Exposure to extremely high noise levels may cause a permanent hearing loss.
Introduction Dear customer, Why does live music leave an unforgettable impression on you ? The answer is simple: dynamics. The ability of a sound system to produce crystal clear low level sounds as well as extreme musical peaks without any distortion, the power to leave some headroom for those occasional peaks in music. Pure power ! This ease of music reproduction can not be described in figures or specifications. In the following pages we will explain how we have reached our goal.
1. Fanless design and highlights • Audiophile grade components mounted on solid aluminum and steel construction chassis for the highest possible signal integrity and reliability, even under difficult circumstances. • High current, high voltage discrete output stage in class G and H configuration, capable of driving even the most demanding speaker systems and combinations. Either at low or high power, you will hear the Champ-One difference.
2. Features • Intelligent APC power management circuitry constantly analyses incoming music signals and keeps dynamics alive. An additional ultra fast peak limiter avoids amplifier clipping in case someone hits the inputs too hard. Please remember, this is a musical amplifier, please leave some headroom and enjoy the music. • APC also allows you to configure the amplifier to your specific needs: average RMS output power is programmable from 150 to 600 watts.
What is APC ? APC 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 you to fully exploit the potential of the amplifier, maintaining high power reserves and thus producing high, clean power. It is a common misunderstanding that high power amplifiers will overload or destroy lower power speakers, the opposite is true.
3. Inputs and outputs Front panel layout: 1 2 3 4 5 6 7 8 9 1) Signal led left channel, this led lights up green when a sufficiently strong signal is present on the left channel, after passing the input level control. When it lights up red, the power amp is overheated or in protect mode and is shut down. Turn off the power.
6) Signal led right channel, this led lights up green when a sufficiently strong signal is present on the right channel, after passing the input level control. When it lights up red, the power amp is overheated or in protect mode and is shut down. Turn off the power.
Led status messages Fault condition SGL led L = red Left amp temp high Temp led L = red SGL led R = red Yes Right amp temp high Left amp overheated Temp led R = red Yes Yes Yes Right amp overheated Yes Yes What to do ?

Rear panel layout: 1 6 7 8 9 10 2 11 12 3 13 14 4 15 5 16 17 18 19 20 21 1) Right speaker output on genuine Neutrik® Speakon connectors. Only pin 1+ and 1- are used here. 2) Right speaker cable binding posts, these will also accept 4 mm banana plugs on 19 mm spacing. 3) Left speaker cable binding posts, these will also accept 4 mm banana plugs on 19 mm spacing. 4) Left speaker output on genuine Neutrik® Speakon connectors.
10) Right balanced input on XLR connector, this connector is wired in parallel to connector ‘9’. This allows you to link the balanced signal to another amplifier. 11) APC right channel on/off switch: always leave this switched on. Warning: turning off the APC circuit will also bypass the amplifier’s output stage temperature protection. This is for service purposes only. 12) APC power control right channel: turn the APC control to achieve the desired program output power.
4. Rack mounting and wiring Champ-One can be mounted in a 19” rack, taking up only 2 rack spaces. Always allow a good airflow around the amplifier’s front, rear, side, top and bottom. When installing in a rack with multiple audio devices, it is advisable to leave one rack space between units. Fill the empty rack spaces with meshed blind panels for improved ventilation. Never mount the amplifier in a sealed cabinet, unless adequate forced ventilation is provided.
5. Standalone use It is possible to integrate Champ-One in a high quality audio chain. In order to adapt the front panel dimensions to the dimensions of other equipment, it is possible to remove the 19” brackets and handles for an even more sleek and refined look. Remove the three screws marked in the circles and slide off the handles. 13 INFO@APART-AUDIO.
