APPLICATION INFORMATION
1. Power Supply
The power supply inputs are designed to run off of a variety of batteries. The level must remain above
4.0V at the rated currents or unstable operation will result. Suggested battery types:
•
3.8V – 4.2V in one LiIon cell
•
4.8V – 7.2V in 4 – 6 NiCd or NiMH cells
•
4V – 9V in 4 – 6 Alkaline cells (0.8 – 1.0V end-of-life cell voltage assumption)
2. Audio Inputs
The module is designed for three different types of audio inputs.
•
Headphone-level audio from personal audio players
•
Line-level audio from standard audio components
•
Balanced audio from microphones (pre-amplified) or musical/PA equipment
The module has two sets of inputs on its main connector. These can be solder-jumper-configured for
headphone and line level (default), or headphone and balanced. The quick-connect port can host only
one type of input or one type of output, selected by solder jumpers. Headphone, line, and balanced
inputs are available on the quick-connect port.
On the main connector, the IN_SEL line selects between the two sets of inputs on that connector.

3. Audio Outputs
Like the inputs, the module is designed for three different types of audio outputs.
•
Headphone-level audio to earbuds or standard headphones
•
Line-level audio to standard audio components
•
Balanced audio to musical/PA equipment
The module has two sets of outputs on its main connector. These can be solder-jumper-configured for
headphone and line level (default), or headphone and balanced. The quick-connect port can host only
one type of input or one type of output, selected by solder jumpers. Headphone, line, and balanced
outputs are available at the quick-connect port.

4. I2C Communication
The module acts as an I2C slave to support extended functionality when embedded in a product that has
microprocessor control. The module maps a number of different registers accessible through the I2C
communication. These registers allow setting of parameters that include but go beyond the functions
available directly on the pins. Current settings and immediate status may be read back through the
registers.
Please contact Aerielle for further information.
5. Tx/Rx Selection
The Tx/Rx selection pin (TX_RX) is available only on the transceiver version of the module. This pin
selects whether the module plays the role of transmitter or receiver. With no connection, the pin is
pulled high internally and the unit functions as a receiver. When this pin is pulled to ground, the module
functions as a transmitter.
On dedicated transmitter or receiver versions of the module, this pin has no function.

6. Channel Selection
The module supports 8 “consumer” channels and 8 “professional” channels, intended for use in musical
instruments and other professional audio applications. The division of channel types is primarily to
prevent interference with professional audio applications by users of consumer-class devices (wireless
headphones, music-sharing platforms) at a public venue.
The CHSEL line controls the selection of the class of channels. This line is pulled up internally, and by
default (high) selects the consumer class of channels. Strap this line to ground (low) to select the
professional class of channels.
The CHSEQ line allows simple sequential selection of channels. A very simple product could use this line
to select channels by stepping through them (albeit blindly) with a single pushbutton. This type of
channel selection is very similar to cordless phones. When you encounter interference on one channel,
you push the button once to step to the next channel. When you have a pair of devices (one transmitter,
one receiver) and you change the channel on one to avoid interference, you would simply sequence the
channel button on the other device until you hear the audio link re-established. (This requires that you

know what the audio source is playing so you can identify it on the receiver.) This line is pulled up
internally, and the channel advances each time it transitions to ground. The input is debounced internally
to allow the use of a simple electromechanical pushbutton switch.
The CH0, CH1, and CH2 lines provide for direct selection of the channel. Use these lines to select the
channel from a microcontroller or when you want to hard-wire a particular channel other than the
default. These lines are pulled up internally so they must be pulled down to select. See the following
table that shows active-low binary selection. In this way, Channel 0 (all lines high) is the default.

7. Volume Control/Mute
On the transceiver or dedicated receiver version of the module, there are simple function pins for volume
control and mute. These control the output volume in the headphone-drive mode.
•
VOLUP
Transition to ground increases volume at headphone outputs by one step.
•
VOLDN
Transition to ground decreases volume at headphone outputs by one step.
•
MUTE
Ground mutes headphone output and floating or high-level input un-mutes it.
