For example, this feature would allow you to run a pair of mid and tweeters in stereo and a sub-woofer mono (See Page 13). Built-in Crossover The “ELA”amplifiers include a built-in variable **high and low pass crossovers. The crossover features a variable frequency selection (50Hz ~ 250Hz) for precise high or low pass filtering. **Except ELA1190, 1300, 1500 & 1800 which have a 50 ~ 250Hz low pass filter. Bass Boost For added low frequency performance the amplifiers are equipped with switchable 6 or 12dB bass boost @ 45Hz. Line Out One set of full range line outputs have been provided for convenient connection to additional amplifiers in the system. (All models except ELA465 & ELA2150) ENGLISH 4 ELA AMPLIFIERS ENGLISH ENGLISH Subsonic Filter (ELA1190, ELA1300, ELA1500 & ELA1800) A subsonic filter has been provided to filter out unwanted subsonic bass frequencies below the audible range of the subwoofer. This feature helps to improve the amplifier's overall performance since power is not wasted reproducing frequencies beyond the speakers' normal operating range. This feature works in conjunction with the Low-pass crossover to provide band-pass filtering. Phase Adjustment (ELA1190, ELA1300, ELA1500 & ELA1800) The phase switch allows for 0 or 180 degree phase adjustment for the woofers. In most systems, this phase adjustment should be set at 0 degrees. The 180-degree setting is only needed if the subwoofers are out of phase with the satellite speakers in the vehicle. Power Fusing This protects the amplifier against short circuits and excessive current. Remote Turn-on Automatically turns amplifier on when connected to the head unit's remote output. The amplifier will turn on and off with the head unit to save current consumption. This control also operates the reset circuit for the amplifier's protection. It must be connected with the head unit in order to reset protection circuits. Adjustable Input Sensitivity Allows you to fine-tune the level matching between your source and the power amplifier. 5 6 MOUNTING LOCATION Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat. Select the location in which you wish to mount the amplifier. Use caution when mounting amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank in the automobile. Make sure you know where they are when mounting the amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are ready, use a pencil to mark the mounting holes in the bottom panel. After you have marked the locations of the holes move amplifier out of the way and drill small starter holes to make the tapping screws easier to install. Use provided screws to tighten down the amplifier.

At times, the amplifier will need to draw large levels of current that cannot be provided by any circuit in the car's fuse box. We recommended using an 4 to 8 gauge power wire for your connections depending on the amplifier and length of the wire. Strip one end o...
