Analog audio input terminals Line, Bias switch

AAnalog audio input terminals [LINE IN]

Used for the input of analog 2-channel audio signals. Connect these terminals to a Super Audio CD player (Example: SA-10, X-01SE, etc), DVD player, cassette tape deck, tuner, etc. using commercially available XLR or RCA audio cables. Connect the unit’s R terminal to the player’s R terminal, and the unit’s L terminal to the player’s L terminal.

To use line input, set the LINE IN/DIRECT IN switch to “LINE IN”. Select an input with the INPUT button on the front panel and adjust the volume with the VOLUME control knob. The remote control can also be used in this “LINE IN” (Integrated amplifier), setting.

BBIAS switch

It is possible to select the bias current for the KT-88 output tube with this switch.

A bias current is a current that continues to flow to a tube when there is no input signal. Depending on preset values, a bias current can cause distortions in sound quality. The standard setting is B. The bias current will decrease when set to A, and depending on the compatibility between the tube and the system it is connected to, sound quality may become slightly more delicate. There is a tendency to use this setting when playing classical music.

Depending on the accompanying machine, changes can be difficult to detect on the A setting. Please set to B if you cannot detect audible changes on the A setting.
