8 APPENDIX
8.1 Maintenance
During normal operation your 13K2 amplifier will provide trouble-free service. The only user maintenance required
is to periodically vacuum clean the foam dust-filters behind the front grille.
In some extreme cases it may be necessary for authorized service personnel to clean the inside of the amplifier.
These conditions usually occur after prolonged use in extreme environments such as those using cracked oil,
smoke machines. If you are using y our amplifier in a heavy-duty application, it is recommended to have your
amplifier serviced at regular intervals purely as a preventative action.
9 TECHNICAL SPECIFICATIONS

The Zenith amplifier range has been designed and engineered to work in demanding environments including
installation and touring with military endurance. Oversized multi-speed fans and large heat sinks improve heat
dissipation, while the SMPSU optimises the amplifiers efficiency while reducing the weight. The 10K4 and 13K2
lightweight power amplifiers from Zenith feature high efficiency TD class technology for high power output to
weight ratio, and are housed within compact 2U chassis. With up to 6500W per channel these power amplifiers
are ideal for rental or large installations. Suitable for driving into 2
Ω
loads, the amplifiers are equipped with an
extensive set of protection circuits for reliable operation.

Note 1: Automatic -6dB gain compensation when bridging channels.
Note 2: PAL can reduce the maximum output power to keep the power supply operating safely, and/or to prevent
excessive current draw tripping the mains breaker.
Note 3: The amplifier will be fully operational at bridge mode 2
Ω
loads, but due to physical constraints in the
construction, the max. output power will not be significantly higher than running individual channels and therefore
not stated here.
