Complete Bi-Amp Connection
Enhance connection 2, by having one more control Amp. SC-
7S1. This is a Complete Bi-Amp connection which separates
Mid / High signal and Low signal from the Pre-Amp section.
In this event, the SC-7S1 is using Monaural Amps. And sepa-
rate Left/Right channels from the output terminal of CD players.
As a result, influences between L channel and R channel Mid /
High signal and Low signal will be eliminated.
A maximum of 6 SC-7S1s, can be connected to each other,
via remote cables.
Caution
In the event of setting the mode switch as <Bi-Amp>,
B channel input terminals can’t be used.

Balanced terminal
ቢ The balanced output connector uses a XLR connector.
ባ The XLR connector is internally wired in either of the fol-
lowing two systems.
1. USA system (Pin 2 = COLD, Pin 3 = HOT)
2. European system (Pin 2 = HOT, Pin 3 = COLD)
ቤ The MA-9S1 uses the USA system of 1.
When a preamp or main amplifier adopting the European
system is connected using a cable with XLR balanced
connectors, the reproduced signal may be inverted of
phase.
In this case, correct the wiring of the one of the XLR con-
nectors on the extremities of the cable to the USA system
by exchanging the connections of pins 2 and 3. This will
make it possible to play the signal with the correct phase.
This connection can have options i.e. You may connect the units using either balanced or unbalanced
cables. But, you have to use the same cables per SC 7S1.
