+LZPNU -LH[\YLZ Gain Control The input gain control is preset to match the output of most source units. Power LED Power LED illuminates blue when the unit is turned on. RCA Input/Pass-Thru Jacks The industry standard RCA jacks provide an easy connection for signal level input. They are nickel-plated to resist the signal degradation caused by corrosion.
+LZPNU -LH[\YLZ Crossover Switch Selectable switch for 80Hz High-Pass (HP),All Pass (AP), or Low-Pass (LP) operation. Variable Crossover Is a built-in 12dB/octave Butterworth filter with a crossover point variable from 50Hz to 250Hz. Protect LED Protect LED illuminates red if a short circuit or to low of an impedance is detected at the speaker connections. The amplifier will automatically shut down if this occurs. Punch Bass This is an adjustable Bass level control centered at 45Hz @ 12dB/octave.

0UZ[HSSH[PVU Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury. Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The power wires carry substantial current and could induce noise into the audio system. 7. Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the amplifier on cardboard or plastic panels.

6WLYH[PVU Adjusting Gain Punch Bass 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). 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. illus.-4.1 3. Slowly increase amplifier gain control until adequate volume is achieved.
;YV\ISLZOVV[PUN Troubleshooting NOTE: If you are having problems after installation follow the Troubleshooting procedures below. Step 1. Check Amplifier for proper connections. Verify that POWER light is on. If POWER light is on skip to Step 3, if not continue. 1. Check in-line fuse on battery positive cable. Replace if necessary. 2. Check fuse(s) on amplifier. Replace if necessary. 3. Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if necessary. 4.
-YHUsHPZ Particularités Techniques (illus.-1.1) DEL d’alimentation / DEL de protection Cette DEL bleue s’illumine lorsque l’appareil est allumé. Cette DEL jaune s’illumine si un courtcircuit ou une impédance trop basse est détecté au niveau des connexions de haut-parleur. L’ampli s’éteint automatiquement si cela se produit.
-YHUsPHZ 5. Préparez le fil de masse NOIR à connecter à l’amplificateur en dénudant son extrémité sur 1 cm (3/8 po). Sertissez le fil dénudé dans un connecteur en fourche ou en anneau et branchez-le sur la borne de masse (GND). Serrez la vis pour fixer le fil. Préparez la masse du châssis en grattant toute trace de peinture de la surface métallique et en nettoyant soigneusement pour éliminer tout dépôt de saleté et de graisse. Dénudez l’autre extrémité du fil et fixez un connecteur en anneau.
,ZWH|VS Características Del Diseño (illus.-1.1) LED de alimentación / LED de protección Este LED azul se ilumina cuando se enciende la unidad. Este LED amarillo se ilumina si se detecta un corto circuito o una impedancia demasiado baja en las conexiones del altavoz. El amplificador se apagará automáticamente si esto sucede. Enchufes RCA de entrada Los enchufes RCA normativos en la industria brindan una conexión fácil para entrada de nivel de la señal.
