Important informations for connecting loudspeakers
Die Helix A4 Competition has 4 integrated power ampli-
fiers. Each of them is 1 ohm stable. That means a loud-
speaker impedance can be connected on each channel. In
bridged mode two each amplifiers are working together
as one channel. In this case pay attention that each chan-
nel has to process half of the connected impedance.
Example: If a 4 ohms loudspeaker is connected to a brid-
ged amplifier, it means 2 ohms for each channel and so
1 ohm with a 2 ohms loudspeaker. Therefore 2 ohms is
the lowest impedance that can be connected to a bridged
pair of channels, because each single channel is 1 ohm
stable. Do not run all channels with an impedance of 1
ohm because the total current is getting too high. In this
case it can be that the calculated total power of the
amplifier is going beyond and the input fuse or the
amplifier will be destroyed. It makes no sence to connect
one ohm on all channels because the total loss of power
will be too high, that means the power will not be trans-
mitted by the loudspeaker, it will convert into heat wit-
hin the amplifier.
To ensure proper function of the A4 Competition ampli-
fier please pay attention on the following rules:
1. The total impedance of all connected loudspeakers
on all channels should not be lower than 6 ohms, no
matter if a pair of channel is bridged or not.
Some examples:
4 x 1.5 ohms or
1 x 2 ohms (bridged) + 2 x 2 ohms or
2 x 1 ohm + 1 x 4 ohms (bridged) or
2 x 3 ohms (bridged) etc.
The total impedance of all examples is not lower than 6
ohms.
If two 2 ohms woofer are connected (total 4 ohms) on
two bridged channels or 4 1 ohm loudspeaker (total 4
ohms) are connected on each channel and the total impe-
dance is below 6 ohms the amplifier can shut off, the
fuses can burn or the amplifier can be destroyed.
2. The impedance per channel should not be lower
than 1 ohm.
We guarantee a lot of pleasure with the A4 Competition
if you take notice of this informations.

Warranty Regulation

Due to the high quality standard Helix products achie-
ved an excellent international reputation. Therefore we
grant a warranty period of 2 years.
The products checked and tested carefully during the
entire production process. 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 repairing the defective part at our decission.
Further claims, and in particular those for price
reduction, cancellation of sale, compensation for
damages or subsequential 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 invali-
date this warranty.
4) Consult your authorized dealerr 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 concea-
