Yours AUDIOTEC FISCHER Team General installation instructions for HELIX amplifiers Before you start installation, disconnect the car battery at the minus pole. [. . . ] In order to ensure safe installation, use only high-quality connections and materials. Ask your dealer for HELIX accessories. HELIX Cross Cards (HCCs) HCC1 is inserted as standard in every HELIX ESPRIT amplifier. To expand the operation range of your HELIX amplifier, your dealer will provide the following HCCs as optional equipment: Valid for all modules: low pass: red LED is on high pass: yellow LED is on full range: green LED is on bandpass: red and yellow LEDs are on (switch position "low pass") HP1 LP1 LP2 Crosscards HCC HP2 85 Hz HP/LP 85 Hz HP/LP incl. subsonic LP: 60-500 Hz / HP: 60-700 Hz LP: 300 Hz-5 kHz / HP: 500 Hz-7 kHz LP: 300 Hz-5 kHz / HP: 60-700 Hz for bandpass HCC 6 LP: 120-250 Hz / HP: 60-90 Hz for bandpass (kickbass) HCC 1 HCC 2 HCC 3 HCC 4 HCC 5 HCC 3 90 70 110 170 60 Hz 500 Pot. : LP1/LP2 100 70 150 250 60 Hz 700 Pot. : HP1/HP2 HCC 1 HCC 5 500 400 750 1, 3K 300 Hz 5K HCC 2 Pot. : LP1/LP2 100 70 150 250 60 Hz 700 Pot. : HP1/HP2 10 H 400 ESPRIT 5 - 8 Signal inputs The H 400 ESPRIT has RCA connections for cinch cables leading from the pre-amplifier outputs, the line outputs of the head unit or the outputs of a pre-amplifier/equalizer, e. g. These connectors are gold-plated in order to ensure better signal transmission. 9 - 12 Level controls for input sensitivity These controls can be used to match the input sensitivity of the individual channels - A to D - to the output voltage of the connected head unit. These controls are not volume controls and are solely intended for the purpose of sensitivity trimming. The control range extends from 330 mV to 8, 4 V. 750 1, 3K 300 Hz 5K Pot. : LP1/LP2 These have the following meanings for all modules: yellow = high pass green = full range red = low pass red and yellow = band pass If required the plug-in frequency crossover modules are available with a 28 Hz/18 dB Oct. 19 Speaker connection terminals for channels A and B 20 Speaker connection terminals for channels C and D 21 - 23 CPS-Color Protection System The LEDs show the operation status of the amp. Green = O. K. ; yellow = the speakers wires are shorted to ground; red = over heated. If the amp shuts off due to overheating it will take some time (depending on the outside temperature) until it switches on again. Important notice Never connect the speaker wires to the chassis of the vehicle. All speaker systems must be connencted in-phase, this means plus to plus and minus to minus. The plus pole is normally marked on the speaker. In addition, the amplifire can operate channels A and B as well as C and D in stereo or mono mode (bridged). Besides from stereo and mono mode, the amp can be connected for tri-mode use, which means that two stereo speakers can be operated with one pair of wires (AB or CD) and have a third speaker connected in mono mode. Please see basic instruction sheet for various speaker connections. Technical specifications see page 16. HCC 4 500 400 1 Connecting the remote lead The remote lead is connected to the automatic antenna (aerial positive) output of the head unit (radio). This is only activated if the head unit is switched ON. Thus the amplifier is switched on and off with the head unit.
