MOUSE MAXI MOUSE PORTABLE AMPLIFIERS OPERATING INSTRUCTIONS and trouble-shooting guide LECTROSONICS, INC.
INTRODUCTION Mouse was introduced to the Music Industry in 1979. It was the first rechargeable, portable amp with enough power to satisfy the demands of the professional. It puts out more sound than anything near its size. Since that time, the Mouse has continued to be the Number One choice of street musicians throughout the world, and will be found sitting around the studios of some of the finest guitarists in the world. The Maxi Mouse model was introduced in 1984 as a "step up" unit.
GENERAL DESCRIPTION The Mouse was designed for the guitarist. The system is equalized with a preset frequency response determined by analyzing a number of guitarist’s preferences using graphic equalizers. The tone control offers a very wide adjustment range. The result is a guitar amp with large amplifier "bite" and a response that musicians prefer. It works with virtually any effects box available. The Maxi Mouse is a rechargeable battery operated, dual input amplifier.
CONTROLS AND FUNCTIONS - MOUSE PORTABLE SPEAKER/AMP INPUT JACK This is a switching jack that turns on the amplifier when you plug in your instrument cord. The red LED above it indicates when the amp is on. The input is compatible with Hi or Lo impedance pickups (magnetic or contact) without the use of a preamp. VOLUME CONTROL This is a feedback-type volume control and is more sensitive than the controls found on most other amplifiers.

CONTROLS AND FUNCTIONS MAXI MOUSE PORTABLE SPEAKER/AMP INPUTS AND VOLUME CONTROL INPUTS "A" and "B" are standard 1/4" phone jacks which may be used with either an instrument or a high impedance microphone. These are switching jacks that turn on the amplifier when you plug in your instrument cord. The input impedance is 10 megohms to match any type of instrument pickup. When used with low impedance microphones, a matching transformer should be used to convert the microphone output to high impedance.

TROUBLESHOOTING GUIDE BEFORE GOING THROUGH THE FOLLOWING CHART, BE SURE THE BATTERY PACK IS FULLY CHARGED. The POWER LAMP should light up when the unit comes on. The POWER LAMP will grow dim as the batteries discharge. Keep the batteries fully charged when not in use to insure long battery life. Continuous charging will not harm the battery pack, although it is not necessary. In extreme cases a continuous charge of ten days may be necessary to restore a deeply discharged battery pack.
TROUBLESHOOTING GUIDE (cont.) SYMPTOM POSSIBLE CAUSE DISTORTED SOUND FROM SPEAKER 1) Volume set too high. Reduce volume control. 2) Excessive wind noise or breath "pops". 3) Batteries very low. Recharge batteries. As the batteries discharge you have to turn up the volume. When the volume knob is turned all the way up and you’re still not getting much volume out of the system, the amplifier is being driven to its limit and usually produces distorted sound. EXCESSIVE FEEDBACK 1) Volume too high.
