Problems and Remedies
Why is there no sound from the speakers?
- Check that input and output cables are secure at both ends.
- Make sure your Halo Integrated is switched to the correct input.
- If you are using the USB input with a Windows
®
computer you must first install the drivers.
The Halo Integrated won’t turn on
- Make sure the rear panel Turn On Options Switch is set to the Manual position.
- Is the AC mains power live? You should see a faint blue glow around the On-Off button even
when the unit is turned off.
- Make sure the rear panel master power switch is turned on.
The Halo Integrated won’t turn off
- Make sure the rear panel Turn On Options Switch is set to the Manual position.
The On-Off button is glowing red
- The unit’s protection circuits have been activated, see page 21 for more details.
- Check the speaker wire and connections for a short circuit.
- If the unit feels hot allow it to cool down and provide more ventilation for the unit.
I can hear a background hum from the speakers
- Try unplugging the incoming Cable TV line. If the noise goes away you need a cable TV
ground isolator.
- Read the section on ground loops in this manual.
- Move audio cables and AC cords away from each other (while power is off).
- Try to route audio cables and AC cords perpendicular to each other (while power is off).
- Make sure insulating shoulder washers are used if unit is rack mounted.
- Insure that the power amps and the Halo Integrated are plugged into the same AC outlet.
- Try plugging your subwoofer into the same AC mains outlet as the Halo Integrated.
- The turntable ground wire must be attached to the GND terminal.
When I use the Bypass/Amp Input the sound is very loud and cannot be turned
down.
The Bypass/Amp input should never be connected directly to a source component (CD, DVD,
Tape deck, etc.). It should only be used in conjunction with a surround sound receiver or
processor. The volume control on the surround sound receiver or processor should be used to
adjust the volume level when the Bypass/Amp input is selected.
What is the Bypass/Amp Input?
The Bypass/Amp input jacks are used to incorporate the Halo Integrated into a surround
sound system. This enables you to use the power amplifier built into the Halo Integrated to
drive your Left and Right front speakers with both the stereo sources connected to the Halo
Integrated and with your surround sound system.
