Momentum Momentum Amplifier none User manual

ThankyouforpurchasingthisMomentumAmplifier.
Please read this manual carefully before beginning your installation. Should you need technical assistance during or after your installation,
pleasecallourtechnicalhot-lineat7323705400between10:00AMand5:00PMEST.
WARNING: Use of this amplifier at extreme high volumes for extended periods of time may cause hearing loss and or hearing damage.
During periods of prolonged high volume levels it is recommended that you use ear safety devices. Playing Momentum amplifiers at high
volume levels while driving will impair your ability to hear necessary traffic sounds. While driving always keep your sound volume at
reasonablevolumelevels.

Fully Independent High Performance MosFET Power Supply.
High Capacity BiPolar Output Transistors.
Fully Adjustable Built-in Electronic Crossover System.
Independent/Variable High Pass and Low Pass 12dB Crossover Adjustment.
+12dB Bass Boost Circuit.
High Level OEM Speaker Input Port.
Soft Start Mute & Delay Turn On Circuitry.
2 Ohm Stereo/4 Ohm Mono Capable.
INSTALLATIONDIRECTIONS
The power connections can accept 8 to 10 gauge wire. Be sure to strip just enough wire that fits into the terminal without exposing excess
copper.Thiswillprotectagainstshortsfromexposedwireswhichmaytouch.
Momentum amplifiers feature very sophisticated protection circuits. Should the amplifier reach an unstable operating temperature
greater than 80 degrees C it will shut down. Allow the amp to cool sufficiently before restarting the system. In some instances the Logic
controlofthepowersupply will not shut down the amplifier completelybutwillspurttheamp on and off. Turnoff your system and allow it to

ADJUSTING YOUR SYSTEM.
Wheninstallingthe system,youcan not useboththeRCA inputs andtheHighLevelSpeakerinputsatthe same time.Youmustchooseone
method or the other. Never run your RCA cables on the same side of the vehicle as your power and ground wires. This will help avoid any
electricalnoisefromgettingintoyoursystem.Itisrecommendedthatyouusehighquality,shieldedRCAcables.
To properly set your amplifier level control, turn the amplifier level control to 5 volts (minimum) and your head unit to maximum volume.
Begintoturnthe amplifier gain towards150mVuntilyou to hear the musicbegintodistort.At thatpointturnthe gain back a droptowards5
volts and your system is set. The amplifier gain/level setting is not a volume control-it is a sophisticated circuit meant to match the preamp
voltage of your signal source to the amplifier preamp circuit. Setting the amp gain to maximum when not necessary-will increase the
chanceofnoiseanddistortionenteringyoursystem.

high frequencies to be played and filters out all low frequencies from reaching typically smaller midranges and tweeters which can be
damaged from powerful low frequency signals. HP=HIGH PASS, this means that the amplifier is playing in the full range mode without any
frequenciesbeingfiltered.

Please be sure that your speakers can handle the increased 12dB of output before turning on the circuit. You may want to reduce the
amplifier gain so that you do not bottom out your drivers when testing the Bass Boost circuit.

TROUBLE SHOOTING GUIDE
Beforeyou powerup thesystem forthe firsttime,pleasecheck thatall yourconnections aretight andseated properly.Use a
volt meter to check that all equipment is receiving 12Volts and that all grounds are good. Check to make sure that all
switchesandpushbuttonsareintheirproperposition.

particular speaker-that particular speaker must be shorted or the speaker wire may be shorted, replace the speaker and/or
thewire.
Diagnosing Noise in your system can be tricky, first thing to do is to disconnect the RCA cables, if there is still noise-make sure
your ground connection is to a real ground location of the vehicle. If the noise stops when you disconnect the RCA cables
thatmeansthatthe noiseisoriginatingfroma sourceotherthantheamplifier.Possiblereasons couldincludeagroundloop,
or badly ground head unit, equalizer or electronic crossover. Faulty alternator, old car battery, worn ignition wires, or bad
