MONOPHONIC OUTPUT—CONNECTING TO
BARRIER STRIPS
When the NIC 2100 is to operate as a monophonic
amplifier, the two channels are combined to produce a
single 210 watt output. This chart lists the proper con-
nections and interconnections for monophonic opera-
tion.
If the
speaker
impedance
is:
2 ohms
4 ohms
Connect one speaker
lead to the screw
marked LEFT-COM
and the other to:
LEFT-4
LEFT-8
8 ohms LEFT-16
For constant voltage
25 volts
LEFT-8
Connect a
wire between:
LEFT-4 and
RIGHT-4
LEFT-8 and
RIGHT-8
LEFT-16 and
RIGHT-16
LEFT-8 and
RIGHT-8
When connected as above the MC 2100 operates as a
210 watt per channel monophonic amplifier.
STEREO OUTPUT—CONNECTING TO
THE OCTAL SOCKET
The octal socket marked OUTPUT can be used for all
of the output impedances and voltages. Connections
are made in the following fashion:
If the
impedance is:
Solder the left
channel leads
between:
4 ohms Pin 1 and 2
8 ohms Pin 1 and 3
16 ohms Pin 1 and 4
For constant voltage
25 volts Pin 1 and 3
Solder the right
Channel leads
between:
Pin 5 and 6
Pin 5 and 7
Pin 5 and 8
Pin 5 and 7
When connected as outlined the MC 2100 operates as
a 105 watt per channel stereo amplifier.
MONOPHONIC OUTPUT—CONNECTING
TO THE OCTAL SOCKET
If the
impedance is:
2 ohms
4 ohms
8 ohms
25 volts
CONNECT
2 and 6
3 and 7
4 and 8
4 and 8
Solder the
leads to:
1 and 2
1 and 3
1 and 4
1 and 4
When connected as outlined the MC 2100 operates as
a 210 watt monophonic amplifier.
AC POWER:
The power requirement for the MC2100 is 117 to 130
volt, 50/60 Hz. The amplifier will be turned on and off
if its power cord is plugged in one of the auxiliary AC
power outlets on the program source.
