Share This Post
The construction of this device is simple. The housing consists of two parts:
- Top enclosure cast from aluminum alloy, used to dissipate heat from audio amplifiers and as a frame for the main board
- Bottom enclosure stamped from SECC steel, used as a cover for the main board
The amplifier is based on two audio amplifier chips provided by NXP Semiconductors. One of chips generates an output power of 4x80 W(at 2 Ω) and the second –4x140 W (at 2 Ω). The sound is converted by a 2-channel 32-bit DAC (up to 192 kHz) and two 4-channel 24-bit ADCs (up to 192 kHz). The sound is processed by the SHARC Core audio processor provided by Analog Devices.
