Polk Audio C500.1 MonoBlock Amplifier

Allows Polk/Momo Amplifiers to Deliver More Instantaneous Power Peaks, Easily Driving Your Speakers During Musical Peaks.

All Carbon Series Amplifier Models Feature:

• Polk’s Maximum Dynamic Headroom (MDH) Power Supply allows Polk/MOMO Amplifiers to deliver more instantaneous power peaks, easily driving your speakers during musical peaks. Get “max headroom” (!) and more power for low impedance loads.
• Each model features fully adjustable electronic crossovers to power any install using any speakers on the market.
• Each model also features the exclusive Polk/MOMO Pre-EQ Switch, which optimizes the crossovers for use with Polk/MOMO Ultra High Performance Speakers and Subwoofers so you can take high performance to whole new level.
• 5-Way Smart System Protection (SSP) circuits: Power and Ground-Reversal Protection, Thermal and Short Protection, Current Overdraw and Low Impedance Protection circuits with auto- Standby Mode ensure safety, reliability and durability.
• Hideaway Cover Plate conceals the wiring and the “Set It Once” user-adjustable controls for clean-looking, fiddle-free installs.
• Polk Performance Certificate attests to each individual amp’s Power Rating, and serial number.
• High-density split-dome convection heat sinks with more surface area than standard fins for extreme heat dissipation and a long, reliable life of high amplification. No need for noisy fans.
• High damping factor improves driver control for tighter, punchier bass.
• Subsonic Filter (15Hz@24dB/octave) for an extra level of speaker protection.
• Remote Subwoofer Level Control available on all models (a stock feature on the mono sub amp).
• Power, Thermal and Short Protection LEDs easily visible on top plate.
• Gold-Plated Screw-Down Capture Terminals for the most secure connections.
• Small footprints for compact installs. Removable End Caps for even smaller footprints: big power in small packages.

Detailed Adjustments for the Amp Panel

REMOTE BASS GAIN MODULE JACK
Accepts telephone jack input connection from the remote bass gain module. Set GAIN (8) to max when using the remote.

LOW PASS FREQUENCY ADJUSTMENT
Choose the frequency at which you want to roll off the low frequencies in your system. Adjustable between 30 and 200Hz.

FREQUENCY SLOPE TOGGLE
The crossover frequency adjustment (also called a Low Pass Filter) filters out frequencies that you don’t want the speaker to reproduce. In this case it filters out the midrange and high frequencies from the subwoofer. If it is set too high, you’ll hear voices and other midrange sounds coming from the subwoofer and the bass will seem to come only from the rear of the vehicle. If it is set too low, you'll miss the “kidney punch” kick of the mid- bass. Set the control to 80Hz – 120Hz and adjust it by year from there.

BASS BOOST FREQUENCY
Set this control lower to get more volume of deep “grunt” bass, set it higher to get more “kidney punch” kick. In most systems right setting will fall somewhere between 30Hz and 100Hz.

BASS BOOST AMOUNT
This control sets how loud the bass boost will be. Set it to taste using a wide variety of program material. MORE IS NOT ALWAYS BETTER. Setting this control to MAX will stress the amplifier and the speakers and may cause damage.

POLK/MOMO PRE-EQ SWITCH
A one-button preset bass boost for use with Polk/MOMO Subwoofers. This button overrides the variable bass boost function (bass controls).

INPUT TYPE SELECTOR
Select the type of connections made: LOW "line" level RCA connections, or HIGH level speaker wire connec- tions. Default position is LOW, as the most popular head unit output connections are RCA. To use HIGH level speaker wire inputs, simply attach an RCA connector to your speaker wire, and move this switch to HIGH.

GAIN ADJUSTMENT
Begin with gain set at about the 11o’clock position. Once all settings are made, turn this setting up until your source JUST BEGINS to distort, then back off slightly to cut distortion and operate at optimum gain.

Features:

• Remote Subwoofer Level Control.
• Two sets of standard speaker connections pre-wired for parallel connections, makes hookup simple and delivers pure signal to each paralleled driver.
• Stereo inputs (summed to mono) to insure that you get all the bass whether it’s in the left or right channel. Never miss a beat!
• Variable Bass Boost allows you to choose the amount (0–18dB boost) and frequency (30Hz–160Hz) of the boost to tune your sub/amp system to sound its best in your car.
• Variable Low Pass Butterworth Filter (Bass Crossover): choose the frequency of the crossover from 30Hz–200Hz, and the crossover slope (switchable between 12dB/octave and 24dB/octave) for even more control.
• Exclusive Polk/MOMO Pre-EQ Switch : A one-button preset bass boost for use with Polk/MOMO MM Series Custom Enclosed Subwoofers.
• None of the radio reception interference commonly found in most class D amplifiers.
