Chipset & Features:

(as delivered in standard configuration)

---

• Inputs - 2 RCA & BNC (switchable)


• High Grade Input Pulse Transformer


• CS8414 Digital Receiver on IC socket (CS8412 can be fitted or DIR9001 on
  adapter board)


• High Grade 11.2896 MHz clock Oscillator for reclocking (44.1KHz source
  only)


• SAA7220 Digital Filter (can be bypassed for 1X sampling) on IC socket
  (can be removed)


• TDA1541A DAC (single) on IC socket (can be upgraded with crown/double
  crown TAD1541A)


• 4 pcs OPA604 I/V conversion and lowpass filter/output buffer on IC
  Sockets (upgrade with AD8610 and BUF04 or other options)


• Dual RCA Outputs (CMC Brand high grade sockets)


• High grade line output transformers on output pair B


• High Grade encapsulated 50VA torroidal mains transformer (115/230V
  universal worldwide primary windings)


• 8,800uF power supply capacitance in high grade Nichicon Japan capacitors
  


• 4,000uF power supply capacitance, Nichicon Japan Muse capacitors


• 6pcs LM317T Regulator


• 3pcs LM337T Regulator


• Analog stage power supply can be adjusted from ±5V to ±18V to suit
  the power supply requirements of any op-amp's used


• Extensive supply decoupling using Nichicon Muse bipolar capacitors and
  film bypass capacitors


• Includes top quality Gotham Cable Switzerland internal analog line
  output cables and silverplated copper & teflon true 75 Ohm impedance coaxial
  internal digital signal Cable

Technical Data

(all measured in 4X Oversampling Configuration without reclocking
and with standard analog stage and Output A (transformerless)
connected)

---

• Signal/Noise ratio: >95dB


• Output Voltage: > 2V RMS @ 0dbfs


• Output Impedance: < 220 Ohm


• Response: 20hz to 20k +-0.5db


• Output Polarity: Non inverting (correct polarity)


• Channel Separation: >85db


• Distortion: <0.002%


• Max Wordlength: 24Bit (DAC will accept 24 bit data, but will
  convert only the 16 most significant bits)


• Max Sample Rate: 96KHz with CS8414 fitted (1X operation), 48KHz
  in 4X operation, 192KHz can be processed by the DAC in 1X operation if a
  suitable receiver module is fitted (not supplied)


• Jitter Reduction: High-stability crystal-controlled re-clocking
  for all inputs (44.1KHz sample rate only)


• Input Connections: 2 input connectors (RCA and BNC) selectable via
  rear panel switch and D-Sub for I2S (option - not connected as
  standard)


• Output Connections: 2 pairs of output connectors (RCA), output
  transformer on pair B or op-amp on pair A


• Power Consumption: 100-135VAC or 200-270VAC 50/60hz 20W


• Dimensions: 440 (L) x 320(W)x100 (H)mm


• Weight: 10 kg (packed)

Alternative Configurations and Options

(included unless
noted otherwise)

---

• Operation with or without reclocking (via jumper configuration)


• Operation with 4 X oversampling digital filter or without digital filter
  (via jumper configuration)


• Single Op-Amp, inverting polarity output with NE5534 for experimenters
  (replacement PCB, fully assembled, plug & play)


• Operation with S/P-DIF direct input bypassing input switching and input
  transformer for purest sound quality (requires soldering - basic)


• Analog Stage Upgrade component pack (NOT INCLUDED - EXTRA COST OPTION)
  for standard output stage including AD8610 operational amplifiers, BUF04
  buffers, Elna Silmic output coupling capacitors and polystyrene analog
  filter capacitors; basically the best of the best available (requires some
  soldering - advanced)


• Blank PCB for conversion to Gemini (Twin) DAC Status (requires
  soldering, extra components and reconfiguration - highly advanced)


• I2S input on SUB-D 9-Pin connector bypassing internal digital receiver
  (requires soldering and reconfiguration and suitable source - highly
  advanced)
