  • Page 2: Unpacking And Installation

    UNPACKING AND INSTALLATION Although it is neither complicated to install nor difficult to operate your Power Amplifier, a few minutes of your time is required to read this manual for a properly wired installation and becoming familiar with its many features and how to use them.
  • Page 3 HIGH EFFICIENCY CIRCUIT TYPE High efficient 3-step(S4000) output circuit for lower AC current consumption and advanced thermal performance. (S3000:2-step output circuit) VARIOUS LED INDICATORS To confirm the operating status, LED display of Power, Stand-By, Signal, Level, Clip and Protection on front panel.

    6. CLIP-LIMITER INDICATORS The clip-limiter indicators turn on when a distortion level above 1% THD is present in the output. 7. CLIP-LIMITER SWITCHES Use this to prevent the amplifier from continuous clipping in each channel output. 8. STAND-BY INDICATOR The stand-by indicator turns on when the stand-by switch (2p screw terminal) on rear panel turned on. 9 PROTECTION INDICATOR The protection indicator turns on when a protection circuit in the amplifier is operating by an abnormal condition as follows.

FAN Continuously variable speed fan is operated by the thermal sensors on the main heatsink or the switching power transformer.
  • Page 9 STEREO MODE AND BRIDGED MONO MODE STEREO MODE In this mode, channels 1 and 2 operate independently (typical stereo amplifier). Channel 1 input signal feeds channel 1 power amp, and channel 2 input signal feeds channel 2 power amp. In this mode, the minimum speaker impedance per channel is 4Ω.

    CAUTION FOR SPEAKER CONNECTION AND INSTALLATION 1. Turn off the POWER switch. 2. After removing approx. 10mm of insulation from the ends of the speaker cables, pass the bartends of the speaker wires through the holes in the corresponding speaker terminals and tighten the terminals to securely clamp the wires.
