LOW PASS: N/A Interconnect cable checklist: Channels 3/4: - Using good quality RCA cables, feed the front and rear outputs of a head unit to - HI PASS: 100 Hz the inputs of the 4 channel amplifier as shown. - LOW PASS: N/A - Also connect the LINE OUT of the 4 channel amplifier to the LINE INPUT of the 2 channel amplifier as shown. 2 channel bass amplifier: - HI PASS (Subsonic filter): 10 Hz to 40 Hz Mono bass woofer wiring: - LOW PASS: 80 Hz Connect the mono speaker positive terminal to the LEFT +, and its negative terminal to RIGHT -. Please note that these frequency points are suggestions only. Refer to the loudspeaker manufacturer specifications and the section “Setting up systems Switch setting checklist: after installation for best performance” 4 channel highs amplifier: - 1/2CH X-OVER: HPF Level control checklist: - 3/4CH X-OVER: HPF - Refer to the section “Setting up systems after installation for best performance” 2 channel bass amplifier: Minimum final loudspeaker impedances: - X-OVER switch: LPF - 2 ohm per channel in stereo mode. - 4 ohm mono bridged.

Subsonic: This setting acts as a low frequency cut off for your system bass reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the Subsonic to 25Hz, the amplifier will not play frequencies below 25Hz but will play frequencies from 25Hz to the chosen Low Pass frequency. Bass EQ: This setting is a fixed bass boost at 45Hz that is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a low volume or a low recording quality as this can result in high distortion and possibly clipping. Low Pass: The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the Low Pass to 80Hz, the amplifier will not play frequencies above 80Hz but will play frequencies from 80Hz to the chosen Subsonic frequency. Level Control Setup: Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input sensitivities properly to the head unit output signal level. It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual. If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts. If you are not sure what the Radio output sensitivity is, follow these general guide lines: Turn the level control up slowly, till you hear distortion, then back off a few degrees on the control. If at any point your amplifier goes into protection, you will need to turn the Level to the left a bit and then try again. If you reach a point where the output does not increase, stop turning the Level control to the right as the amplifier/subwoofer combo has reached its maxx output in this application. Sit back and enjoy the music! HFi100.2 / HFi55.4 / HFi100.4 General: At this point you are ready to get more specific on the settings for your amplifier. High Pass: -When in Hi Pass operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock position is a great starting point. EXAMPLE: If you ad...
