Rear Panel Operations and Connections
SPEAKER OUTPUTS –
Factor Electronics V series amplifiers provide 4
speaker level outputs for the V-430 and V-460 and one speaker level
output for the V-4120 and V-4240. Do not use more than one output
at a time. This could overload the amplifier.
Remove the terminal block connector and select from the
following chart.
C
– Common or negative --
4 ohm
– Connect to a direct-coupled loudspeaker (no transformer)
min impedance 4 ohms (V-430/ V-460 only)
25V
- Connect to 25V transformer coupled loudspeakers.
(V-430/ V-460 only)
70V
- Connect to 70V transformer coupled loudspeakers.
(V-430/V-460/V-4120/V-4240)
100V
- Connect to 100V transformer coupled loudspeakers.
(V-430/ V-460 only)
RECOMMENED SPEAKER WIRE
Always use good quality stranded copper wire.
Speaker outputs
4 ohm 12-16 AWG stranded copper unshielded
25V 16-18 AWG stranded copper unshielded
70V 16-18 AWG stranded copper unshielded
100V 16-18 AWG stranded copper unshielded
CAUTION:
Keep the speaker output guard on at all times. This will
help prevent shock and fire hazards. Ensure the power cord is not
connected to the AC outlet when making connections.
POWER CORD -
Connect the AC power cord to 110V AC outlets only.
Do not connect the power cord until all audio connections are made.
Serious damage may result if the amplifier is connected to line
voltages other than 110V AC.
FUSE - TYPE T6, 3al/250V -
Always use the correct fuse for
replacement. Failure to use the correct fuse or shorting the fuse could
result in fire and serious damage and void your warranty
.
300Hz HPF-
The 300 Hz High Pass Filter has no effect on the output signal in the UP
/ OFF position. When this switch is engaged in the DOWN / On position the
speaker output frequencies below 300 Hz will will rolled off at 12 dB per octave.
Use this switch when horn speakers are connected to the amplifier speaker outputs
to remove unwanted bass frequencies that could damage the horn speakers.
In normal operation keep the 300 Hz HPF in the UP / OFF position.
