General Information Connector and Cable Information
1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the MB50 Streaming Audio Player.
2. For the MB50 to receive streaming audio signals
from a mobile device, a wireless router with Wi-Fi
capabilities is required, in order to facilitate com-
munications between the MB50 and the mobile
device.
3. When connecting the MB50 to a wired Home
Computer Network (of which
includes a wireless router) a
USB (2.0) to Ethernet (RJ45)
Adapter such as a Monoprice
(109466) is required.
4. The MB50 internal Digital
Circuitry is designed for 2-channel PCM (Pulse
Code Modulation) Digital Audio Signals.
5. The MB50 is designed to be compatible with the
majority of Audio Power Amplifiers. However, do
to a wide range of Power Amplifier Designs, it is
important the input sensitivity of the amplifier be
at least 2 Volts. This will assure music recordings
are reproduced with adequate dynamic range. This
will assure the playback of most music recordings are reproduced with adequate dynamic range.
Check with your McIntosh Dealer for additional
information.
6. If it should become necessary to replace the supplied AC / DC Power Adapter, for use in North

How to Operate the MB50
Your McIntosh MB50 is factory configured for immediate enjoyment of superb audio from a Mobile Device
via Play-Fi or one of the external devices connected to
the Rear Panel of the MB50.
If you wish to make a Play-Fi wireless connection
between the Mobile Device and the MB50, please refer to “Introduction to Setting Up the MB50” on page
14 for additional information.
Power On
Press the ON/STANDBY Push-button on the Front
Panel of the MB50 or press the Power Push-button
on the Remote Control to switch On the MB50. Refer

Status
occurs approximately 2 hours after there has been an
absence of audible audio signals on the selected input
or user activity (includes changes to any of the Operation Functions such as Input selection, Volume adjust-
ment, etc). It also allows for choosing between if the
Network Connection (Sleep Mode) is maintained or
the Network Connection (Standby Mode) becomes ac-
tive thus terminating the Network Connection. If it is
desired to enable the Auto Off Feature perform either
of the following:
Auto Off with Network Sleep Mode Disabled:
1. Press and hold simultaneously the Wi-Fi/NET
and VOLUME ▼ (Down) Push-buttons until the
Front Panel Display Wi-Fi/NET LED Indicator
changes color from Green to Red. Then release the
two Push-buttons. The Power Save Mode is now
Disabled.
2. To Enable the Power Save Mode repeat step 1 and
the Wi-Fi/NET LED Indicator will change color
from Red to Green.
Auto Off with Network Standby Mode Enabled:
1. Press and hold simultaneously the STANDBY/
ON and VOLUME ▲ (Up) Push-buttons until the
Front Panel Display Wi-Fi/NET LED Indicator
changes color from Green to Red. Then release the
two Push-buttons. The Power Save Mode is now
Disabled.
2. To Enable the Power Save Mode repeat step 1 and
the Wi-Fi/NET LED Indicator will change color
from Red to Green.
Network Sleep Mode
The Network Sleep Mode is Enabled by default. With
the Sleep Mode active, the MB50 will automatically
switch On when the Mobile Device Play-Fi App
is started and the assigned name (for the MB50) is
selected. When the MB50 is connected to AC Power
for the first time (or if a Reset to Factory Default Settings is performed) its operational status is “Standby
Mode”. After switching AC Power first On to the
MB50 the Operation Status will automatically change
to the “Sleep Mode” when it is switched Off. To place
the MB50 in Standby Mode for just the current time
(Sleep Mode Disabled), perform the following step:
1. With the MB50 On, press and hold the STANDBY/
ON Push-buttons until the Front Panel STANDBY/
ON LED Indicator changes color from Green to
a flashing Red. Then release the STANDBY/ON
Push-button. When the MB50 has completed the

Play-Fi
For Mobile Device specific operating information
(Apple or Andriod) go to the Play-Fi web site at
https://play-f i.com/
Notes: 1. If you have questions about the Play-Fi App
and its Operation refer to the Play-Fi “Knowledge Base” for additional information.
2. Some of the Internet Music Streaming Services (available via the Play-Fi App) offer the
listener the ability to alter the sound quality
of music being streamed. Refer to each of the
Music Streaming Services Internet Web Site for
additonal information on how to make changes
to their default settings, if available.
Critical Listening Mode
The Play-Fi App supports the native sound resolution
formats of the music played. When the sound format is
high resolution, the sound is normally down-sampled
to insure proper Wi-Fi Streaming Capability with the
most common wireless network hardware. In the Play-
Fi App there is a Critical Listening Mode which keeps
the original sound resolution up to 96kHz/24Bit. This
requires the MB50 and Mobile Device be connected
by high performance network equipment. To activate
the Critical Listening Mode perform the following
17

steps using the Play-Fi App:
1. Select the “Hi RES Audio” Icon. Refer to
figure 32.
