2. Connection to REC OUT terminal (recording)

When the sound source from the various input devices is reproduced, which are connected to the PHONO or LINE terminals of this unit, setting the recording switch to on allows users to provide the REC OUT terminal with the signal. Connection between the REC OUT terminal of this unit and the line input terminals (LINE IN) of the recorder with pin plug cables is required for recording on the recorder. After the connection, you can enjoy listening to the sound from the speaker system and record the sound at the same time. These output signals for recording are not affected by the control functions such as the volume control and tone control functions.

When you need not toggle an input source to be recorded (especially when a recorder connected to the recorder output terminals is recording), do not operate this switch. Do not insert shortpin plugs into REC OUT. No sound is generated.

When a CD recorder, tape recorder, or other devices are connected, be aware that the playback sound volume becomes low or no sound is generated if the device extremely decreases the impedance of the line input terminals of the recorder or causes short-circuit on the line input terminals or if the recording switch is set to on.

How to connect PRE OUT/MAIN IN terminal

Either the pre-amplifier or main-amplifier can be separately used.

When the pre-amplifier or main-amplifier is separately used, set the separate switch on the front panel to on.

When-only-the-pre-amplifier-is-used,connect-the-PRE-OUT-terminal-of-this-unit-to-the-input-terminal-of-another-power-amplifier,and-when-only-the-main-amplifier-is-used,connect-the-MAIN-IN-terminal-of-this-unit-to-the-output-terminal-of-another-power-amplifier.

When this amplifier is used without separating between pre-amplifier and main-amplifier, set the separate switch on the front panel to off, or no sound is generated.

Do not insert shortpin plugs into PRE OUT. No sound is generated.
