Step 1. Connecting speakers
For high-impedance connection (240 W × 1ch)
1.
Set SPEAKER SELECT to HIZ.
Set the output voltage to 70V or 100V according to the
setup in use.
NOTE
When using a high-impedance connection, it will
operate with output voltage of 100V or 70V.
100V is usual in Japan and Europe, while 70V is usual
in the USA.
Since it has less voltage drop than 70V, 100V is superior
for long-distance transmission.
2.
Set HPF (high-pass filter) to ON and OUTPUT to MONO.
ATTENTION
Always set HPF to ON because a speaker transformer
could become saturated and the protective circuit of
this unit could be activated.
NOTE
If OUTPUT is set to STEREO during high-impedance
connection, only sound from the L channel will be output
from the speaker output. Always set it to MONO.
3.
Connect to the SPEAKER OUT 70V/100V + and – terminals.
Use the included 5.08mm pitch (2pin) Euroblock for
connection.
ATTENTION
Do not exceed 240 W total for the rated input of the
connected speakers.
For low-impedance connection (120W × 2ch)
1.
Set SPEAKER SELECT to 4Ω or 8Ω to match the connected
speakers.
2.
Set OUTPUT to STEREO or MONO to select the output
format. When MONO is selected, the same sound (L+R)
will be output from both left and right.
3.
Connect to the SPEAKER OUT 4Ω/8Ω L/R + and – terminals.
Use the included 5.08mm pitch (4pin) Euroblock for
connection.
ATTENTION
o When connecting multiple speakers, be sure that
the composite impedance equals or exceeds the
impedance set on this unit.
o Do not connect low-impedance speakers to the
high-impedance terminals.
