9. Warranty and Liability
Two years full warranty on all supplied materials, workmanship and early failure in
normal and moderate use, from date of delivery, with the following conditions:
Mechanical damages due to non-careful handling, transportation (after delivery),
excessive environmental conditions, etc. are excluded from warranty.
In case of a need of service under warranty or other, the client is responsible for
shipment to and from Qsources in Belgium, insure that the shipment does not
incur taxes or other charges for the incoming and return shipment.
Qsources is not liable for any damage directly or indirectly resulting from the use
of the amplifier, regardless whether the damage occurs to the customer, to prop-
erty of the customer, to a third party or to the property of a third party.
This is electronic measurement equipement that requires care in handling and shipping.
10. Questions and answers
How long does it take the temperature protection to reset?
The internal modules have to cool down considerably before restart, and this will be
much faster in 15 Celsius, then in 35 degrees Celsius. But in normal working conditions it
can take up to 30 miuntes before this safety resets.
I use an external signal, but the amplifier does not give much power, or it shuts down
when trying to use this.
Sometimes an external signal device will generate signals outside the normal band (20-
20000 Hz) of the amplifier. This is not always obvious. For example; digitalization noise
at 50 Khz, or residual DC content, or residual 50/60 Hz. This may cause the amplifier to
shut down, or to limit the power in the normal band. Some protective filtering is
provided internally in the amplifier, but it is best to filter out of band signal before
entering the Qam amplifier.
When using an external input signal, could I damage the amplifier or the sources?
The amplifier input will withstand any type of normal signal coming from any
measurement device or computer on the headphone outlet. The output of the Qam
amplifier will just try to follow the input signal up to ss 0.35V.
