Setup and connection

Connecting Speakers

(Note) Speaker Impedance

Connect speakers with 4 ≠ to 16 ≠ impedance.
Setup: You have to change the setting on this unit if any of the connected speakers have 4 ≠ or more to less than 8 ≠ impedance. Change the speaker impedance setting to 4 ≠. (p10)

Connect the Speaker Cables

Make correct connection between the unit’s jacks and speaker’s jacks (+ side to + side, and – side to – side) for each channel. If the connection is wrong, a bass sound will not be reproduced properly due to reverse phase. Twist the wires exposed from the tip of the speaker cable so that the wires do not stick out of the speaker terminal when connecting. If the exposed wires touch the rear panel, or the + side and – side wires touch each other, the protection circuit will be activated.

Preparations

Connecting players (LINE IN connection)

Analog Audio Cable

Connect a playback device with an analog audio cable.

Connecting players (Turntable connection)

Analog Audio Cable

You can connect a turntable that has an MM-type cartridge to the PHONO jack. Use an analog audio cable to connect a turntable.
If the turntable has a ground wire, connect it to the SIGNAL GND terminal. With some turntables, connecting the ground wire may cause hum, in which case it should be disconnected.

If the turntable has a built-in audio equalizer, connect it to an LINE IN jack other than the PHONO jack. Also, if the turntable uses an MC type cartridge, install an audio equalizer compatible with the MC type cartridge between the unit and the turntable, then connect to any LINE IN jack other than the PHONO jack.

Troubleshooting

Before starting the procedure

Problems may be solved by simply turning the power on/off or disconnecting/connecting the power cord, which is easier than working on the connection, setting and operating procedure. Try the simple measures on both the unit and the connected device. After reconnecting, turn off and on the unit and the connected device.

  • This unit contains a micro PC for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least 5 seconds, and then plug it back in.
  • We are not responsible for reparations for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the material will be recorded correctly.

Resetting the unit (this resets the unit settings to the default)
