Finally, connect the main +12 volt cable to the battery, with the main fuse removed, and we are almost ready to power up the system. Power up the system: The following procedure may seem like overkill, but there is nothing more frustrating when turning on a system for the first time, and it does not work properly immediately. First, make sure the head unit is off, and turn all level controls to minimum (counterclockwise), including the head unit volume control. Set all equalizers to 0 dB (no boost), and all crossover frequency controls at approximate frequencies, as recommended by the loudspeaker manufacturer. Set all input selector and crossover switches as required for the application. Remove all amplifier fuses, and insert the main fuse at the battery. If the fuse does not blow, you can insert the fuse in one of the amplifiers, and we are ready to turn on the system. Turn the head unit on, insert a CD, or select a radio station, and increase the head unit volume control. If the system sounds fine, turn off the head unit, and install fuses in the remaining amplifiers, one by one, till the complete system is powered up and functioning properly. It is highly recommended that the amplifier be mounted to a board of MDF or other solid structure using the 4 mounting screws provided. Avoid mounting the amplifier to metal as this can introduce noise and other unwanted issues. When mounting the amplifier, ensure that it is mounted HORIZONTALLY, as shown in the diagram above, for optimal heat dissipation. Mounting amplifiers to speaker enclosures is not recommended as this can cause damage to the amplifier components. When choosing a location for mounting the amplifier, ensure that you check for clearance from wires, gas tank, electrical devices and brake lines etc. NOTE: This Matrix is a general rule of thumb. Please refer to the manufacturers specific requirements. Samson specifications can be found on page 6. WOOD SYSTEM 7-10 ft. 10-13 ft. 13-16 ft. 16-19 ft. 19-22 ft. 22-28 ft.

The mono amps are capable of 4, 2 - Crossover filters are 12dB/Octave. and 1-Ohm. - A POWER LED indicates the powered up and turned on condition. - All Hifonics amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit, and amplifier DC faults indicated by the red “PROTECT” LED. 2 -The LINE INPUT signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying daisy chaining of amplifiers. -SUBSONIC: Allows you to adjust the crossover filter from 15Hz to 55Hz. -LOW PASS: Allows you to adjust the LOW PASS crossover filter from 40Hz to 150Hz. LEVEL: Adjusts the input sensitivity from 0.2 volts to 6 volts. BASS BOOST: The BASS BOOST is adjustable from 0db to 12dB. REMOTE: This is the input jack for the remote Level control. LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 6V. LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal. The mono amps are capable of 4, 2 & 1-Ohm loads. Operating the amp below 1-Ohm can cause damage to the amp not covered in the warranty. HS1500.1D / HS2500.1D MONO BLOCK AMPLIFIERS The 4 channel amps have the same features as the 2 channel models accept that there are 2 sets of controls. 1 set for channels 1 & 2 and 1 set for channels 3 & 4. In addition, the 4 channel models have a Mode switch which allows you to select 2, 3 or 4 channel operation. Switch to 2 channel if you only have 1 set of RCA’s in CH 1/2 and the unit will automatically supply signal to channels 3/4. Select 3 channel when you only have RCA’s in CH 1/2 but plan to run channels 3/4 bridged. Select 4 channel if you are providing RCA’s to channels 1/2 and 3/4. The X-OVER slide switch selects the internal crossover functions: -The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying daisy chaining of amplifiers. -HPF: Selects the built in HIGH PASS filter, variable from 60 Hz to 1.2kHz. -FULL: Bypasses all crossovers for full frequency range operation. -LPF: Selects the built in LOW PASS , variable from 30 Hz to 250Hz. MODE: The mode switch allows you to choose Ster...
