1. Full Range Full Range Subwoofer Full Range BY Full Range 3 Channel Combo 2ch HP 1ch Subwoofer Like the four channel systems as shown above the benefits and performance trade offs are similar But this system configuration offers an additional advantage with the internal high pass crossover This crossover reduces the bass to the front speakers thus protecting them under heavy low frequency loads A typical system with larger drivers in the back is then able to be pushed harder without worry over the power handling on the front speakers SYSTEM CONFIGURATION 4 OR Subwoofer LP 4 This installation is most popular for listeners who want to simply increase the power to the rear speakers in a car The resulting performance is most commonly a louder overall sound field from the rear o Full OR Sey Full Range HP 2 Channel Full Range HP LP But such a system s biggest benefit is the additional bass response since the bass control of the radio can be turned up without distorting the amplifier Such a system is not necessarily louder in the mids and highs but is able to play louder in the low frequencies due to this additional power This leads to an overall richer and stronger sound experience for the listener without additional subwoofer boxes or electronics that may complicate the system or take up more room Such a system WILL NOT equal the performance of a subwoofer system bu2. 12 Battery Trigger POWER CONNECTIONS amp TRIGGER LINE SPEAKER OUTPUTS The amplifier is connected to appropriate impedance speakers via these leads It is IMPERATIVE that these leads NOT be connected or touch the vehicle chassis in any way or the amplifier will be damaged The and leads of the amp are in no way inter connected to one another Also NONE of the leads can touch each other touch ground or touch 12V or damage may occur to the amp or vehicle GROUND This is the high current ground connection to the chassis of the car It should be fastened to a clean ground connection in the vehicle capable of handling high current loads This wire should be no longer than 3 feet 1 meter 12v A high current line run direct from the batter is highly recommended to insure adequate current and voltage This line MUST be run through a dedicated fuse of some kind and this fuse should be located immediately next to the power source This in line fuse is used to protect the vehicle should a short to chassis occur TRIGGER This line tells the amp to turn on and is remotely switched from the radio which normally provides an amp trigger output This line is required to go high 12V to turn on the amp If this line is not available use the power antenna line trigger which is normally available in most radios FUSE These fuses are only for catastrophic situations should the amplifier begin to self destruct o

4. Protection Frequency LED LINE LEVEL INPUTS amp OUTPUTS The most commonly used inputs amp outputs in the aftermarket are RCA type line level inputs These can handle up to about 6 Volts rms without overdriving the amplifier Such high voltages are rarely found from car audio head units so this is a very comfortable value But should the use need to drive the amp directly from speaker level leads use the supplied High Level Adapter to connect to the amp GAIN CONTROL The gain control allows for a range of 0 3 6Volts input This means that if the setting is a 0 3V it only takes 0 3Volts to drive the amp to full output Such a low setting allows for the amp to be easily overdriven and more susceptible to noise so a mid position is highly recommended for most radios CROSSOVER MODE SELECTOR Depending upon the system design chosen you need to set the amplifier in the proper mode be it LP Flat or HP The low pass and high pass frequency settings are explained below The Flat setting simply allows for the amp to pass all audio frequencies without any kind of crossover filter application This is common with 6x9 fullrange coaxial speakers for example HIGH PASS CROSSOVER CONTROL If the control is in the HP position the amplifier passes only mid and high frequency sound The lower limit for such sound is set via this control A common setting is just above 100Hz LOW PASS CROSSOVER CONTROL If the control is
5. in the LP position the amplifier passes only low frequency sound The upper limit for such sound is set via this control For bass a value just below 100Hz is usually best BASS BOOST This control provides additional bass in the 45Hz area to give a stronger low end feel to the bass Once switched on this will also allow the amp to be driven into distortion sooner so the user must be aware PROTECTION LED This light turns on if the amplifier senses a severe problem such as a speaker short circuit POWER ON LED This light will turn on when the amplifier receives a 12V turn on signal from the radio If the amp is properly wired but the light does not turn on there may be a short circuit condition that the amp is protecting itself from gt 27 www midwestelectronics com SYSTEM CONFIGURATION 1 go PEA EEEMALAE O gt oe oT CHE 1 E 1 gt Y _ s _e g 5 ATO See Full Range HO ran Subwoofer 5 Channel Combo 2ch HP 3ch passive Multi Mode The multi mode system is a poor man s satellite subwoofer system This amplifier is able to drive speakers in stereo mode and at the same time drive low frequencies to a dedicated subwoofer speaker By inserting inductors coils and capacitors the result is an inexpensive solution to generating a 5 channel system with a 4 channel amplifier Using passi
