1. Power Light: This light will turn on when Zone Power Eight is powered on.
2. Signal/Clip/Protection LEDs: Each column of three LEDs shows the signal status of the
corresponding Channel Input (labeled on the front panel as CH1-8):
• Clip LED (CLIP): When the Clip LED is lit red, the input’s signal is “peaking” (higher than
0 dB). To prevent the “clipping” (distortion) that can result from a loud input signal, turn
the input’s volume knob (on the rear panel) counter-clockwise or reduce the volume on
the device plugged into the input.
• Signal LED (SIG): The Signal LED will be lit green when the signal coming from the
input is at an optimal volume level.
• Protection LED (PROT): If the Protection LED turns red, Zone Power Eight is in heat
protection mode and will not output sound. To restore sound output, reduce Zone Power
Eight’s temperature by making sure there is good ventilation and/or decreasing the input
volume.
3. Air Intake Vents: Keep these vents clear from obstructions to allow air to flow through the
front grill for proper performance.

1. Power Input: Use the included power cable to connect this input to a power outlet.
2. Fuse: If the unit’s fuse is broken, lift this tab to replace the fuse. Replace it with a fuse with
an appropriate rating. Using a fuse with an incorrect rating can damage the unit and/or fuse.
3. Exhaust Vents:Air from the front intake flows through the unit and exits here. For proper
performance, do not block the air vents.
4. Channel Inputs with Volume Knobs (Input 1-8): Use Euroblock connectors to connect
these inputs to your audio sources. Each channel has a volume knob that you can use to
raise or lower the signal coming from your audio source. See Setup for more instructions.
5. Channel Outputs (CH1-8): Use Euroblock connectors to connect these outputs to your
loudspeakers. Each output sends the amplified signal from the corresponding Channel
Input to the connected loudspeaker. See Setup for more instructions.
Note: Use only 70V/100V speakers designed with step-down transformers. Using low
impedance 4Ω/8Ωspeakers on 70V/100V outputs will overload and possibly damage this
amplifier.
6. Operation Mode Switches:To set a Channel Output’s operation mode in accord with
the speaker connected to it, adjust the corresponding switch (1-8) to 70V or 100V.
