0dB INPUT: Connect your “passive” bass guitar here using a shielded instrument cable. This input is not padded and is best suited for basses without active electronics or “hot” pickups. 2. -15dB INPUT: Connect your “active” bass here using a shielded instrument cable. This input is padded 15dB and is best suited for basses with active electronics and/or “hot” pickups. 3. VOLUME: Use this control in conjunction with your instrument’s volume controls to adjust the output level of the amplifier. Th

• Always keep the total speaker impedance at or above the rated load. • Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the amplifier. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film. • Do not use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the unit to an authorized service center for inspection. • Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing loss

by V-50H Guitar Amplifier Thank you for choosing Ampeg. In order to obtain the best performance from your new amplifier we recommend you review the information in this owner’s guide prior to its use. 12 3 THE FRONT PANEL: 1. Power switch is used to turn the amplifier on and off. 2. Power light indicates the amplifier is turned on by glowing an iridescent blue color. 3. Reverb controls the amount of reverberation applied to the signal. With the control at the “0” position there is no reverb appli

El diodo LED de Picos (#3) se iluminara en forma constante cuando el amplificadora se utilice de esta manera. 6. BAJOS: Esta perilla sirve como el control primordial para las frecuencias bajas. Esto permite un rango de 8dB de recorte o de refuerzo a 50Hz. B3/B328/B3158 Bass Amplifier The Front Panel Controls and Their Use 7. ULTRA-MEDIANOS: Este es el control primordial para el rango de las frecuencias medianas. Gire el control del centro hacia la izquierda para lograr un sonido de contorno (mas

Conecte esta Terminal para conservar limpia la senal. Esto atenuara la senal de entrada hacia el preamplificador, lo que le permitira obtener la mejor relacion de senal-a-ruido para su bajo. 3. DIODO (LED) DE PICOS: Este LED se iluminara cuando cualquier etapa de preamplificacion se encuentre cerca del punto de sobreimpulso. Ajuste el control de Ganancia (#4) hasta que una senal fuerte de su bajo cause un parpadeo de este LED. NOTA: Si el LED permanece iluminado aun con la Ganancia en una posici

12. EQUILIBRIO (SOLO EN EL B358): Este control varia el nivel de la senal entre las salidas de bajas y altas frecuencias (vease el #18) para adecuar aun mas el sonido). 13. DIODOS LED DE LIMITE: Este LED indicador parpadeara cada vez que se requiera el circuito limitador interno para conservar limpia la senal de salida del amplificador. Esto indica que el amplificador esta aproximandose a su salida maxima y que el limitador esta impidiendo el aplanamiento (“clip ping”) de la senal de salida. NOT

For full range, wire the Speakon® connectors as follows: Pin 1+ : Full Range positive (+) Pin 1– : Full Range negative (–) BI-AMP OPERATION: • Set the Mode switch to the “Biamp" position. • Set the crossover point for the amplifiers somewhere in the 100Hz to 300Hz range. Once up and running, adjustments within this range may be made to suit your personal listening palate. • 1/4” JACKS: Connect the output of your low frequency amplifier to either of the two 1/4” jacks labeled “Full Range Inputs (

Outstanding sound and legendary Ampeg performance have been embodied in rugged, stylish cabinets which are incredibly road-worthy and surprisingly manageable. The PR-1832HE is a four-way full range bass speaker system inspired by Victor Wooten. This enclosure packs the punch of traditional 2-10 / 4-10 cabinets, but with the added advantage of the built-in 18" subwoofer. This enclosure is designed for high SPL and low distortion. The frequency response is smooth and accurate all the way down to 3
