User manual HELIX P10 DATASHEET

[. . . ] 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. [. . . ] In the case of service note the following: 1) The 2 years warranty period commences with the purchase of the product and is applicable only to the original owner. 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. Thus every desired Bandpass between 15 Hz and 4000 Hz can be adjusted. 7 6 8 9 18 19 20 5 4 12 10 11 14 15 16 17 13 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). If a subwoofer is connected we recommend to use highpass control 21 as variable subsonic filter or to turn control 21 counter-clockwise to 15 Hz to get a subsonic filter. 11 Mono/Bridged/Stereo selector To set the operating mode of the amplifier. Stereo: If the amplifier operates in 2-channel mode the switch has to be set on stereo position and both inputs (6 and 7) must be used. Bridged: If the amplifier operates in Mono mode the switch has to be set on Bridged position. In this case both channels works as one (Mono) channel. On the position "Bridged" both inputs A and B (6 and 7) must be used. Mono: As on position "Bridged" the amplifier operates in Mono mode were both channels works as one (Mono) channel. [. . . ] 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. 14 Frequency level control for highpass of CH A and B Control for the adjustment of the crossover frequency from 15Hz to 4 kHz. 17 Adjustment of center frequencies Control 17 can be used to select the frequency from 40 - 120 Hz of the adjusted lowpass.
