Operation; Adjusting Gain / Crossover; 2/4 Channel Switch; Subwoofer Input Switch - Rockford Fosgate PUNCH P1000X5D Manual Del Usuario

Operation

Adjusting Gain
1. Turn amplifier gains to minimum (counter-clockwise).
2. Turn the source unit volume up to 7/8 maximum (or when distortion
is just inaudible).
3. Slowly increase amplifier gain control until adequate volume is
achieved.
NOTE: Best signal to noise and dynamic range are realized with gain set to
minimum. For a more in depth setting procedure, contact Rockford Tech-
nical Support.
Adjusting Crossover Frequency
Do the following individually for each
channel.
Placing the crossover switch in the HP
position sets the amplifier to the High Pass mode,
enabling frequencies above the cut-off point to pass,
adjustable between 50-500Hz.
Placing the crossover switch in the AP position sets the amplifier to the All
Pass mode, preventing any crossover adjustment, allowing all frequencies
to pass.
Turn the crossover adjustment knob all the way down. With the system
playing, turn the crossover adjustment knob up slowly until the desired
crossover point is achieved.

2/4 Channel Switch

Setting this switch to the 2CH. position, switches the in-
puts to a 2-channel mode, allowing connection to only
the front inputs with a 4-channel output.
Output controls function the same as if the amplifier was
in 4-channel mode.
All "ACTIVE" inputs must have RCA jacks connected.
Switch in 2CH. position,"ACTIVE" - Front channel
inputs only.
Switch in 4CH. position,"ACTIVE" - All Front and Rear channel inputs.
NOTE: When connecting to the 4-Channel inputs, be sure to route both
front and rear RCA cables tightly together.

Subwoofer Input Switch

Setting this switch to the Front position, utilizes the front
inputs, allowing connection to only the front inputs with
a subwoofer output
Output controls function the same as if the amplifier was
in 5-channel mode.
All "ACTIVE" inputs must have RCA jacks connected.
10
Avoid setting amplifier gain high as noise and
distortion will greatly increase.

Switch in FRONT. position,"ACTIVE" - Front channel inputs only for sub
output. Switch in SUB position,"ACTIVE" - Sub inputs for sub output.
NOTE: When connecting to the 5-Channel inputs, be sure to route front,
rear and sub RCA cables tightly together.

Infrasonic Filter

The 20Hz 24dB/octave infrasonic filter limits the amount
of low frequency information going to the woofer.
NOTE: We recommend using the infrasonic filter when
using vented enclosures with this amplifier.

Variable Phase

Allows you to conveniently switch the output phase of the
amplifier between 0° and 180°. This has the same effect
as physically reversing the Positive (+) and Negative (-)

speaker wires.

Punch EQ

This works along with the crossover switch on the amplifier. When set to
Low-Pass (LP) operation, this is a variable Bass Boost. Set this to your
personal preference while listening to the system.
