Class 1 Bluetooth transmission has a range up to ten
times that of Class 2 devices. Class 1 operation can
typically be 150 feet (45.7 meters) in ideal conditions
with mobile devices. Actual range of Bluetooth Class 1
technology may be aected by physical obstacles as well
as the performance of devices with which the MB20 is
intended to connect, particularly Class 2 devices. Think
of this measure as a point of comparison since the world
is not always ideal. As a receiver, the maximum range is
determined by the capabilities of both paired devices.
Internal sampling and bit shifting, which can be thought
of as sophisticated up-sampling, will enable all digital
processing to occur and the highest available speed and
resolution. The MB20’s internal DAC processing at 192
kHz is the gentlest way of ltering the audio signal. The
digital output will be at 96 kHz for wider compatibility
with other DACs.
Bluetooth Transmit and Receive support aptX HD for
improved sound quality. Plus aptX
TM
Low Latency audio
improves end-to-end speed of audio transmission to keep
the sound in sync with the screen. Using two MB20, one
as a receiver and the other as a transmitter, provides full
wireless aptX HD code and decode bridge.

Receiver or Transmier
The MB20 can be either a Receiver (RX) or Transmitter
(TX). It can switch between these two modes, but it can
only be one of these at a time.
Set the MB20 to the desired mode, either RX or TX, by
pushing the RX/TX Button located on the rear of the
unit. See Figure 1. When the RX/TX Button is depressed
(pushed in), the MB20 is in Receive Mode. When the
