Connecting speakers

Notes about speaker cables

• Use commercially-available speaker cables to connect the speakers.
• Use the shortest speaker cables possible. The longer the cable, the greater the resistance value and the more that damping performance is reduced. Moreover, length also increases inductance and capacitance, degrading the sound quality of high frequencies.
• Use left and right speaker cables that have the same length.
  Precautions when connecting speakers
• Connect the power plugs after all connections have been made.
• Carefully read the manuals of the devices that you are connecting and follow their instructions when making connections.
• When the left and right grounds are shared in a subwoofer with a built-in amplifier, for example, use might not be possible depending on connection conditions.

ATTENTION

• This unit supports speakers that have a nominal impedance of 4 Ω – 8 Ω. If speakers with lower impedance ratings are used, the protection circuit could operate, causing the sound output to stop. In some cases, their use could even cause damage to this unit or the speakers.
• This unit’s red terminal is positive (¥) and its black terminal is negative (^). Generally, the ¥ wire of the speaker cable is marked to distinguish it from the ^ wire of the cable. Connect the marked wire to the red ¥ terminal and the unmarked wire to the black ^ terminal.
• If the exposed end of a core wire in a speaker cable contacts another cable or terminal, a short could occur.
• Never allow speaker cables to cause a short.
• To prevent hum and noise, avoid bundling the cables together with the AC power cord or other cables.

How to connect speakers
Using bare speaker wires

1. Remove about one centimeter (1/2″) of insulation from the ends of the speaker cables and twist the core wires well.
2. Turn the terminal caps counterclockwise to loosen them.
3. Insert the wires into the holes in the terminal posts and turn the terminal caps clockwise to securely connect them.
   Connect them so that the wire insulation is not touching the terminal.
4. Confirm that the cables are fastened securely by gently pulling them.

Using spade connectors

Insert the connectors between the caps and bases of the terminals.
Then, tighten the caps securely.

• When connecting speakers with spade connectors, they should have inside diameters of at least 8 mm.

Using banana plugs
Connection is also possible using commercially-available banana plugs. First, connect the banana plugs to the speaker cables and then connect the plugs to the terminals.

• Keep the caps tightened when in use.
• Carefully read the instructions for the banana plugs that you are using.

ATTENTION
Notice the European model
In accordance with European safety regulations, connecting banana plugs to speaker terminals is not allowed on European models.
The holes into which banana plugs could be inserted have been covered with black caps. Connect speakers using bare wires or spade connectors.
If a black cap should become separated from its terminal, return it to its original position.

Connections

CAUTION
This unit does not have a volume adjustment function. Connect this unit to a preamplifier or another device such as a DAC that has a preamplifier function, and use that device to adjust the volume. If you connect this unit to a device that cannot be used to adjust the output volume, you will not be able to adjust the volume during playback. The sound might be output from the speakers at a very loud volume, which could harm hearing or damage equipment.
The use of this unit’s two built-in amplifier channels depends on the OUTPUT MODE switch setting. Connection examples for each mode are provided below.

Complete all other connections before setting the STANDBY/ON switch to ON.

• Carefully read the manuals of the devices that you are connecting and follow their instructions when making connections.
• do not bundle connecting cables with power cords. Doing so could cause noise.
• Connect all plugs completely.

Using STEREO output mode

Set the OUTPUT MODE switch to STEREO.
Connection example

Using BI-AMP output mode
This unit can be used as a mono bi-amplifier.
Set the OUTPUT MODE switches on the units for the L and R channels to BI-AMP.
In BI-AMP mode, use two of these units for stereo playback.
What is the bi-amp connection?
This method operates amplifiers independently for low-frequency and high-frequency speaker units.
NOTE

• Sound input through the analog audio INPUTS L connectors will be output from both the L and R SPEAKER terminals.

ATTENTION

• Bi-amplification is not possible with speakers that do not have both low-frequency (LF) and high-frequency (HF) connectors.
• When using bi-amp connections, remove speaker terminal links and disconnect the connections between speaker ¥ connectors and between ^ connectors.
• Do not connect anything to the unit’s analog audio INPUTS R connectors.
  Doing so could result in damage.
