The glass-plate amplifier is made of one PCB because of a minimal number of wires with connectors, Phono input, two line-level inputs (RCA), a Jack line input (3.5 mm) and a Bluetooth connection.

Exclusively quality parts and connectors are equipped on the board.

Bluebird Integra Mk.2 :

A three-channel radio-controlled remote control (volume up/down, input selection). Range of control is up to 50 metres

Phono: A passive RIAA supply generates the musical signal for the ideal sounding. The applied IC is developed particularly for this goal, its noise level and distortion is extremely low.

The 2+1 line inputs are optimised for the common CD, DVD players and devices operating via networks.

Bluetooth V4.1 + EDR – The Bluetooth system supports making phone calls

The engine based potmeter is a ALPS make
