What is aptX?
aptX is a high quality CODEC (CODer/DECoder) i.e. a way of compressing audio
data so it can be sent over a link such as Bluetooth then decompressed on the
other side (if both devices support it).
If your Bluetooth audio source does not support aptX, the BT100 will fall back to
using the standard SBC CODEC that is supported by all Bluetooth audio devices.

A. Pairing button/Status LED
Button performs pairing and related functionality. Integrated LED indicates BT100
status.
B. USB plug

C. Extension cable

Pairing
To begin streaming high quality music from your chosen media source it will first
need to be paired with the BT100.
A. Insert BT100 into the USB port at the back of your 851N.
B. Wait a moment for the BT100 to be detected. Then double click the button to
enter pairing mode, the BT100 indicates it is in the pairing state by flashing
rapidly.
C. Put your Bluetooth compliant audio source into pairing mode. Please consult
your manufacturer’s user manual on how to do this.
Pairing your BT100 and source establishes an authorised audio link that can then
be used again in the future without having to go through this stage again.
After pairing you can just select the BT100 and play at any time as long as your
Bluetooth A2DP compatible source (phone/laptop etc.) is within approx. 10m of
the BT100.
Normally on your source you will need to select Bluetooth Pairing and then the
BT100 should appear as ‘Cambridge Audio BT100’ in a list of locally found
Bluetooth devices.
Select that item in the list to finish pairing.
D. On successful pairing, the BT100s LED goes off for a second or two, then triple
flashes quickly. The LED then goes off and only lights up in the future when you
are playing audio via Bluetooth.
E. To play back via a paired Bluetooth device, simply select the BT100 on that
device and start playing. The BT100 LED lights up constantly when streaming
SBC or on and flicks off every 2 seconds when streaming aptX.
Notes:
– You can pair to more than one source up to a maximum of 8 sources at any
time. Pairing to a 9th device will cause the first one to be forgotten and so on.
However as you would expect the BT100 can only play back from one of these
sources at a time.
– When you have finished playback many sources keep the Bluetooth link active for
a time unless you actively tell them to stop by deselecting playback via the BT100
(do not unpair as this is not necessary).
This can prevent another source to be able to access the BT100.
To immediately use another source, simply deselect the BT100 for playback on
your first source device before starting up on a second.
– Some devices stream empty data all the time even when paused or stopped.
These devices will cause the BT100s LED to be on even if playback is currently
stopped or paused.
