9 TECHNICAL SPECIFICATIONS

Following are the 10K4 technical specifications. These figures are accurate at the time of printing but please note
that all figures are subject to change without notice. For the most accurate and current information available,

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 2Ω 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 2Ω 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.
