Clarion APA5241 User Manual

Clarion APA524I
circuit design keeps AM RFI at low levels, so you won’t hear unwanted
noise when the level is cranked up. Protection circuits safeguard the
amplifier when overheating and speaker shorts or improper load
conditions occur. All connections and controls are on end panels and are
straightforward and easy to understand. We use gold-plated RCA and
barrier connectors to ensure the best electrical connection for your system.
Included are external automotive-type fuses that are easy to replace.
Amplifier Inputs/Controls/Power Indicator
The APA5241 ’s front panel (see Figure 2) has SPEAKER LEVEL INPUT
connections, 4-channel (RCA) INPUT jacks, GAIN controls for 4-channel
input level adjustments and summed input adjustment for channel 5, a
BASS EXTENDER gain control, a CHANNEL mode switch, a FILTER
FREQ control for selecting crossover filter frequencies, a FILTER mode
switch, and a POWER indicator.

APA5241. A reference chart (see detail on
right) shows which inputs are active for a
selected channel mode.
Low-Level/Speaker-Level Inputs
The APA5241’s gold-plated RCA input jacks, labeled CH 1 through CH 4,
provide connections for a low-level front/rear stereo source. Alternately,
the SPEAKER LEVEL INPUT connections can be used in installation
where the source unit’s RCA outputs are unavailable and direct connection
to speaker outputs is the only choice (see page 20 for wire codes).
Gain Controls
The GAIN CHI/2 and GAIN CH3/4 controls allows you to independently
set the nominal operating levels of the amplifier’s front and rear channels.
The GAIN CH5 control allows you to independently set the summed input
