Pure Class-A operation
Pre - and power amp section features
- This Bi-Amping possible or involvement in an AV System
the Rec Out selector
Backlit display for:
- Monitor indicator: Lights up when the monitor switch is in the On Position
- power display: The instrument to show the level in decibels and are illuminated when the amplifier is turned on
- Subsonic indicator: Lights when the Subsonic filter switch is turned on
- Mono indicator: Lights when the mono switch is activated
  - notes: Subsonic, Mono and Loudness can be achieved only with the help of the supplied remote control (RA-17A) is connected.
- Standby indicator: Lights up when the mains plug is connected to a wall socket and the power switch is in the off position
- Loudness Indicator: Lights up when the loudness switch is activated
- Line Direct Indicator: Lights up when the Line Straight switch is activated
- Seperately Indicator: Lights up when the switch for disconnecting the preamp and power amplifier is activated
- RCA terminal with 18 mm center distance
  - The introduction of RCA input and output terminals with 18 mm center distance allows the use of even high-quality connection cables with large plugs
