We got inspired to make something APart from all the rest, and started from scratch. Take a look at our new champion with his striking design and powerful set of features that will exceed the demands of passionate music lovers as well as system integrators. Designed with a... - Page 4 • H igh current, high voltage discrete output stage in class G and H configuration, capable of driv- ing even the most demanding speaker systems and combinations. Either at low or high power, Champ-One you will hear the difference. • Switchable “tube” characteristic is a unique feature on discrete power amps. It allows you to enjoy a warm, softer, more transparent sound resulting in zero listening fatigue.
- Page 5 We have done our best to make sure this amplifier will produce clean power, but it is also the user who is responsible for the final result. • V ersatile in- and output connector configuration for increased installation flexibility. • User protected power and sound setting switches at the rear, accessible behind a removable cover plate. • G round lift switch to enable you to find the cause of system ground loops.

APC circuit (rear switch ‘15’) will also turn off this protection feature and will void warranty. When both signal led (1) and temp led (4) are red, it is possible that the power transformer’s thermal protection is active and the amplifier is shut down. Turn off the power and let it cool down. The amplifier will not turn on automatically after it has cooled down, the user MUST turn off power, wait for cooling down and then power on again ! 5) P ower switch and power led: flip the switch to power on the amplifier. The led will light up to indicate that mains power is present. INFO@APART-AUDIO.COM... - Page 8 APC circuit (rear switch ‘11’) will also turn off this protection feature and will void warranty.

The intelligent APC circuitry will reduce input gain and level to a safe margin within certain limits. This circuitry can not correct an input signal that is already clipped and distorted. INFO@APART-AUDIO.COM... - Page 10 6) R ight channel input level control: turn the level control to a level that guarantees distortion free music under all circumstances, avoid clipping at the input at all costs ! 7) A PC active led right channel, this is a copy of the front panel APC led. 8) R ight unbalanced input on cinch connectors: use the top or bottom cinch connector to apply an unbalanced signal on the right channel. These connectors are wired in parallel, this means you can use the second connector as a signal link connector. 9) R ight balanced input on XLR connector, this connector is wired in parallel to connector ‘10’. This allows you to link the balanced signal to another amplifier. WWW.APART-AUDIO.COM...
- Page 11 21) B ridge mode switch: push this switch to convert the amplifier into a mono bridge amplifier. In this case you can apply an input signal to the left channel only ! Leave the right channel connectors open ! Bridge mode input level is controlled by the left channel level controller (‘20’) only. Connect your speaker to the right channel +(plus) connector and to the left channel +(plus) connector ! Never use the speaker output –(minus) connectors in bridge mode ! The led above the bridge mode switch will indicate that the amplifier is in bridge mode. Minimum bridge mode speaker load is 8 ohms. INFO@APART-AUDIO.COM...
- Page 12 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. The amplifier may not be able to meet the specifications when installed in a poorly ventilated environment. Support the unit at the rear when installing in a rack ! Always remember: excessive heat is one of your amplifier’s biggest enemies !
