User manual HELIX HXS 636 AVANTGARDE INSTALLATION

[. . . ] Any other system could cause damage to the amplifier and the electrical system of the vehicle. The plus cable from the battery for the complete system should be provided with a main fuse at a distance of max. The value of the fuse is calculated from the maximum total current input of the car audio system. Install the cabling in a manner which precludes any danger of the leads being exposed to shear, crushing or rupture forces. [. . . ] 2) During the warranty period we will rectify any defects due to faulty material or workmanship by replacing or repai ring the defective part at our decission. Further claims, and in particular those for price reduction, cancellation of sale, compensation for damages or subse quential damages, are excluded. The warranty period is not altered by the fact that we have carried out warranty work. 3) Unauthorized tampering with the product will invalidate this warranty. 4) Consult your authorized dealer first, if warranty service is needed. Should it be necessary to return the product to the factory, please insure that a) the product is packed in original factory packing in good condition b) the warranty card has been filled out and attached to the product c) the product is shipped prepaid, i. e. at your expense and risk d) the receipt/invoice as proof of purchase is enclosed 5) Excluded from the warranty are: a) Shipping damages, either readily apparent or concealed (claims for such damages must be immediately notified to the forwarding agent). b) Scratches in metal parts, front panels or covers etc. This must be notified to your dealer within 5 days of purchase. c) Defects caused by incorrect installation or connection, by operation errors, by overloading or by external force. d) Products which have been repaired incorrectly or modified or where the product has been opened by other persons than us. With control 21 adjust the highpass and with control 22 adjust the lowpass. Thus every desired Bandpass between 15 Hz and 4000 Hz can be adjusted. 16 Selector switch for channels C and D To switch the internal active crossover to highpass/full range (linear) or lowpass. If this switch is set on Highpass the exactly frequency can be set with control No. At switch position Lowpass/Bandpass the highpass is always active. That means a Bandpass is built in any case. With control 23 adjust the highpass and with control 24 adjust the lowpass. Thus every desired Bandpass between 15 Hz and 4000 Hz can be adjusted. 9 8 7 6 14 3 2 1 A B 10 11 12 13 25 26 27 5 4 15 16 17 21 22 23 24 18 A B A 19 B A B C 20 D 1 2 3 4 5 6-9 10-13 14 15 Connecting the remote lead Connecting the battery cable Connecting the ground cable Fuses 3 x 25 Ampere Fuse function indication Signal inputs Level controls for input sensitivity Signal input selector Selector switch for channels A and B 16 17-18 19 20 21 22 23 24 25-27 Selector switch for channels C and D Mono/Stereo selector Speaker terminals for CH A and B Speaker terminals for CH C and D Frequency control highpass A and B Frequency control lowpass A and B Frequency control highpass C and D Frequency control lowpass C and D Colour protection system Caution!To avoid a lost of sound pressure make sure that the crossover frequencies of high- and lopass are separated of 2 octaves when building a Bandpass. That means: If the lowpass signal is adjusted to 320 Hz the highpass should be adjusted 2 octaves lower on approx. 80 Hz (1 octave=double frequency or half frequency). [. . . ] All speaker systems must be connected in-phase, this means plus to plus and minus to minus. The plus pole is normally marked on the speaker. In addition, the amplifier can operate channels A and B as well as C and D in stereo or mono mode. The amp also can be connected for tri-mode use with one pair of wires (AB or CD) and have a third speaker connected in mono mode. [. . . ]
