DAC DSD

Prototype version of DAC. DAC accepts PCM and DSD signals. The DSD signal from the input to the output is not converted, this is the native DSD. DAC allows you to select the digital signal transmission, you can change the real-time input signal from PCM to DSD and from DSD to PCM. It is also possible to select the sampling frequency: for PCM from 44.1 kHz to 384 kHz, for DSD 5.6 MHz and 11.2 MHz.

Important features:

• XLR and RCA lamp outputs, audio signal transmitted to outputs without capacitors and transformers
• Digital inputs: 1 USB (Amanero), 1 Toslink, 1 Coaxial

Specifications:

• Output tubes PCC88, 2 per channel
• Audio output level at 1 kHz: for RCA - 4 V, for XLR - 8 V (PCM mode)
• Audio output level at 1 kHz: for RCA - 2 V, for XLR - 4 V (DSD mode)
• Power consumption: 120 W
• Weight: 10 kg
• Dimensions: 33 x 7 x 25 cm

PRIMUS HYBRID

Hybrid stereo amplifier. Input stage based on PCC88 and 6N6 or 6N30 tubes, output stage on mosfet transistors, fully symmetrical audio track from input to push-pull output and pure class A. The amplifier has a solid-state protection on the speaker output, delayed speaker feedback and control. Remote control including: volume control, balance, change of inputs.

Important features:

• The use of mosfet transistors ensures proper operation with most loudspeakers

Specifications:
