User manual BLITZ BZX7

[. . . ] By turning the selector you can choose the high-pass crossover points from 40Hz-8kHz. Positioning this switch is at high pass mode, the low pass filter cannot be used. Positioning this switch at the"10" changes crossover points from 40Hz-800Hz to 400Hz-8kHz for high frequency high channel drivers. See page 6 (signal connection diagram) Allows you to change the phase of your subwoofer 0 or 180 degrees to help compensate for timing differences between drivers.

Mark the location for the mounting screw holes by positioning the crossover where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. Before attempting to drill the mounting holes, take note of any wires, lines or other devices in your vehicle which may be located behind the mounting surface!Then drill pilot in the mounting surface for the mounting screws and insert then. Tighten the screws securely. BTS-1 4ø x12N x 4 SW 4ø(B) x 4 PW 4ø(B) x 4 7 Noise check and system adjustment NOISE CHECK Check the entire audio system for noise before permanently securing the CROSSOVER mounting 1. Rev the engine and vary the VOLUME of the audio system to determine if there is any unwanted noise. If so, turn both the audio system and the engine off. Do not secure the CROSSOVER mounting screws. Refer to the "Trouble Shooting Guide" at this manual. If the audio system does not have any noise, securely tighten the CROSSOVER mounting screw and double check the wiring cables for safe placement. SYSTEM ADJUSTMENT Preliminary Adjustments Pre-setting the system provides a necessary starting point for fine-tuning the entire audio system to maximum performance. NOTE: DO NOT MOUNT CROSSOVER UNTIL THE FOLLOWING PROCEDURES HAVE BEEN COMPLETED. Preset each amplifier input gain adjustment at the amplifier to half of maximum. Before turning the audio system on, preset-adjust the front, rear and sub-woofer output level controls, as well as the front channel high-pass and subwoofer channel low-pass crossover points. Slowly turn the volume up and listen carefully for: obvious trouble in sound (distortion, no sound, no hiss, total silence). Turn the system off refer to "Trouble Shooting Guide" at this manual. 8 Caution DO NOT ROUTE AUDIO CABLES AND POWER CABLES TOGETHER!THIS CAN CAUSE ENGINE NOISE IN YOUR AUDIO SYSTEM.
