Pioneer GM-5000T - Manual

Setting the Unit

Gain Control

If the sound level is too low, even when
the volume of the car stereo used along
with this power amplifier is turned up,
turn gain control on the front of the
power amplifier clockwise. If the sound
distorts when the volume is turned up,
turn the gain control counter-clockwise.

• When using with an RCA equipped car

stereo (standard output of 500 mV), set to
the NORMAL position. When using with
an RCA equipped Pioneer car stereo with
max. output of 4 V or more, adjust level to
match the car stereo output level.

Power Indicator

The power indicator lights when the
power is switched on.

Thank you for purchasing this PIONEER
product. Before attempting operation, be
sure to read this manual.

In case of trouble

When the unit does not operate properly,
contact your dealer or the nearest autho-
rized PIONEER Service Station.

CAUTION

Never replace the fuse with one of greater
value or rating than the original fuse. Use
of an improper fuse could result in over-
heating and smoke and could cause dam-
age to the product and injury including
burns.

CAUTION

Do NOT install or use your Pioneer ampli-
fier by wiring speakers rated at 4 Ohm (or
lower) in parallel to achieve a 2 Ohm (or
lower) bridged mode (Diagram B).
Amplifier damage, smoke, and overheating
could result from improper bridging. The
amplifier surface could also become hot to
the touch and minor burns could result.
To properly install or use a bridged mode
for a two-channel amplifier and achieve a 4

Ω

load, wire two 8

Ω

speakers in parallel

with Left + and Right - (Diagram A) or use
a single 4

Ω

speaker. For a four-channel

amplifier, follow the speaker output con-
nection diagram for bridging as shown on
the back of your amplifier, and wire two 8

Ω

speakers in parallel to achieve a 4

Ω

load

or use a single 4

Ω

speaker per channel.

If you have any questions or concerns,
please contact your local authorized
Pioneer dealer or call Pioneer customer
service.

WARNING

• Always use the special red battery and ground

wire [RD-223], which is sold separately. Connect
the battery wire directly to the car battery positive
terminal (+) and the ground wire to the car body.

• Do not touch the amplifier with wet hands.

Otherwise you may get an electric shock. Also, do
not touch the amplifier when it is wet.

• For traffic safety and to maintain safe driving

conditions, keep the volume low enough so that
you can still hear normal traffic sound.

• Check the connections of the power supply and

speakers if the fuse of the separately sold battery
wire or the amplifier fuse blows. Detect the cause
and solve the problem, then replace the fuse with
another one of the same size and rating.

• To prevent malfunction of the amplifier and

speakers, the protective circuit will cut the power
supply to the amplifier (sound will stop) when an
abnormal condition occurs. In such a case, switch
the power to the system OFF and check the
connection of the power supply and speakers.
Detect the cause and solve the problem.

• Contact the dealer if you cannot detect the cause.
• To prevent an electric shock or short-circuit

during connection and installation, be sure to
disconnect the negative (–) terminal of the battery
beforehand.

• Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.
