Description
As part of Apart's revolutionary range of convection-cooled power amplifiers, Champ 4 is an amplifier that incorporates no cooling fans. Its four independent Class AB amplifiers deliver high-quality musical sound, excellent dynamics and high reliability, all in a 19" rack format.
Power amplifiers must operate in very harsh conditions, such as environments where the air is filled with dust, nicotine or grease. Since power generates heat, amplifiers normally use fans to keep the electronic circuits cool.
Unfortunately, these cooling fans are often the main problem with high-power amplifiers. They tend to be noisy and, when a fan fails due to dust accumulation, the amplifier overheats and eventually fails.
An amplifier without a fan seems like the most logical solution, but so far, this idea appears to have not worked in high-quality amplifiers with high output power.
Especially for the Champ range, Apart has introduced proprietary side radiators. In combination with its low-resonance chassis, it has been possible to create a power amplifier that produces no noise and does not accumulate dust inside.
As a result, the unit requires less maintenance, with no need for annual dust filter changes, and incorporates no fans that generate annoying noise. Champ 4 uses convection cooling only.
Champ 4 can be rack-mounted or placed on a desk; the unit features removable handles.
Threaded terminals and 4 sets of banana-type connectors are located on the rear of the unit.
The Champ 4 power amplifier features APC power management circuitry, which has been designed for this range of amplifiers. It is one of the smartest protection circuits designed to date, as it is able to perform its function without interfering with the dynamic character of the music.
APC allows the user to preset the amplifier's power while maintaining large power reserves and, consequently, delivering a clean sound at all times.
The circuit constantly analyzes the incoming musical program and keeps its dynamics alive. An additional ultra-fast peak limiter prevents the amplifier from clipping. With the help of APC, the entire audio system is kept under control, including the speakers.
Two Champ 4 amplifiers can be bridged. This combines two smaller amplifiers to obtain a larger amplifier. The resulting available power is normally more than double the power of the two amplifiers used individually with the same load.
Champ 4 is a four-channel amplifier. If a subwoofer is to be used, two of the channels can be bridged to use as a subwoofer channel. The remaining two channels can be used for the top speakers. This is the ideal solution for creating small musical systems for small dance floors or parties.
The range of applications for Champ 4 is very wide, from AV and studio applications and live performances to catering or home applications.
