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.

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.
Please also note that when the Advanced Settings menu is activated, it is not possible to switch a sound source using the source selector switch (12), change the volume using the volume control (11) or switch off the unit. To do this, first exit the Advanced Settings menu using the menu key marked EXIT.
3.1 Global settings
The following settings are available for each input group, no matter if digital, analog, stream, CD, .
3.1.1 Balance
With the Balance function you can shift the right-left balance in the range of 9.5 dB to the left or to the right to compensate for imbalances.
3.1.2 Set Tone Control
The menu item Tone Control activates the tone control of the device, which allows to adjust the bass and treble. This allows the adjustment of bass and treble components in the sound image as well as a loudness setting. In the LINEAR position, the tone control is deactivated and by-passed (settings made are still saved). In position TONE ON, the tone control is ready for operation and is activated, as soon as you make a setting under Bass, Treble or Loudness. Provided that a neutral setting (BASS = 0, TREBLE =
0, Loudness = 0), the tone control remains by-passed in the ACTIVE position until one of these parameters is changed. If no neutral setting is made, the active tone control is shown in the upper part of the display.
Bass and treble can be boosted or cut together for all inputs (GLOBAL) or specifically for the currently selected input (INDIVIDUAL). If an individual setting is desired, the inputs must be parameterized beforehand via the setup (see section 3.8.5). This is useful, for example, to compensate for a bass weakness of the turntable without having the boosting the bass of other input sources. The setting of the loudness function (Loudness) depends on the loudspeaker and room and is therefore globally valid for all inputs.
NOTE: As soon as the tone control under Tone Control is set to LINEAR, the menu items Bass, Treble and Loudness are not displayed.
3.1.3 Bass
The Bass menu item can be used to adjust the low frequency response from -7 to +7 dB. With a global setting for all sound sources, GLOBAL is displayed in the upper right corner of the display. individual setting INDIVIDUAL.
3.1.4 Treble
The Treble menu item can be used to adjust the high frequency reproduction from -7 to +7 dB. With a global setting for all sound sources, GLOBAL is displayed in the upper right corner of the display, INDIVIDUAL for individual settings.
3.1.5 Loudness
Listening to soft music often gives the impression of a flat, unbrilliant sound. This is due to a characteristic of the human ear: Bass and treble are perceived disproportional with quiet sounds. This effect is supposed to be corrected by the “aurally correct volume setting” (loudness) this effect by boosting bass and treble when playing soft music, and then gradually returning to a linear frequency response as the volume is increased. For this compensation to achieve its full effect, careful adjustment is necessary. Therefore, proceed as follows:
Select a sound source and set a moderate listening volume. Then switch to the Loudness menu. Now select menu keys (4) and (5) one of altogether 9 available Loudness values, until the sound image appears balanced and pleasant to you. As soon as you exit the menu again (menu key APPLY), the selected setting remains stored.
NOTE: When the Loudness menu is called up again, the displayed value may differ from the originally selected setting. This is not an error, but is caused by the fact that the sound control selects an adjustedvalue depending on the currently set volume. The current value is then displayed accordingly when you select the Loudness menu.
3.2 Analogue inputs
For the analog inputs, only the settings from the Global Settings are available.
3.3 Digital Inputs (COAX, OPTO, ARC)
After selecting a digital input, a further setting option is displayed in the menu.
3.3.1 Filter
By pressing the menu key (6) you can access the digital filter setting. Here you can choose between available digital filter settings for the selected digital input. You can select the digital filter settings STEEP and SMOOTH according to your sound preferences. Depending on the signal being played back, different digital filter settings can produce optimal sound results. Technically, STEEP means steep filtering at the end of the band end with flat amplitude frequency response, but strong phase rotation. SMOOTH, on the other hand, is less steep and already has a small amplitude drop before the end of the band, but less phase rotation. The selected filter setting applies only to the current input and remains stored – even after the unit is switched off.
3.4 Streaming input, CD player and USB
If you select the CD player or the USB input, you also have separate setting options.

3.7.2.2 Volume Limit On Activate
Sets the volume level to which the unit will be limited when switching inputs, if exceeded.
3.7.2.3 Volume Limit
This menu item allows you to limit the maximum output volume up to 50%. This function can be useful to avoid rapid volume jumps that are triggered, for example, by accidentally operating the volume control in the RC X app for iOS and Android incorrectly. The default setting is 70% and is intended as a protective mechanism to prevent other components in your system (e.g. speakers) and, last but not least, your ears from drastic volume jumps that could be triggered, for example, by accidentally operating the volume control of the RC X app for iOS and Android.
3.7.2.4 Source Gain
In a surround system, the leveling of all channels as well as the bass management is done at a corresponding surround decoder (e.g. by an AV receiver). This signal should not be changed, otherwise the balance of the channels among each other is no longer given.
The CS 2.3 offers a so-called source-fix function for this case. This allows you to operate the analogue inputs RCA 1 and RCA 2 with a fixed gain. If the source-fix-function is activated, the signal is played back with a fixed gain when this input is selected. In addition, all sound settings (e.g. BASS, TREBLE, see 3.1) are deactivated – regardless of whether you change the volume of the other inputs or their sound setting or balance setting.
The source-fix function is also available for the digital inputs COAX (26) and OPTO (27). In contrast to the analogue inputs, however, the sound settings (e.g. BASS, TREBLE) and the balance setting are active here. This function is useful, for example, if a sound source with its own volume control is connected to a corresponding digital input. (e.g. Sonos).
3.7.2.5 Input Gain
Often the connected sources in a HiFi system have different volume levels by nature. When switching sources, a jump in volume occurs. This can be minimized by individually adjusting the input sensitivity of the inputs to achieve similar volume levels on all sources.
Select a local digital or analogue input (26, 27, 31 32) with the source selector switch (12) and set the listening volume to a comfortable level with the volume control (14). Check whether the levels are approximately identical by switching to other inputs. If you notice a deviation, you can adjust it using this function. Select the desired level with the menu buttons (4) and (5) to select the INPUT Gain menu and the corresponding source. Using the menu buttons to adjust the level of the selected sound source within a range of -9.5 and +9.5 dB. Press the APPLY menu button to exit the menu. The set input level is now saved and the unit switches to the general operating mode.
By switching back and forth between the individual sources with the source selector (12) you can compare the set levels and adjust the sensitivity of all analogue and digital inputs – including CD and USB – accordingly.
NOTE: Please note that all remote controls are inoperative during level adjustment. While you are making menu settings on the main unit, the optional RC 9/10 remote control cannot be used to avoid operating conflicts.
3.7.3 Inputs
Personal settings regarding the inputs can be made here.
3.7.3.1 Skip Unused Inputs
If you do not need all analogue and digital inputs, the unused inputs can be deactivated (SKIPPED). When selecting sources with the rotary switch (2), all inputs defined as SKIPPED are automatically skipped and are also not selectable via the UP/DOWN function of the remote control. The settings can be undone at any time by calling up the menu item again (Input ACTIVE).
Skipping unused inputs makes it easier for you to operate them via the source selection key (12) and the UP/DOWN function of the remote control. Skipped inputs can still be selected via the RC 9/10 remote control or the RC X app.
NOTE: The settings described in the following section can be made easily and conveniently via the RC X App for iOS and Android. (See section 3.9)

Supplement

4.1 Taking care of the housing
The surface and frontpanel printing of the housing are largely scratch- resistant. The CS can be cleaned with mild soapy water or a glass cleaner and a soft dust cloth.
ATTENTION: When cleaning, liquid must never be allowed to enter the inside of the enclosure. In addition, for safety reasons, the mains cable should be disconnected before wiping with a damp cloth. Do not use solvents or abrasive cleaners that could damage the surface or printing of the enclosure.
4.2 Failure search (or: If something does not work as expected….)
Often alleged defects can be traced back to operating errors, sometimes other components connected to the unit are also responsible for a malfunction. Before contacting your dealer or us about a malfunction, please check the following list to see if you can correct the malfunction yourself..
1- No music playback
a) The MUTE function is active. Deactivate it.
b) Accidental switching to stand-by mode via the remote control. Press the switch-on button.
c) If the display is dark and the stand-by LED (1) is not lit, the mains fuse may be defective. Since this is usually caused by a defect in the power supply unit or the amplifier electronics (e.g. as a result of a lightning strike), please contact your specialist dealer.
2- Remote control is not working:
a) The battery of the remote control is empty. Please recharge the remote control / replace the battery.
b) There is no direct connection between the remote control and the unit, or the distance is too large.
c) A CD is inserted, „no disc“ in the display.
Either a dirty or defective CD has been inserted or the CD has been inserted the wrong way (label side down instead of up). Eject the inserted CD and insert it correctly. Clean the dirty CD and insert it again.
3- Lipsync is not synchronous for the digital inputs.
If, despite supported low-latency technology, the lip synchronization is not correct, your TV often offers its own setting option to compensate for this. Your CS 2.3 does not currently have its own setting for this.
4- HDMI ARC without function

If the HDMI ARC function does not work right away, please note the following points:
– Was the HDMI INPUT with ARC label used to connect the CS 2.3 to the TV?
– Is the HDMI cable ARC-capable?
– Has HDMI ARC been selected as the output source? (Sometimes a “connection” must be set up manually here).
– Have all settings been made on the TV, which may prioritize in the sound settings (That e.g. OptoOUT is prioritized)?
– Has PCM been selected as the sound format?
If it still does not work, the display information on the CS2.3 can help to find an error:
– No Signal -ARC Error: There is no signal from the TV: please check input and settings again.
– No PCM: Please change the audio format on the TV to PCM.
NOTE: Please note that device control can also occur if you have selected a “normal” HDMI input on the TV to connect the CS 2.3 and not the HDMI ARC INPUT.
