Inputs and Outputs on the Back
Wired inputs are selected using the Left Knob. See Figure 6 on page 8.
Optical
The Optical input allows a digital source to be connected using a TOSLINK cable also known as an “optical audio cable.” The internal digital-to-analog converter (DAC) of the RS250 is able to process hires digital audio up to 192kHz/24-bit. The RS250 DAC will process standard format SPDIF PCM signals as well as Dolby Digital and DTS encoded multi-channel bit streams. Unsupported formats can result in strange and/or unpleasant sounds.
For HDMI and Optical volume boost adjustments see “HDMI and Optical Gain Adjustment” on page 12.
AUX
The AUX input accepts a 3.5mm
stereo male connector for analog Left
signals. This is also known as an Right
1/8 inch stereo mini plug, and is
Ground

headphones to phones or similar
Figure 3 3.5mm Plug for AUX Input
devices. This input can be used to
provide a wired connection to various music sources.
HDMI ARC (Connecting your TV)
The RS250 can receive audio via an HDMI cable from ARC enabled televisions.
Audio Return Channel (ARC) can provide two way communication between units
allowing for volume control and lip-syncing functions to ensure audio and
video are perfectly matched. This allows for more intelligent operation
between components as well as less cable clutter. Make sure this feature is
enabled in your TV’s setup menu.
The Lip Sync function is automatic with an ARC CEC connection. Lip Sync can be controlled with the RS250 remote control and will enable adjustments of audio to sync with accompanying video when CEC is defeated or with the optical input.
The HDMI ARC input is designed to be used exclusively with ARC compliant televisions. If the source is not ARC compliant, use the optical connection for digital sources.
For HDMI and Optical volume boost adjustments see “HDMI and Optical Gain Adjustment” on page 12.
PHONO
The PHONO input accepts RCA connections from a turntable to support vinyl record playback. The RS250 is configured to support Moving Magnet type phono cartridges. Use the ground lug to connect the turntable/tonearm ground wire.
Data Output
The Data Output uses a 3.5mm stereo male-to-male cable to send control signals to connected McIntosh source components. For instance, a PLAY command to a CD player can be sent using a single remote control.

Changing the Remote’s Battery
Someday, the AAA battery in the remote will need to be replaced. This is how
to do it. The back of the remote control is held in place by magnets. To
remove the back of the remote to reveal the battery, slide the front of the
remote up while sliding the back of the remote down. The goal is to move the
back 3/16 of an inch from the top of the remote and then lift it off. There
are many ways do to this, as far as positioning your fingers. To open the
remote:
· Hold the remote upsidedown and backwards withMcIntosh name upsidedown and
facing away from you. The thicker end will now be the top and you should be
staring at the back of the remote.
· Pinch the remote with your index finger resting on the Trim/Select button
and your thumb on the backside (facing you) opposite your index finger’s
position. Your thumb and remote should both be pointing away from you (see
Figure 8).
· Use your thumb to slide the back open 3/16 of an inch. Slide your thumb away
from you towards the thicker end of the remote, while your index finger goes
in the opposite direction (towards you). As if snapping your fingers in slow
motion. For added strength, you can use your other hand in a similar position
above your first hand using the same technique. Make sure you do not hold the
side edge with either hand.
· Lift the back off with your other hand before it snaps closed again. You can
grab the now exposed top edge.
· It gets easier after the first time. Remove and replace the battery noting
the polarity (printed below the battery if you forget). To replace the back:
Place the back in position 3/16 of an inch from the edge. The magnets will
help you snap it back into place.

Rear Connections
Ethernet Port
The Ethernet Port connects your RS250 to your network’s router using a
standard CAT5, CAT5E or CAT6 cable with an RJ45 connector. Using a wired
connection is one way to access the RS250’s setup via a browser. For more
information, see “The Browser Interface” on page 12.
AC Connector
Use the supplied AC Power Cord to connect the RS250 to a live AC outlet.
USB Service Port
The USB port is only for performing service functions by a qualified service
technician. It is not intended for USB device support or playback.

HDMI and Optical Gain Adjustment
Many video sources such as broadcast video to television sets have sound
levels that are lower than typical music sources. Because of this, a volume
boost has been added to the HDMI input making it louder. The ability to adjust
the volume boost of the Optical input has been added so that the Optical input
could be boosted as needed.
To adjust the volume boost:
· Go to HDMI or Optical input (whichever you wish to adjust).
· With a typical source playing, adjust the volume to a midpoint level.
· Rotate the knob located on the rear panel right side (when looking from the
front), and rotate to achieve the desired output level. Choose this level to
be approximately the same as what you would experience on another input. When
you have achieved the desired level, release the adjustment knob. This trim
level will be recalled for the HDMI or Optical input whenever selected. Note:
you may independently set the trim for HDMI and Optical input. One will not
affect the other.
These settings can be changed at any time.
The Browser Interface
To view the RS250’s browser interface, you will need its IP address.
There are several ways to find a device’s IP address. For instance, you can
use IP scanner software. Here is one way with out additional software. To find
the RS250’s IP address: With the RS250 connected to your network with a wired
or wireless connection:
· Type the IP address of your router into the address bar of a browser (often
192.168.1.1)
· Enter the router’s Username and password. (The default can be found in the
router’s documentation, but changing it is a good security rule)
· Look for the RS250 in the list of wired or wireless clients for your router
· Note the IP address With the RS250’s IP address:
· Type the address of the RS250 into the address
bar of your router
The RS250 Browser interface has three submenus: · OVERVIEW (see Figure 11) ·
SETTINGS (see Figure 12) · UPDATE (see Figure 13)
Click on the desired heading to enter that menu.
OVERVIEW Menu
The Overview menu provides the following information about the RS250:
· Serial Number · MAC Address · Network IP Address · Firmware versions
You can provide a Custom Name for the RS250. This is the name that will
display for available AirPlay devices. If you wish to change the default name,
type the new name in the box and press Enter. If the name was changed using
the Apple Home app, the name will not be able to be changed on the web page.
The Overview Menu provides an indicator for the status of your Wi-Fi (WIFI
enabled). When enabled the indicator will show ON and be green. An ethernet
connection takes precedence and will automatically disable Wi-Fi. Wi-Fi, if
set up, will reengage when the ethernet cable is disconnected.
SETTINGS Menu
The Power Sleep Timer has two settings:
· ON (default)
· OFF
When the Power Sleep Timer is set to ON, the RS250 will power off into a sleep
state after approximately 30 minutes of no sound or user input. After 60
minutes of uninterrupted sleep, the RS250 will enter a Standby Mode. In this
Standby Mode, the Wi-Fi radio is powered off and the unit can not be woken via
the network. Standby Mode power consumption is less than 0.5 watts.
If the Power Sleep Timer is set to OFF, the RS250 will power off into a sleep
state after 30 minutes of non-activity. The RS250 can be woken from sleep by
input from the network (or physically pushing the Power Button). In a sleep
state, the RS250 will continue to work with devices configured to control it
in your Google Home collection.
The RS250 can be made to immediately enter a sleep state by pressing and
holding the Right Knob for two seconds. If Power Sleep Timer is set to ON, the
RS250 will enter Standby Mode after 60 minutes of uninterrupted sleep.
The Startup Volume Limit has two settings:
· ON
· OFF (default)
When the Startup Volume Limit is ON, upon power loss or return to play from
Sleep or Standby, the first playback of the product will start at a low volume
level. When switched to OFF, the product will resume playback at the last
volume level.
The Settings Menu allows you to change settings for Wired and Wireless network
connections.

Select Network Type to see/change settings:
Figure 11 OVERVIEW Submenu
· Automatic
· Wired · Wireless
If Network Type is set to Automatic, the RS250 will
automatically connect to Wi-Fi when the ethernet
2
cable is unplugged provided the Wireless connection
2
has previously been setup. Selecting Wired for
Network Type will limit the RS250 network
connection to the ethernet port connection. Select
Wireless to setup a Wi-Fi network or to restrict the
network connection to Wi-Fi.
If you selected the Network Type of Wireless, the following submenus appear:
· Scan Networks
· Display SSID
· Network Password To set up a wireless connection for the RS250:
Figure 12 SETTINGS Submenu
· Select Start Scan
· In the Display SSID submenu, select a wireless network using the up/down
arrows
· Enter the Network Password for that Network · Select Connect
DHCP can be set to ON (Default) or OFF. If you change this setting to OFF, you
will need to provide the following information manually:
· IP
· Netmask
· Gateway · DNS (1st and 2nd)
With DHCP ON, this information is automatically acquired and the submenus to enter the information
are not visible.

Figure 13 UPDATE submenu
UPDATE Menu
The UPDATE menu allows you to reset settings to the factory defaults as well
as update your RS250.
To restore Factory settings, select the “Start Factory Reset” button. Done.
Note that you will lose your Wi-Fi and Bluetooth connection settings.
An alternative method for Factory Reset, is to Press and Hold the Left and
Right Knobs for 10 seconds.
Update Method allows you to set how the RS250 updates its firmware. When set
to the default of OTA Auto, the RS250 will periodically check for updates and
install them automatically. When set to OTA Manual, the RS250 will check for
available updates when you select the Start Search button to the right of
Check for Update. If an update is available, you
can install it by selecting Start Update. (OTA stands for “over-the-air”.)
The Service option for updating is for service purposes by a McIntosh
qualified technician only.
While the RS250 is in the process of updating the firmware, the power status
LED will blink twice in quick succession, pause for 2 seconds, and then repeat
during the entire process. Other internal processor updating will be
accompanied by other LEDs or indicator flashing. This is normal.
14
Re-packing the RS250
When shipping the RS250, it is highly recommended that the unit be packed as
it was originally shipped to avoid damage. Failure to properly pack the unit
will likely result in damage. If you need any of the packing material, you can
contact McIntosh Customer Service.
