1 General Information
Warranty service is effective and available to the original purchaser only.
To obtain service under this warranty, the product must, on discovery of the defect, be properly packed and
shipped to the nearest Bittner Audio dealer. The party requesting service must provide proof of original
ownership and date of purchase of the product.
If the warranty is valid, Bittner Audio will, without charge for parts or labor, either repair or replace the
defective parts. Without a valid warranty, the entire cost of the repair is the responsibility of the product’s
owner.
The warranty does not cover defects or repairs needed as a result of:
1. Damage caused by abuse, accident, or negligence.
2. Damage caused by any tampering, alteration, or modification of the product or its components.
3. Damage caused by failure to maintain and operate the product in strict accordance to the written
instruction of this operating manual.
4. Damage caused by repairs or attempted repairs by unauthorized persons.
5. Damage caused by fire, water and other natural events.
6. Damage caused by operation on improper voltages.
1.7 Packaging
Upon unpacking, please inspect the product. If you find any damage, notify your supplier immediately. Be
sure to save the carton and all packing materials in case you have to send the product to the supplier.
Please use only the original factory packing. If the shipment carton is unavailable, contact Bittner Audio
International GmbH (www.bittner-audio.com) to obtain a replacement.
1.8 Air Ventilation & Cooling Requirements
The devices are equipped with a forced air-cooling system with variable speed and temperature controlled
fans to guarantee low operating temperature and minimal ventilation noise. The air flow takes place from
the rear to the front of the amplifier. The air-pulling fans are installed on the back side of the unit. The air
flow is always from the front to the rear side.
In case a heat sink becomes too hot, the temperature sensor opens the respective output relay, disconnecting
the output load from the particular channel. In case the power transformer gets overheated, a different
sensor causes the output relays on all channels to open and to interrupt the outputs. After cooling down to
an appropriate operating temperature level the relay contacts are closed again automatically.
It is important to have adequate air ventilation space behind the amplifier to allow a proper air flow. In case
the amplifier is mounted inside a closed rack, do not cover the front of the rack with doors. If using racks
with a closed backside, use fans on the rear rack panel. Bittner Audio recommends one open rack space for
every 2 mounted power amplifiers.
