A 3-channel power amplifier developed for surround sound reproduction.

Four power transistors of Pc150W are used for each channel.
It can extract peak current of approximately 30A, and powerful sound reproduction is possible by driving the speaker powerfully.

The amplifier circuit has a completely discrete configuration. All components such as the power transformer and the power radiator are mounted independently on each channel to eliminate interference between each channel.
A single-package type differential FET with excellent DC (direct current) temperature characteristics is adopted in order to suppress degradation due to temperature effects, and an output DC voltage of less than 1 mV is achieved by precise tuning for each channel.

The chassis is made of copper-plated steel sheet, which has excellent shielding and damping properties. This reduces mutual interference and eliminates the influence of external noise and vibration on sound quality.

Drawing on the data obtained in the development of the S series, we use only capacitors that have passed strict listening tests when selecting custom capacitors, OFC wiring materials, film capacitors and resistors.

By connecting the remote cable to the AV control amplifier AVP-A1, power ON/OFF can be performed using the remote control of AVP-A1.

The design is unified with DENON's high-end component series.
