Wireless Radio Connections 

The Indigo features both a Bluetooth A2DP receiver and also a custom digital RF link for the Chord modified 
iPod. Both systems are independent of each other and can be used at the same time without interference. The 
provided antennas should be attached to the rear before using either system.  
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Bluetooth Receiver 

Advanced Audio Distribution Profile or A2DP for short allows Bluetooth devices to transfer high quality music 
wirelessly. Any phone, PDA or computer that supports A2DP can connect to the Indigo and play music without 
wires.  
There is a simple pairing procedure and with a 30m range it can be used anywhere in the home. 
We have provided a Bluetooth adapter for use with the iPod. This device simply plugs into the bottom of the iPod 
and connects automatically to the Indigo to transfer your music. 

 
Chord Digital RF Link 

The Chord modified iPod comes with its own RF wireless adapter allowing the digital audio signal to be 
transferred without docking the iPod. Connect the adapter to the bottom of the iPod and the connection will 
automatically be made. 

Please note that due to the complexity of the link the RF adapter is a class 1 device with a maximum range 
of 10 meters. 

Screw both antennas to the sockets on the rear of 
Indigo as shown. Pointing one vertically and one 
horizontally gives the best performance. (The 
antennas are identical so can be fitted to either 
socket)
