Using IR Emitters
Each BreatheAudio System has the ability to control the audio source equipment attached to it, using IR (infrared) signals. This is the control signal
emitted by a wireless remote control. The 2430 package contains IR mouse emitters necessary for this kind of source function control. The
emitters plug into these outputs and are attached over the IR receiver of the source equipment. When the wireless remote control is aimed at the
keypad and one of the remote command buttons is pushed, that IR command is sent through the emitter and initiates that command for the source
equipment (fig. 7).
The 2430 System has two choices of IR outputs for each of the two audio source inputs. Some source components operate at a lower IR carrier
frequency (38,000 kHz), and some operate at a higher frequency (56,000 kHz). There is no way of knowing which output is appropriate, other
than the source equipment may be nonresponsive, or have sporadic responses to issued commands for the source equipment. If this occurs, it is
easily corrected by plugging the IR emitter into the other output. A general rule of thumb is that cable boxes and satellite TV receivers often respond
to a higher frequency, and CD and DVD players typically respond to a lower frequency. Making the correct choice about which IR output to use
depends on how well the audio source equipment responds to remote control commands.
Using the Output Section
The OUTPUT section of the 2430 amplifier is designed to control an external amplifier. This is necessary to provide enough power for multiple
pairs of speakers in a single area or zone. The OUTPUT section is for use with zone 1 and works with the zone 1 keypad for volume.
The “Control” output is a voltage trigger used to turn an external amplifier on and off when the zone 1 keypad is turned on and off. This connection
is made with a single mono cable with a mini (3.5 mm) jack on each end. Any amplifier you wish to control with the 2430 System requires a
voltage trigger input.
The “Audio” output is a stereo mini (3.5 mm) jack and is used to provide an audio signal to the external amplifier. Most audio amplifiers have a
stereo RCA-type input for the audio signal. This input has labeled “Left” and “Right” channels and is color coded with red and white. The
necessary stereo mini connection to RCA cable is readily available at any electronics retailer.
