Page 11: Set Up And Operation
Set Up and Operation Installation Remove all packing materials from the Stage Amp. Check that all foam and plastic padding is removed. Secure the equipment into a 19" rack. Connect all cables. Connecting Power / Circuit Size Requirements. The actual current draw, the amplifier demands from the AC mains, depends on many factors (its load, output level or the crest factor of its program material). -
Page 12: Mode Selection
Mode Selection The three-position, recessed Mode Select switch (located on the rear panel) configures the amplifier for Stereo, Parallel or Bridged Mono Mode. Amplifiers are factory set to Stereo Mode. Stereo Mode In Stereo Mode, both channels operate independently, with their input attenuators controlling their respective levels. -
Page 13: Bridged Mono Mode
Bridged Mono Mode Bridged Mono Mode straps both amplifier channels together to make a very powerful, single-channel monaural amplifier. One channel "pushes" and the other "pulls" equally, doubling the power over that of channel alone. Signal is applied to the Channel A input only. Both attenuators are used to control signal level;... -
Page 14: Reliability Protection Function
Reliability protection function 1. Clip/Limit This feature has two protection functions: 1) Limit on the input signal range, to prevent input signal overload beyond the amplifiers rated range and cause square wave output to damage the speaker. 2) When the signal waveform is distorted, it can automatically adjust gain and limit distortion signal output. -
Page 15: Connection Cables
Connection Cables Take care of the connector cables, always holding them by the connectors and avoiding knots and twists when coiling them: This gives the advantage of increasing their life and reliability, which is always to your advantage. Periodically check that your cables are in good condition, that they are correctly wired and that all their contacts are in good condition: a great number of problems (faulty contacts, ground hum, discharges, etc.) are caused entirely by using unsuitable or faulty cables. -
Page 16: Maintenance
Maintenance DAP Audio STAGE AMP requires almost no maintenance. However, you should keep the unit clean. Disconnect the mains power supply, and then wipe the cover with a damp cloth. Do not immerse in liquid. Do not use alcohol or solvents. Keep connections clean. -
