-orders will begin shipping August 10th.
Highlights
Based on the ESS Sabre32 Reference (ES9018) DAC chip
Four DACs per channel ("Stereo Quad Balanced" mode)
High-precision, ultra-low-phase noise clock
Integrated reclocking
Direct DSD, I2S and S/PDIF inputs supporting up to 24-bit/192kHz
Integrated dual IVY-II current-to-voltage analog stages
Supports balanced and single-ended outputs from the same header
Optional through-hole resistors for customizing output voltage
All connections by direct or optional (included) terminal blocks
I2C header for remote uC interfacing
The Buffalo32s is the first DAC available based on the new ESS ES9018 Sabre32 DAC chip.
The Buffalo32s DAC module accepts direct S/PDIF, I2S and DSD data input formats. Analog outputs are balanced, and can be used as directly as single-ended outputs without separate conversion.
Standard balanced output is 4Vp-p, and single-ended is 2Vp-p. By adding optional through hole resistors, the output levels can be customized to meet your exact system requirements.
The Buffalo module requires two power supplies. The digital section requires 5-7.5VDC and the two analog I/V sections require a ±12 to ±15VDC supply. We offer a combination of the Buffalo32s
and our Low Current Dual Power Supply (LCDPS) and Low Current Bi-Polar Power Supply (LCBPS) below. Each supply requires it's own separate transformer. We recomend a 2 x 6-9V(15VA) transformer
for the digital section and a 15V+15V (15VA or greater) transformer for the analog I/V sections. Suitable transformers are available here.
