• Stereo Connections:
When you wish to use the unit as a stereo
amplifier, stereo connections are used.
The speakers to be connected should
have an impedance of 2Ω or greater.
When multiple speakers are to be
connected, ensure that the combined
impedance is 2Ω or greater for each
channel.
• Bridged Connections:
When you wish to use the unit as a high-
output monaural amplifier, bridged
connections are used. (Make connections
to the LEFT channel 9 and the RIGHT
channel · SPEAKER OUTPUT terminals.)
The speakers to be connected should
have an impedance of 4Ω or greater.
When multiple speakers are to be
connected, ensure that the combined
impedance is 4Ω or greater.
The rated input of the speakers should be no
less than the maximum output of the
amplifier. Otherwise malfunction may result.
^ RCA cable ground lead terminal
When using an RCA cable with a ground
lead attached, connect the ground lead to
this terminal.
& LINE IN terminal
* LINE OUT terminal
The signal that’s input from the line input
terminal is output.
$ Power control terminal
Controls the unit ON/OFF.
Controls the unit power. Be sure to connect it
with all the systems.
( EXT.AMP.CONT. (external
amplifier control) terminal
Controls the B.M.S. Only Kenwood center
unit models sold in 1999 or later with a
"EXT.CONT."/"EXT.AMP.CONT." wire
attached can be used.
Also, a maximum of 3 power amplifiers can
be operated at the same time.
There are cases when operation may not be
possible due to wiring wire type and length.
