Congratulations on your purchase of a new Lanzar Opti signal processor. Opti mobile electronics are some of the most advanced car audio products available. These quality audio products are designed and engineered to afford you years of uncompromising musical service. Lanzar has utilized the latest electronic technologies in order to deliver a superb listening experience. The E-15 Equalizer offers the listener the ability to intensify the listening experience, add realism to their mobile system, overcome his or her vehicle’s unique acoustic properties, and tailoring the sound to their preference. The E-15 was designed with the goal of achieving the finest music reproduction. Although the way it sounds to you is the ultimate decision maker in how you set up your car audio system, we suggest the use of a sound analyzer to give you exact audio measurements of your car’s interior so that you can achieve precise equalizer settings. Of course, the E-15 can and should also be adjusted to your preference. Finally, a tip – once you achieve the optimum settings for your system, don’t keep changing them to suit particular program material! Also, we suggest you write the settings down and keep this record in case they ever accidently get changed. This could save hours in having to experiment all over again. table of contents general features 2 precautions 3 features and specifications 4-5 system wiring 6-9 mounting and installation 10-11 noise check and system adjustment 12 troubleshooting 13 general features 15 Band Equalizer Controls per Channel in 1/2 and Full Octave Steps Blue Light Illumination ± 12 dB Boost/Cut at Each Frequency Setting Front, Rear and Line Outputs Separate Front, Rear and Line Output Level Controls Front/Rear Fader Control Power LED Indicator EQ Bypass Switch Gold-Plated Connectors and Terminals 2 Precautions To prevent short circuits, be sure to disconnect the negative battery ground lead before wiring the system up. When you finish the installation, be sure to make one more check to be sure everything is done correctly. Reinstate all car parts that were removed.

This fader takes priority over the fader in your car stereo head unit. The 15 band equalizer controls divide the frequency control range into 1/2 octave steps at 20Hz, 30Hz, 45Hz, 67Hz, 100Hz, 150Hz, 200Hz, 350Hz, 500Hz,800Hz,and at full octave steps, 1100Hz, 2200Hz, 4400Hz, 8800Hz, 17200Hz. Each rotary control permits the signal at that control’s frequency to be either increased (by turning clockwise) or decreased (by turning counter-clockwise) by up to 12 dB. When set to the center detent position, the control provides no increase or decrease at that frequency. There are separate level controls on the E-15 for both the left and right channel outputs. When installing and first setting up the system, set the output level controls to the center detent position for a starting point. Typically, when the head unit volume is set to approximately the 2 o’clock position your system is at its ideal volume. Set the head unit volume this way, and then adjust the outputs on the E-15 accordingly to achieve the ideal volume without over-driving the inputs of your amplifier, which will create distortion. The goal in the adjustment is to obtain the best signal-to-noise ratio while obtaining your desired listening volume. This switch controls whether or not the E-15 is providing equalization (”IN”) or simply passing signals through in an unaffected way. The line inputs are connected to your head units RCA outputs. If your head unit has a fader that fades between two sets of RCA outputs make sure that the head unit fader is turned toward the set of RCA connectors that you are using. If your radio has only speaker level outputs you can connect the E-15 to your head unit via a high/low level adapter (for example, a Pyramid NS-60 or equivalent). This separate component allows you to connect your speaker wires from your head unit and the RCA cables from the E-15 while balancing the head unit’s output and the equalizer’s input. Connect these outputs to the appropriate inputs of your power amplifier(s). The front outputs connect to the amplifier driving your front speakers, the rear outputs for the rear amplifier. Connect this output to another signal processor type device in your system, such as a crossover. Th1s line output level is unaffected by the fader control. This indicator lights up when the internal power supply is activated and the unit is operational.
