- LOW PASS: N/A Interconnect cable checklist: Channels 3/4: - Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables. - HI PASS: N/A - LOW PASS: N/A Switch setting checklist: - 1/2CH X-OVER: FULL Level control checklist: - 3/4CH X-OVER: FULL - Refer to the section “Setting up systems after installation for best performance” Crossover frequency control checklist: Minimum final loudspeaker impedances: Channels 1/2: - 2 ohm per channel. Here we show how to use the 4 channel amplifiers as a 3 channel unit by taking Switch setting checklist: advantage of the mono bridging capability of all Hifonics amplifiers. - 1/2CH X-OVER: FULL - 3/4CH X-OVER: LPF The following example shows how to create a 3 channel system by mono bridging channel pair 3 / 4. In order to create a 2 channel system, simply follow Crossover frequency control checklist: the example to also mono bridge channel pair 1 / 2. Channels 1/2: - HI PASS: N/A Interconnect cable checklist: - LOW PASS: N/A - Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit with good quality RCA cables. Channels 3/4: - A MONO signal source is required to bridge channel pair 3/4, such as would be - HI PASS: N/A available from the mono sub bass output of an active crossover, whether - LPF: 11 o’clock standalone, or built into a head unit or equalizer. If you only have 1 set of RCA outputs from your headunit, you can simply connect those to the inputs for ch TIP: If you are using the mono sub bass output of an active crossover, there is 1/2 and switch the MODE to 3ch. The amplifier will auto sum the signal and nothing wrong with switching in the low pass filter in these amplifiers for a provide mono output for bridged channels 3/4. steeper low pass rolloff. Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the Level control checklist: output stage of that source. - Refer to the section “Setting up systems after installation for best performance” - It is necessary to feed the SAME signal to both left and right inputs via a Yadapter RCA cable. Minimum final loudspeaker impedances: - Connect the mono speaker positive terminal to the RIGHT +, and its negative - 2 ohm per channel in stereo mode. terminal to LEFT - as shown. - 4 ohm mono bridged. 4 LINE O UT CH3/4 CH1/2 L L R R 6V 0 . 2 V 0 dB 1 2d B F ULL LPF HPF 6 0 Hz 12 KHz 30 Hz 25 0 Hz LEVEL B A SS EQ XOVER HPF LPF 6V 0 . 2 V 0 dB 1 2d B F ULL LPF HPF 6 0 Hz 12 KHz 30 Hz 25 0 Hz 2 3 4 LEVEL B A SS EQ XOVER HPF LPF MOD E PO WER PRO TECT P O W E R I N P U T G N D R E M B A T T + 1 2 V C H 1 / 2 S P E A K E R O U T P U T C H 3 / 4 R I G H T L E F T R I G H T L E F T - + - + - + - + B R I D G E D B R I D G E D F U S E HF LINE O UT CH3/4 CH1/2 L L R R 6V 0 .2 V 0 dB 1 2d B F UL L LPF HPF 60 Hz 12 KHz 30 Hz 250 Hz LEVEL B A SS EQ XOVER H PF LPF 6V 0 .2 V 0 dB 1 2d B F UL L LPF HPF 60 Hz 12 KHz 30 Hz 250 Hz 2 3 4 LEVEL B A SS EQ XOVER H PF LPF MOD E PO WER PRO TECT P O W E R I N P U T G N D R E M B A T T + 1 2 V C H 1 / 2 S P E A K E R O U T P U T C H 3 / 4 R I G H T L E F T R I G H T L E F T - + - + - + - + B R I D G E D B R I D G E D F U S E HF STEREO LINE INPUT MONO LINE INPUT (Unless using procedure listed above for 3ch) HFi55.4 / HFi100.4 4-CHANNEL AMPLIFIER APPLICATIONS 5 Front/Rear high pass, using a 2 channel amplifier for mono sub bass The combination of a 2 and a 4 channel amplifier, utilizing their built in Channels 1/2: crossovers, makes it a snap to put together a full system with front and rear - HI PASS: 100 Hz highs, with mono sub bass.
