1.11 RC Remote Control
The optionally available RC 9 or RC 10 remote control allows you to control your AVM device
conveniently and comprehensively. Before both components can be used together, they must first be
paired with each other. This one-time process is called pairing and sets up a wireless connection
between the RC 9 remote control and your device (see section 1.11.1). A detailed description of the
entire functional scope of the RC 9 or RC 10 remote control can be found in a separate operating
manual at www.avm.audio.
Important notice: A RC Dongle will be required to operate the RC 9 or RC 10, please contact your
specialist dealer for this.
1.11.1 Pairing
Pairing is the process of establishing a wireless connection between an RC 9 / 10 remote control and
your device.
There are two ways to start the pairing process:
1. You can start pairing via the RC X app from AVM. You can find the Start Pairing option in the
Settings under the RC 9/10 Remote Control item. Once you have started the pairing process via the
app, you need to start the pairing process in the RC 9/10 remote control shortly after using the
navigation buttons as well.

one of four hotkeys to the device (details on how to use the hotkeys can be found in a separate
RC 9/10 user manual on the AVM website at www.avm.audio.) By pressing the Enter button on the
RC 9/10 again, the pairing process is completed.
1.12 RC X App for iOS and Android
The RC X App for iOS and Android turns your smartphone or tablet into a handy remote control and
offers a variety of intuitive functions for using all streaming-capable models from AVM with integrated
AVM X-STREAM Engine®. The RC X app is available for free download from the Apple App Store and the
Google Play Store.
1.13 Network installation (LAN, WLAN)
To use the extensive streaming and network functions such as Spotify Connect®, Apple AirPlay2, TIDAL,
QOBUZ, HIGHRESAUDIO, web radio, podcasts or music-server, your device must be connected to your
home network or the Internet via a router. For this purpose, you can choose between a wired LAN
connection via the network connection (22) or a wireless WLAN connection (WiFi) via the supplied
WLAN antenna. When mounting the supplied WLAN antenna onto the corresponding WLAN antenna
connector (16), please make sure that the antenna is straight aligned.
LAN VS. WLAN:
If you have the choice between a wired LAN or wireless WLAN connection, we generally recommend
using a wired LAN connection, which usually allows a higher bandwidth and is also less susceptible to
interference and more independent of the data traffic of your entire network.
NOTE: All AVM devices with integrated AVM X-STREAM Engine® prefer a wired network connection
(LAN)) and will automatically access it as soon as a network cable is installed on the device and the
WLAN connection is automatically switched off. For a smooth continuous operation via a wireless
WLAN connection, remove any connected network cable (LAN) from the network connector (23).
Otherwise, the device will re-establish a wired network connection even during operation, as this is
preferred to the WIFI by the device.
Proceed as described below to start the installation of a wired or wireless network connection.
1.13.1 Setting up a wired network connection (LAN)

2.6 Bluetooth
The integrated Bluetooth function allows you to wirelessly transmit high-quality music signals from a
Bluetooth player such as a smartphone, tablet or PC to your AVM device. To activate and use the
Bluetooth function and use it, you must first pair a compatible Bluetooth player with your AVM device
(see the following section 2.6.1). Please also make sure that the Bluetooth antenna is attached to the
antenna connector (15).
NOTE: When screwing on the supplied antennas, make sure that they are aligned straight. Only after
screing the Atennas in firmly, angle the antennas to the desired position.
2.6.1 Pairing
To activate the Bluetooth input (BT), use the Bluetooth selection button on the front of the device (11),
the RC 9/10 remote control or the RC X app. By calling up the Bluetooth menu on the RC 9/10 remote

20
control or in the RC X App, you can connect and locate your CS 2.3 in the Bluetooth menu of your
playback device (player). In addition, you can manage the already paired devices in the Bluetooth menu
in the app.
To connect to the CS2.3, navigate to your player's Bluetooth menu, make sure the Bluetooth function is
enabled there, and start searching for available Bluetooth devices in your area. For details on how to use
the Bluetooth function of your player, refer to the corresponding user manual.
Once the AVM device appears in the drop-down menu of available Bluetooth devices on your Bluetooth
player (identified as AVM-x-xxxx*), select the AVM device as your audio playback device and wait for it to
be activated. When the pairing process is complete, the CONNECTED indicator appears in the lower left
area of the display and you can transfer music from your Bluetooth player to your AVM device.
NOTE: To avoid interference from the built-in Bluetooth antenna with other parts of your AVM device,
the Bluetooth module will be disabled once another source is selected. Should you switch back to
Bluetooth input, the AVM device will automatically connect to the last paired device if it is within range.
2.6.2 Pairing additional Bluetooth players
Your AVM device can only be paired with one Bluetooth player at a time. To switch to another Bluetooth
player, an existing connection must first be disconnected. This can be done in the RC X app for iOS and
Android under the Bluetooth item.
2.7 Choosing the appropriate termination for the phono input
With regard to an optimal playback quality, each pickup should be connected to the appropriate
termination impedance or termination capacitance. This is especially important for MC systems
We recommend that you take a look at the operating instructions for your pickup system before
adjusting the impedance. There, the optimal termination impedance is usually indicated. Otherwise, a
rule of thumb can be: For MC systems 100 Ohm terminating impedance.
The matching is done with the included RCA plugs. These must be plugged into the RCA input LOAD
(33) on the rear panel after selecting the correct value.
NOTE: Please make sure that you always plug the identical value into both inputs.
3 Advanced settings (MENU)
In addition to the basic functions, the CS has a wide range of options for individual adaptation to your
personal requirements. These functions are accessible via a menu, which can be operated using the
menu keys below the display. During the general operating state, the middle menu key is labeled MENU.
Pressing this menu key takes you to the 'Advanced settings' menu. The key label of the same menu key
now changes to EXIT. Press the key again to exit the 'Advanced settings' menu and return to the general
operating state. In the 'Extended settings' menu, the individual menu items can be selected with keys (4)
and (5) and selected with SELECT (8) - the selected item is shown in the display in each case. Use keys
(4) and (5) to change the value of the selected menu item. Confirm your selection with APPLY (8).
NOTE: Please note that in the Advanced Settings menu the available parameters depend on the
currently selected input.
