Home Theater Bypass Mode
Each of the HA-1’s input sources can be individually configured to operate in a Home Theater Bypass mode. If an
input source is in this mode, the HA-1’s volume control is bypassed for the Pre-Amplifier Output. The Pre-Amplifier
Output level will be exactly the same as the input signal level (unity gain). This feature helps when integrating the HA-1
as a high performance stereo pre-amplifier into a multi-channel home theater sound system. The following diagram
shows the typical connection for such a system:
In the above system, when listening to stereo sources (such as the CD player), only the stereo power amplifier, the HA-
1 and the source component need to be turned on. Volume is controlled by the HA-1. When listening to multi-channel
sources, all components are turned on, and the volume is controlled by the surround sound processor. The HA-1’s
input source that is connected to the surround sound processor (RCA Stereo Audio Input in this example) is
configured in Home Theater Bypass mode. The HA-1’s Pre-Amplifier Output level will be exactly the same as the
output level of the surround sound processor’s front left and right channel output levels because the volume control of
the HA-1 is bypassed.
