BASS 750 USER GUIDE INTRODUCTION CONGRATULATIONS... ...you are now the proud owner of a SWR Bass 750 amplifier! The Bass 750 was designed in response to a demand for an amplifier that delivered the volume and punch of classic high-powered amplifiers, coupled with the sound and clarity that SWR is known for. At 750 watts (mono), the Bass 750 is extremely loud, and its simple front panel controls make it a breeze to dial-in the perfect bass tone.

FRONT PANEL FEATURES INPUT JACKS Both input jacks accept a standard 1/4" phone plug and both inputs can be used at the same time. Since the two inputs are totally independent, no loss in volume or tone will occur if two instruments are used simultaneously. Please keep in mind, however, that the Active/Passive input has five times more gain than the Active input. PASSIVE/ACTIVE INPUT A “passive” instrument has no built in preamp and does not use a battery.
AURAL ENHANCER SWR’s Aural Enhancer control was developed to bring out the fundamental low notes of the bass guitar, reduce certain frequencies that help mask the fundamentals, and enhance the high end transients. The resulting frequency response is similar to that used for recording the bass in the studio. This effect becomes more radical as the control is turned to maximum. The result is a more “transparent” sound and is especially noticeable when slapping/thumb-style on the bass guitar.
EFFECTS BLEND This control blends the signal sent from your bass with that coming from your effects unit. With the Effects Blend control fully counter-clockwise, no signal from your effects will be heard (“dry”). As you turn this control clockwise, more of the effect can be heard in the overall sound. When the Blend control is fully clockwise (“wet”), no true or unaffected signal is heard other than what your effects unit provides.
Proper size of the AC fuse for all countries is 3AG. Proper rating of the fuse is as follows: Japan: 8 amp slo-blo United States: 8 amp slo-blo Europe (240V): 4 amp slo-blo AC CORD RECEPTACLE Accepts a standard AC power cable (supplied with the Bass 750), used with almost all current musical, professional and household electronic devices. If you misplace your AC power cable, a replacement can be found at almost any computer. electronics, or pro audio store.
The fuse can open as a result of a fault in the speaker cable, the speakers themselves, or the power amp being sent well into clipping. With this in mind, we recommend keeping spare fuses with the amplifier at all times. SPEAKER JACKS Two 1/4" phone jacks (wired in parallel) and two Speakon® connectors (wired in parallel) are provided for hooking up your speaker system. The minimum load (or impedance) the Bass 750 is designed to drive is 2.
Wiring for the XLR connector is as follows: Pin 1 = ground, Pin 2 = +, Pin 3 = – (negative) (American Standard) The Bass 750 is compatible with Phantom Power-equipped mixing consoles. TUNER SEND The Tuner Send allows the user to plug an instrument tuner into this jack and tune up without having to unplug and go back and forth from amp to tuner. This feature is totally isolated from the rest of the preamp and will function regardless of the settings on the front panel.
The Bass 750 should be mounted as close to the bottom of the rack case as possible. The height of the rubber feet was chosen so that when you slide the unit in the bottom of the rack case, the rack mounting holes on the front panel will line up with the mounting holes of the rack rail. This prevents the Bass 750 from flexing downward if the rack case is dropped.
LIMITED WARRANTY The BASS 750 from FMIC is warranted to the original consumer purchaser for TWO YEARS from the date of purchase, against defects in materials and workmanship and provided that it is purchased from an Authorized SWR Dealer. This warranty applies only to products purchased in the USA or Canada.
