Direct audio connections
This is the preferred method of connecting the amplifier to a TV and other audio products
(as opposed to using a microphone). It will deliver the clearest sound without background
noise affecting the clarity. The amplifier has both analog and digital audio inputs.
Digital Optical TOS link and Coaxial outputs are found on most TVs and Audio Equipment.
These connections will provide the clearest sound input to your system. You may need to
alter the settings of the digital audio output on your TV to "PCM" so that the digital audio
output signal matches the loop amplifier.
Analog audio connections use the red, white RCA Audio connectors on the loop amplifier.
These analog audio connections are very common on all types of equipment.
Multiple pieces of equipment may be connected to the loop amplifier at any one time:
• One digital source using either TOSlink or Coaxial but NOT both at the same time
• One or two pieces of analog equipment using the analog audio inputs
• One or two microphones
The sources may be switched by using the input buttons on the front of the unit or by
using the remote control. One microphone (Microphone B) can override all other sources
by depressing the priority switch on the back of the unit.
Note when using a television as a source, and using the TV's headphone jack output,
this connection may disable the television speaker from working. On some TVs there
is a setup option in the TV menu that allows the TV speaker to keep working while the
headphone jack is being used.
