Applications

The receiver CS-W4C provides four channels and, combined with the wireless microphones CS-W4T, creates a wireless conference system. If the conference system requires more than four microphones, multiple receivers CS-W4C can be interconnected by means of the cables provided.
The REMOSET function is a most convenient feature for operating the system: It allows you to make settings for the microphones on the receiver and then transfer these settings to the microphones via a radio signal.
The receiver uses “Diversity” technology: The signals sent from the wireless microphones are received by two antennas to ensure a more reliable radio transmission. The signal of the highest quality is then used. The transmission range depends on local conditions; in open-field conditions, the maximum range is 100 m.
An automatic mixing function ensures that only a single microphone is switched on at a time; this will minimize the problems involved when multiple microphones are simultaneously used (e. g. comb filter effects, tendency to feedback and poor speech intelligibility caused by back-ground noise). A priority option for any channels allows the chairperson, for example, to take the floor at any time.
In addition, a control voltage is provided for each channel which allows you, for example, to create a channel status indicator.

Setting up the Product

The receiver is designed for installation into a rack (482 mm/ 19”); however, it can also be placed on a table. For installation into a rack, 1 RS (rack space = 44.45 mm) is required.

Connections on CS-W4C

Always switch off the receiver before making or changing any connections.

1. Insert the two antennas provided (2) into the antenna jacks ANT.A and ANT.B (16) and put them in a vertical position.
   Hints:

2. To increase the range and the interference resistance, the antenna amplifiers UB-900I can be inserted. The amplifiers are supplied with power via the antenna jacks of the receiver (chapter 4.4).

3. By means of the antenna cable set RTF-UF20, the antennas can also be fixed to the front of the receiver: Insert the jacks of the antenna cables through the mounting holes (1) and fasten them; then connect the cables to the antenna jacks (16).

4. Two options are available for routing the microphone signals received to the audio inputs of the subsequent unit (e. g. mixer, amplifier):

   • For routing all signals individually: Use the XLR connections CH1– CH4 (21).
   • For routing all signals mixed: Use the connections MIXED AF OUTPUT (20).
   • The output levels can be switched between line level and microphone level (chapters 4.4 and 4.6.1).

5. For power supply, use the cable provided to connect the mains jack (14) to a socket (230 V/ 50 Hz).
   Hint: The receiver has a low power consumption even when it is switched off. Therefore disconnect the mains plug from the socket when the receiver is not used for a longer period of time.

Interconnecting Multiple Receivers
Fig. 4 shows interconnection of multiple receivers CS-W4C. Two antennas and a mains cable are only required for the first receiver. The other receivers are interconnected by means of the cables provided. Thus, up to ten receivers CS- W4C can most conveniently be interconnected. When more than 22 channels are operated simultaneously, however, it is recommended to use receivers with different radio frequency ranges (e. g. …/5 and …/6) to prevent interference. The antennas (2) are matched to the frequency range of the respective receiver; there-fore connect the outputs “cascade” (17) only to receivers of the same frequency range to ensure optimum reception.

Switching outputs
For each receiver section, the LED indicators AF (11) indicate the status “on” or “off” (chapter 1.1). To control an additional status indicator, for example, depending on the status, the terminal strip VOLTAGE OUTPUT (18) provides a control voltage for each channel. The control voltage is +5 V when the channel is activated and 0 V for the status “off” (at the terminal with the number of the receiver section, related to the common terminal GND). The following example figures show how the control voltage can be used to control an LED indicator (fig. 5) or a 12 V relay (to switch larger loads, fig. 6).

Fig. 6 Example with relay

 Connections on CS-W4T

Gooseneck microphone
Connect the gooseneck microphone provided to the mini XLR jack (23) of CS-W4T; then tighten the nut to secure the microphone.
Place the foam windshield provided onto the microphone cartridge to suppress pop noise and to protect the microphone from the moisture from your breath.

Power supply
Two non-rechargeable batteries or two recharge-able NiMH batteries (AA) supply CS-W4T with power. To insert the batteries, open the battery compartment on the lower side of the unit and insert the batteries as indicated in the compartment. Then close the compartment.

NiMH batteries can be recharged when they are inserted in CS-W4T. Two chargers are avail-able:
W4-CH1: Charger for a single microphone W4-CH12: Transport case with charging function for up to 12 microphones

REMOSET Function
Transferring settings to the transmitters The settings of the transmission frequencies (or groups or channels) made on the receiver and other settings can be most conveniently transferred to the corresponding transmitter by a press on a button. The settings transferred to the transmitter depend on the configuration of the REMOSET function in the menu (chapter 4.6.3).
Always make sure that

1. no menu is called up on the receiver or on the transmitter.
2.  the transmitter is switched on and close to the receiver (REMOSET transfer range: ap-prox.10 m).
3. the REMOSET function is not locked or disabled on the transmitter.
4. the transmitter and the corresponding receiver section are set to the same identification number.
5. the batteries of the transmitter are not discharged.

Identification Number
Each pair of transmitter / receiver must have a different identification number (ID no.); this is the only way to make sure that each transmitter is supplied with the settings intended. The receiver sections 1– 4 are preset to the identification numbers 1– 4. Resetting will also reset the receiver sections to these numbers. When further receivers CS-W4C are used, they must be assigned different identification numbers (e. g. the second receiver must be assigned the numbers 5 – 8):

1. Keep the button SETUP pressed to call up the menu. Turn the knob PUSH/CONTROL to select the receiver section to be changed (CH 1– 4). Press the knob and then select item 5. Remo set ID in the submenu (fig. 7 in chapter 4.3.)

Turn the knob PUSH /CONTROL to select the setting; then press the button SETUP to save the setting.

Squelch
The interference suppression will mute the receiver section in speech pauses when interfering signals are received and the levels of these signals are below an adjustable threshold value. A high threshold value, however, will reduce the transmission range as the receiver will also be muted when the power of the radio signal from the transmitter falls below the threshold value adjusted. Therefore, adjust a high threshold value when the reception is good and a low value when there is a great distance between the transmitter and the receiver.

1. Call up the setting for interference suppression via the menu item 4.Squelch:

2. Turn the knob PUSH/CONTROL to change the threshold value:
   0 = standard setting
   1 … +10 the higher the threshold value, the lower the sensitivity to interference signals
   –1 … –5 the lower the threshold value, the higher the sensitivity to interference signals

4. Press the knob SETUP to save the settings made or exit the submenu by means of the button EXIT or via the line Return.

When the option Yes is selected for Bypass, the automatic mixing function will be deactivated and it will not be possible to make any further setting in this menu. In this case, Open means for all receiver sections Rx1…4 that all microphones can be simultaneously used for speaking. The LED indicators AF (11) of all receiver sections will light up permanently in this operating mode as soon as a radio signal of the transmitter is being received.
When the automatic mixing function is activated (Bypass No), the following setting options will be available:

Threshold
Threshold value for the audio signal level of the microphone (minimum volume while speaking) to switch on a microphone channel [the LED indicator AF (11) of the receiver section will light up]

Delay Time
Time the microphone channel will remain activated after speaking or in speech pauses

Priority No/ Yes
When a channel without priority (Priority No) is used for speaking, the signals of the other channels without priority will automatically be suppressed (i.e. attenuated by approx. 30 dB). These channels will only available for speaking when the previous speaker has finished speak-ing or makes a speech pause of sufficient length (Delay Time).

Speakers using channels with priority (Priority Yes) will be able to interrupt speakers using channels without priority provided that the volume of speech of the speaker interrupting other speakers exceeds the volume set as the Threshold value. When multiple channels have been set to Priority Yes, these channels can be simultaneously used for speaking.

appears on the left side of the display. To de-activate the key lock, keep the button pressed for 2 seconds until the symbol disappears.

Wireless Microphone CS-W4T

To switch on the wireless microphone CS-W4T, move the sliding switch (22) on the rear side to the position ON or LOCK. The power LED indicator (24) will light up in green. When the switch is moved to the position LOCK, the display (25)will briefly show Loc on . In this position, the microphone can be used for speaking; however, it is not possible to change the settings of the micro- phone. When the sliding switch is moved back to the position ON, the display will briefly show and Loc on will then show the frequency set or the group / channel.
Press the button (29) to speak. The LED indicator (26) will light up in red. After speaking, press the button again; the LED indicator will extinguish.

Note: Whether the person speaking can be heard via the receiver when the LED indicator (26) lights up in red, also depends on the priority settings on the receiver (chapter 4.7).
To save the batteries, use the switch (22) to switch off the microphone (position OFF) after usage and possibly during longer speech pauses.
