Your speaker system needs to meet the following requirements.
If speakers that do not meet the following requirements are
used, the amplifier protective circuit may trip, and sounds will
not playback correctly. In certain cases, damage may also be
caused to the amplifier and speaker system.
• If using 1 set of speakers, total speaker impedance must be
4 Ω or more.
• If using 2 sets of speakers, total speaker impedance must
be 8 Ω or more.
• When using the speaker system in BTL mode, use a speaker
system that has an impedance of 8 Ω or higher.
Notes:
• To prevent damage to circuitry, do not let the bare speaker
wires touch each other and do not let them touch any metal
part of this unit.
• Do not touch the speaker terminals when the power is on.
It may cause you to receive an electric shocks.
• Do not connect more than one speaker cable to one
speaker terminal. Doing so may damage this unit.
• Be sure to connect the positive and negative cables for
the speaker properly. If they are miss-connected, the
signal phase will be reversed and the signal quality will
be corrupted.
