FIRE PHOENIX DAC-05 OPA2604 CS3310 CS4398 192K/24BIT USB DAC Headphone Amplifier


OPT & COA is used with CIRRUS LOGIC, and it is compatible with the high-end digital tone source from current market. There is an external USB receiver and a 24bit separate DAC decoder.DAC is equal to a high-end external sound card plus headphone amplifier once the USB connected to a computer. The control part of the machine is of abilities of MCU individually adjusting, digital volume and power on delay. Volume control is made my using a top-level IC CS3310.Balanced filter and operational amplifier are using OPA2604.Overall sound quality can match in excellence with ten thousand –level CD’s.

Power supply unit: ±15V being used in voltage-stabilizing during signal processing ,TL431 is for digital processing, control the individual +5V power supply,which can provide more stable performance and pure sound.

Input-digital input:

  • COA, OPT and USB, each for a group. Note: the ports are gold plated.
  • Multiple Sample rates: 32K-MAX192K/24BIT(for USB input: only support 16bit/44.1K and 48K)
