INSTALLATION GUIDELINES
Connecting the GND (GROUND) screw terminal
Connecting a mixer or preamplifier may cause
excessive noise or hum in the amplifier output. To
prevent this, connect one end of a low-capacitance
shield wire to the amplifier's ground screw (on the
rear panel). Then connect the other end of this wire
to the ground terminal on the mixer or preamplifier
enclosure.
Input connections
These amplifiers accept a board range of input sources,
including Compact Disc (CD) players; Cassette, Reel-
to-Reel or other tape players; Radio Tuners; Equalizers;
Signal Processors.
Connecting a CD or tape player, or tuner
In a normal installation, one would use the RCA
JACKS for connecting a CD player, tape player or
tuner.
Connecting an equalizer or external signal
processor
Connect the processor's OUT to the amplifier's IN
connector.
Stereo or Mono Inputs (PA1000X/PA1800X)
The PA1000X and PA1800X can be operated in Stereo
or Mono mode, depending on the input source. If the
input signal is mono, connect the source via the LEFT
input only (also marked "MONO" on the back of
amplifier). Then slide the STEREO/MONO selector
switch to MONO and the signal will be routed through
both channels.
Speaker connections
You can connect 4 Ohm, 8 Ohm, or 16 Ohm speakers
to Channel A and/or Channel B of the amplifier. If you
connect two pairs of speakers, be sure to follow these
guidelines:
• Speakers which are connected to the same channel
are part of a pair, and must be of the same impedance.
• Speakers connected to different channels are NOT
part of a pair, and can be of different impedances.
1.Prepare the speaker wire by removing about 1 inch
of insulation from the end of speaker wire you intend
to connect to the amplifier. Then twist the exposed
wire to secure all the wire strands.
NOTE:Use 18-gauge speaker wire for lengths up to 25
feet; 16-gauge wire for lengths over 25 feet. It
is recommended that you use the shortest length
of wire possible.
2.Connect the speaker wire to the speaker's positive
and negative terminals.
NOTE:Most speaker terminals are either color-coded
or have a mark that indicates the terminal's
polarity. Usually positive terminals are red or
have a plus symbol (+), and negative terminals
are black or have a minus symbol (-).
3.Connect the speaker wires to the amplifier's left and
right speaker terminals according to the terminal
color polarity.
