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.

450 watts @ 8 ohms (minimum load = 2.6 ohms) Frequency Response (power amplifier): 10Hz to 40kHz Size: 19"W x 5.38"H x 10.5"D (482.6 x 136.6 x 266.7 mm) (3 rack spaces) Weight: 33 lbs. (14.97 kg) 2 • BASS 750 USER GUIDE...
1 volt RMS. Basses with really “hot” pickups may find the Active input more compatible. If you’re using a KEYBOARD or BASS PEDAL, etc. with the Bass 750, we have found the best choice to be the Active input.

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 result- ing 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.
MASTER VOLUME The Master Volume adjusts the level being sent to the power amplifier section of the Bass 750 and controls the overall volume of the unit. It DOES NOT affect the level of the record XLR output in the “line” position.

All patch cords used with the Effects Loop should be as short as possible and should be routed as directly as possible. Running patch cables over the top of the Bass 750 (as with any amplifier) can induce hum in the cables.
Page 9
If a persistent hum exists after trying both positions of the ground lift, there is probably a mis-wire or bad ground in the feed lines to the board or console or a dirty or miswired A/C socket. SWR recommends the pur- chase of an AC wall socket tester which can identify proper wiring (available at most hardware stores).
The Bass 750 is completely ready to be rack mounted and needs no additional parts or accessories other than the case itself. The Bass 750 takes up three full rack spaces (it is 5-3/8" high). If the rack that you mount the Bass 750 in requires that the rubber feet on the bottom of the chassis be removed, please remember to REPLACE the screws, as they help to reinforce the chassis.

This prevents the Bass 750 from flexing downward if the rack case is dropped. If you must mount the Bass 750 in an area of the rack other than the bottom space, a piece of wood or similar solid material should be installed between the bottom of the rack case and the bottom of the amplifier to prevent flexing of the amplifier’s chassis.
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.
