The extended use of a high powered audio system may result in hearing loss or damage. While TUBE DRIVER systems are capable of "Concer t Le v el" volumes with incredible accuracy , they are also designed for you to enjoy at more reasonable levels all of the sonic subtleties created by musicians.
1 Power Bandwidth: 5 Hz -50 KHz T otal Harmonic Distortion: 0.2% or less (A-weighted) Input T opology: Balanced Differential Input Sensitivity: 500mV - 12 volts RMS Input Impedance: 10K Ohms Output Im.
Recommended Fuse Rating f o r M A 4100 i s 1 0 0 Amps Y ou will need to install an in-line fuse or circuit breaker in the po wer wire within 18” of the battery . This fuse or cir cuit breaker protects y our vehic le from fire in case the po wer wire shor ts to the vehic le body .

7 Input Jac ks The MA4100 includes both RCA and Mini-Din (balanced) inputs. The supplied RCA connections allow you to use the MA4100 with other brands of audio gear . Our Diff erential RCA inputs provide a dramatic impro v ement in noise reduction ov er standard RCA input types.
8 Input Gain Contr ols There are two Input Gain Controls located on the end panel under the RCA input jacks. These are not v olume controls! These controls match the output signal voltage of the source unit to the amplifier inputs.

Do you have 12V at the amplifier ’s connections? 11 No Sound Is the W ARM UP LED illuminated? YES NO YES The warm up cycle can take up to 40 sec., Is there sound after that? NO Y ou’re done Is there signal on the RCA ’s? YES NO Does the amp remote (REM) have 12V? Check all connections.
12 No Sound in One Channel YES Reverse the left and right inputs. Check the pre-amp (RCA/Mini-Din) cables for open connections and make corrections. Did you find open connections? NO Y ou’re done SOUND IS NO W IN... Opposite Channel Problem is in the speaker or speaker wire of the silent channel.
Noises While the Engine is On Alternator whine: This noise changes in frequency with engine RPM. Check for: . Excessive input le vel setting on the amplifier . High resistance in cab ling or corroded and/or loose connections . P olarity of the input cab les If the problem persists, check the whines and pops chec klist below .
Check each side of the amplifier independently to see if the distortion is only on one channel. Is that the case? 14 Noises While the Engine is On or Off System hiss: Distortion: Distortion is garbled sounding music. This can often be caused by a shorted speaker wire.
