INTRODUCTION INTRODUCTION Congratulations on your purchase of the SWR Power 750! You now own one of the meanest, toughest and loudest power amps ever made specifically for bass guita r. Bassists have a unique burden when it comes to powe r, because it takes considerably more power to amplify lower frequencies than it does for higher ones.

POWER 750 SPECIFICATIONS POWER 750 SPECIFICATIONS The Power 750 Power Amplifier from SWR Sound Corporation is a high qualit y , all purpose power amplifie r . It uses a discreet power suppl y , quasi-complementary power amp design utilizing SIX 15 amp, 250 volt bi-polar NPN devices direct coupled to the output via an in-line speaker fuse.
GETTING STARTED GETTING STARTED CONNECTING YOUR SPEAKER CABINETS CONNECTING YOUR SPEAKER CABINETS The Power 750 is a MONO amplifier. All of the speaker outputs (both 1/4" and Speakon) are in parallel, meaning that they all run off of the same mono power amplifier inside the unit.
TURNING THE UNIT ON TURNING THE UNIT ON Remove the AC cable from the accessory pack and connect it from the amplifier's AC receptacle to a standard wall outlet. Make sure that the Volume control is set to the minimum position. Locate the power switch on the right side of the front panel and turn the amplifier on.
FRONT PANEL FEATURES FRONT PANEL FEATURES RACK HANDLES RACK HANDLES The rack handles were chosen for comfort while carrying your Power 750 from place to place. They will also protect the front panel controls in the event the unit is dropped on its face.
REAR PANEL FEATURES REAR PANEL FEATURES INPUT SECTION INPUT SECTION UNBALANCED INPUTS UNBALANCED INPUTS This is the main power amp input jack for most applications, and should connect to the "Unbalanced Output" on your preamp of choice (preferably an SWR Interstellar Overdrive or Grand Prix!).
HOW IMPEDANCE AFFECTS POWER RATINGS HOW IMPEDANCE AFFECTS POWER RATINGS People often have questions about impedance. What is it? The root of the word "impedance" is the verb "impede", which means to block or resist. That's what impedance is - resistance to power.

SPEAKON VS. 1/4" JACKS SPEAKON VS. 1/4" JACKS We have found the Speakon connection to be superior in both stability and amperage conductivity, and so we have provided Speakon output jacks in addition to the standard 1/4" jack.
A FEW WORDS CONCERNING HEAT A FEW WORDS CONCERNING HEAT One of the most asked questions about our amplifiers is why they tend to get warmer than other amps. The chassis of your amplifier can get quite warm during normal usage. This is especially true if you are are driving the amplifier at its minimum impedance.
ELECTRICAL AND GROUNDING CONSIDERATIONS ELECTRICAL AND GROUNDING CONSIDERATIONS In a rack system with a large power amplifier such as the Power 750, placement of effects units and preamplifiers with respect to the power amplifier may be important as hum induction may occur.
LIMITED WARRANTY LIMITED WARRANTY The POWER 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.
