1. BACKSIACE SOR OPERATING GUIDE S Your new Backstage is a professional compact amp featuring one 10 heavy duty speaker mounted in an open back cabinet and powered by our 18 Watt RMS 5 THD chassis The full complement of controls includes Gain Low Mid High and Master Gain The inclusion of the Master Gain makes the Backstage the ideal studio or practice amplifier for those who don t want to drag monster amps around for practice or recording sessions The Backstage also features a preamp output jack for driving external power amplifiers or accessories Unlike most units in this category which offer only one or two output devices the rugged power amp of the Backstage uses four extremely heavy duty push pull parallel silicon power devices mounted on large heatsinks coupled with four 5 Watt emitter resistors thus providing the ultimate in reliability and extra drive necessary for the solid punch and reserve power delivered by this unit The push pull parallel circuit has proven its reliability over the years in our solid state products The rugged cabinet is covered in super heavy duty 33 ounce Tolex to stand up under road conditions The heavy duty 10 speaker has been specially matched to the electronics and cabinet to reproduce the dynamic range and wide frequency response of the Backstage We feel that our Backstage is the best compact amp value on today s market Comparison with other brands will show that th2. hazard exists when the amp is operated with the proper grounded receptacle CAUTION TO PREVENT ELECTRICAL SHOCK DO NOT REMOVE CHASSIS FROM CASE NO USER SERVICEABLE PARTS INSIDE REFER SERVICING TO QUALIFIED SERVICE PERSONNEL SERVICEMAN MUST DISCONNECT LINE CORD BEFORE REMOVING CHASSIS SPECS Input Impedance 47 0 K Ohms Input Required for Rated Output 10 0 mV RMS Input 5 Master 5 EQ flat Gain 60 0 dB Signal to noise Ratio 50 0 dB Recommended Load PEAVEY Power Output ELECTRONICS 18 Watts RMS 5 THD Equalization Frequencies Bass 100 Hz Mid 450 Hz Treble 10 kHz Specifications are subject to change without notice 711 A Street Meridian Mississippi 39301 Telephone 601 483 5365 Y Telex 504115 18 Watts RMS 1 THO BRE CORPORATION Printed in US A
3. is is a professional designed and constructed unit selling at a price comparable to other makers toy amps a WARNING To prevent electrical shock or fire hazard do not expose this appliance to rain or moisture A In most cases when plugging in your instrument you should use input jack 1 Input jack 2 is the low gain input and should be used if the signal from your instrument tends to overload distort input 1 When two instruments are plugged into jacks 1 and 2 the circuit automatically balances the gain of the two inputs so that the sensitivity of both are equal B The Gain control sets the gain of the input preamp thereby controlling the sensitivity of the preamp not the power of the amp Itis entirely possible for the amp to be driven to full power output on very low volume settinys if the signal from your instrument is extremely high and Master Gain is set high C The Low Equalizer varies the amount of bass response in the system and is very effective in achieving a balanced tonal blend D The Mid Equalizer enables the musician to tailor the vital mid range responses Experimentation with the unique middle circuit will show that it is much more effective than conventional circuits E The High Equalizer varies the high end response of the amplifier F The Master Gain control is very useful for obtaining a number of effects The most common use of this control is for obtaining overdrive and sustain at low sound levels Ano
4. ther valuable use for this control is for controlling the response and noise of the amp in the recording studio To obtain maximum overdrive and sustain the channel Gain control should be set near maximum and the output of the system should be adjusted with the Master Gain control It has been found that when operating the amp in the overdriven condition lower settings of the treble control tend to give a smoother natural distortion characteristic Boosting of the Mid Equalizer yields a much fatter distortion The normal background noise hiss hum etc can be very effectively controlled for recording studio applications by use of the Master control To reduce these noises reduce the setting of the Master Volume control G The pilot light indicates when the electrical supply mains is supplying power to the amplifier H The fuse is located within the chassis and should be replaced with one of the proper value if it should fail It is necessary that the proper value fuse be used to avoid damage to the equipment and to avoid voiding the warranty If your amplifier blows fuses the unit should be taken to a qualified service center for repair For your safety we have incorporated a three wire line mains cable with grounding lug It is not advisable to remove the ground pin under any circumstances If it is necessary to use the amp with the old two prong sockets a suitable adaptor should be used Much less noise and greatly reduced shock
