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 impedance and capacitance, degrading the sound quality of high frequencies.
●Use left and right speaker cables that have the same length.
How to connect speaker cables
Use commercially-available speaker cables to connect the + terminal of the unit to the + terminal of the speaker and the - terminal of the unit to the - terminal of the speaker.
●Use speakers with at least 4 Ω impedance.
- If the exposed tip of the core wire of a speaker cable contacts another cord or terminal, a short could occur.
Never allow a speaker cable to short.
- Do not connect more than one amplifier to a speaker.
- Do not bundle connecting cables with power cords. Doing so could cause noise.
The power plug should always be disconnected when connecting speaker cables.
When using banana plugs
Insert the plug into the opening on the front of the terminal.
- Keep the cap tightened when in use.
- Carefully read the instructions for the banana plugs that you are using.
Notice about 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 lugs. If a black cap should become separated from its terminal, return it to its original position.
When using bare wires
Loosen the cap, insert the core wire from above and tighten the cap.
●The insertion hole faces up.
