CONNECTING THE SPEAKERS
Speaker Terminals
The rear panel of the CJ-V99/CJ-V77 is equipped with ter-
minals (EXTERNAL SPEAKERS] for connecting the exter-
nal speakers.
CAUTION
THIS INSTALLATION SHOULD BE MADE BY QUALI-
FIED SERVICE PERSONNEL AND SHOULD CONFORM
TO ALL LOCAL CODES.
(1) Short terminal
(2) 4 Q to 16 Q terminal
(3} 2 Q to 4.Q terminal
(4) COMMON GND terminal
(5) 70.7CV terminal
The 2 2 to 4.Q and the 4Q to 16 2 terminals are calfed the
low impedance
terminals, and the
70.7CV terminal is
called the high impedance terminal.
1. Low
Impedance
Connection
and
High
Im-
pedance Connection
{1) Low Impedance Connection
Used when sound quality is of greatest importance.
Connects 2 to 4 Q or 4 to 16.Q speakers.
The 4 to 16 Q terminal directly connects the amplifier out-
put, resulting in high quality sound.
For speakers connected
in parallel, the impedance. is
decreased, and the number of connected speakers is limit-
ed.
{See 4, Connecting Low impedance Terminais.}
The longer the distance between the amplifier and speak-
ers, the speaker input decreases due to speaker cable
resistance.
(2) High Impedance Connection
To prevent speaker input reduction caused by the speaker
cable resistance, a transformer is installed in the speaker
to increase the impedance
and increase
the voltage for
transmitting the amplifier output.
(See 5. Connecting the High Impedance Terminal.)
(For CJ-V99/CJ-V77,
the amplifier output voltage is in-
creased to 70.7 V.}
Using the high impedance connection, many speakers can
be connected.
{The transformer impedance is changed according to the
number of connected speakers.}
The high impedance connection is also used to prevent
power loss caused by a long speaker cable.
2. Switching the Amplifier
CJ-V99/CJ-V77 is equipped with 30 W and 100 W ampiifi-
ers.
The following two modes can be switched alternatively:
100 W for internal speakers
30 W for external output terminal
30 W for internal speakers
100 W for external output terminal
The output can be switched by changing the connector on
the left side of the amplifier unit front panel.
When delivered, the internal speaker and external output
terminal are set for 100 W and 30 W, respectivefy (the ter-
minal and connector are connected using the same color).
Change the connector.
3. Setting the Short Bar
Speakers are connected to the connection terminal and
the COMMON
GND terminal,
Remove the short bar between pins 1 and 2 to use the 4 to
16 Q terminal.
Set the short
bar between
pins 1 and
2 when
using
another terminal (2 to 4 Q terminal or high impedance
70.7CV terminal}.
CAUTION :
Only one of the 4to 16.2, 2 to 42, and 70,7CV terminals can be
used at one time.
Short bar setting for connecting to
the 2 to 4. Q or 70,7C¥ terminal.
eRe
Short bar setting for connecting to
the 4 to 16 Q tenninal.
[Example]
Speakers are connected to the 2 to 4 @ terminal.
