Content | As a part of APartʼs revolutionary series of convection cooled power amplifiers, Champ-4 is an amplifier without cooling fans. Its four discrete AB-class amplifiers deliver high quality musical sound, high dynamics, and high reliability - all in a one-unit 19” enclosure.
No fan
Power amplifiers have to operate in demanding circumstances. Places where the air is full of dust, nicotine or grease. Because power generates heat, power amplifiers typically have fans to keep their electronic circuits cool. Unfortunately, these cooling fans are a major headache in the use of high-power amplifiers. They tend to be noisy, and if -or rather, when- the fan breaks down because of dust collection, the amplifier overheats and ultimately fails. A fanless amplifier seems the logical thing, but -until now-, the idea never seemed to work for high quality amps with high output power. Thus, installers stick to fan-cooled models and get out of bed to replace a fried amplifier ….
Unique design
Especially for the CHAMP-series, APart introduces unique, custom-designed side mount heat sinks. In combination with a self-supporting low resonance frame, they make it possible to create a discrete power amplifier without a noisy and dust-collecting fan inside the enclosure. This means: less maintenance, no annual fan or dust filter exchange procedure, no more amplifier cleanout, and no more unwanted noise from cooling fans. Because of this, Champ-4 can rely on convection cooling only! Champ-4 has a torsion-free front in solid brushed aluminum. The removable brackets have a special fixation system that allows easy removal but still assures extraordinary-strength fixation. This makes it possible to use the unit rack mounted as well as freestanding. On the rear side of the unit the user will find solid binding posts and 4 sets banana screw plugs included.
APC power management circuitry gets the best out of an amplifier
APC power management circuitry has been designed especially for Champ series amplifiers. It is one of the most intelligent amplifier protection circuits ever designed, simply because it does the job without interfering with the typical dynamic character of music. APC allows the user to preset the power potential of the amplifier, while maintaining high power reserves and thus producing high, clean power. It constantly analyses incoming music signals and keeps dynamics alive. An additional ultra fast peak limiter avoids amplifier clipping. With APC, your system is always in control, including your speakers.
Bridging amplifiers and bridging channels
It is possible to bridge two channels of the Champ-4. By doing this you unite the power of two smaller amplifier channels into a more powerful amplifier channel. The resulting power is usually more than double the power of both amplifiers used individually with the same load. Check the user manual for instructions on how to proceed. Champ-4 is a four-channel amplifier. If you want to use a subwoofer, it is possible to bridge two of the channels for use as a subwoofer channel. The two remaining channels can be used for the top speakers.
It is the ideal solution to create a small music system for small dance floors or parties. As it is equipped with a X-over, you end up having a superior, yet easy-to-use sound system. The striking design and technical innovations of the Champ series are setting new industry standards….whether it is for AV, studio, gigs, home or catering applications: experience the pure musical power of CHAMP-4!

The C 16:4 is one of two mid-power, four-channel amplifiers in the C Series family. Attractively packaged in a 2U chassis, it provides 4 × 400 W output into 4 ohm loads.
C Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL™), which allows the output to be optimized for any loudspeaker load – whether a single large subwoofer or a series of small 100/70 V loudspeakers. VPL works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.
Every C Series is ready for the NomadLink® network right out of the box. With NomadLink, key amplifier parameters are displayed via DeviceControl software, and remote control of channel mutes and power on/off is under network control.

Note 1): Automatic -6 dB gain compensation when bridging channels. Ch.’s A+B and/or C+D, can be bridged individually.
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.
Refer to Operation Manual.
Note 3): For sine waves, peak voltage output values translate to Vrms with the formula V/1.41 = Vrms. E.g. 100 V peak equals app. 70 Vrms.
Hence, outputs can be set for high-impedance loads without requiring a transformer.
