1. Y D STREET MACHINE 4 AUTOTEK 2Channel High Performance Mobile Amplifier Model 100X1 Owner s Manual Dear customer Selecting fine audio equipment such as the unit you have just purchased is only the beginning of your musical enjoyment Now is the time to consider how to maximize the fun and excitement your equipment has to offer AUTOTEK and the Electronic Industry Associations Consumer Electronic Group want you to get the most out of your equipment by playing it at a safe level a level that lets the sound come through loud and clear without annoying blaring distortion most importantly without affecting your sensitive hearing Sound can be deceiving Over time your hearing comfort level adapts to higher volumes of sound what may have sounded normal can actually be too loud and harmful to your hearing Guard against this by setting your equipment at a safe level BEFORE your hearing adapts To establish a safe level e Start you volume control at a low setting e Slowly increase the sound until you can hear it comfortably and clearly and without distortion e Once you have established a comfortable sound level make a not of this position and do not go above this setting Taking a minute to do this will help to prevent hearing damage in the future After all we want you listening for a lifetime Introduction Your Autotek STREET MACHINE amplifier has been designed to give you very2. Do not use less than 4 ohm in the mono mode When operating 4 speaker system the impedance of the speaker is an important factor Do not use speakers in parallel for less than a 2 ohm load per channel in the stereo mode Caution Be careful not to connect speaker to the ground or chassis FEATURES AND CONTROLS BETONTE Model 1608 100Wans e Fig Features and Controls RCA Low Level Input Jacks It allows 1 2CH inputs to be connected to the amplifier us9ing RCA plugs Input Level Control It allows for the adjustment of the gain of both channel so as to match the output level of the source X over switch a Low position Allows for the control of the low pass frequency 80Hz b Flat position Allows for full range pass through c High position Allows for the control of the high pass frequency 80Hz Hi Level input connector Connect the radio s speaker output to the high level inputs connector Do not use both lo9w and high level input at the same time Be sure not to confuse high level input with speaker outputs Incorrect connections may damage the amplifier or your source High level input is based on common ground signal High Input Connector White L CH Gray R CH Black Chassis Ground Power indicator It indicates amplifier has turn on signal Fuse It protects both the amplifier and the automobile electrical system from fault conditions Use a standard automotive fuse 100Xi 15A Power connecti
