Additional audio con- nections on the controller CS-1CU make it easy to integrate other devices (such as recorders, amplifiers, wireless microphone systems, equal- izers, telecommunications). Each microphone station (CS-1DU and CS-1CH) is equipped with a high-quality microphone capsule, a speaker and two head- phone jacks with volume control. The micro- phone stations for chairpersons (CS-1CH) have a priority button, allowing the chairperson to interrupt the discussions of other delegates for their own messages. Various discussion modes (e. g. a defined number of delegates talking at the same time or a talking time with automatic limit), an indi- cation of date and time, a separate stopwatch feature, a key lock feature for the controller and a test feature for all microphone stations connected make the system extremely versatile. If more than 50 microphone stations are required, the CS-1EXM and CS-1EXS devices, available as accessories, can be used to combine two or three conference systems to create a system that may contain up to 150 microphone stations. 4 Connections Always switch off the devices before making or changing any connections!

4.1 Microphone stations

For connecting the microphone stations, the two jacks “Trunk in /out” (19) are provided on the controller. Each of these two jacks can be used to connect a chain of up to 25 microphone stations of type CS-1CH and /or CS-1DU.

1) Connect the plug (29) of the first microphone

station to one of the jacks “Trunk in /out” (19).

2) Connect the plug (29) of the second micro-

phone station to the jack (28) on the rear of the first microphone station (or to the other jack “Trunk in /out” on the controller).

3) Proceed in the same way to connect further

microphone stations. CS-1CH and CS-1DU17 English devices can be connected in any order. The number of microphone stations connected to the two jacks on the controller may also be different.

4.2 Additional microphone

It will be possible to connect an additional microphone or the receiver of a wireless microphone via the jack “Microphone” (20). For microphones requiring phantom power, a voltage of 12 V is present at this jack. Therefore, do not connect any microphones or wireless receivers with unbalanced output signal to this jack; they may be damaged.

To record a discussion, connect the input of a recorder to the RCA jacks “Recorder out” (15). The signal level at these jacks is independent of the speaker volume adjusted. To reproduce a recording, connect the out- put of the recorder to the RCA jacks “Recorder in”. These jacks are provided both for the left (L) channel and the right (R) channel of a stereo recorder; however, signal processing in the con- ference system is monophonic.

4.4 Signal source with line level

A mono signal source with line level (e. g. output of a mixer) can be connected to the RCA jack “Line in” (16). If only a stereo signal source is available and the input “Recorder in” is not used, the signal source can be connected to this input.

To reproduce the discussion via an amplifier system, connect the input of the amplifier or mixer to the jack “Line out” (16).

4.6 Telephone coupler

To include a person in the discussion over the phone, a telephone coupler can be connected to the jacks “Telephone” (13). This telephone coupler will provide the necessary electrical con- nection between the telephone network and the conference system. Caution: Never try to directly connect a telephone line to the conference system!

4.7 Inserting external signal processing

To insert an additional device for signal process- ing (e. g. an equalizer for adjusting the sound or a compressor for limiting the dynamic range) into the signal path of the conference system, connect the input of the device to the jack “Insertion out” (14) and its output to the jack “Insertion in”. To activate external sound processing, set the switch (12) to position “I”.

As an alternative to listening via speakers, head- phones can be used. For this purpose, the con- troller is provided with a jack (2), the microphone stations are equipped with a jack (24) both on the left and on the right. When a plug has been connected to a jack, the corresponding speaker will be switched off.

Finally connect the mains cable provided to the IEC connector (10) first, then connect it to a mains socket. 5 Operation Note: If no device for external sound processing is connected to the jacks “Insertion” (14) or if a device connected to these jacks is not used, set the switch (12) to position “O”. Set the volume control (4) to “1” first, then switch on the controller with the POWER switch (9). The display (5) will show the last operating mode selected and also the date (format: year – month – day) and the time (format: hour : minute : second). To set the clock

5.1 Selecting the operating mode

1) Keep the button SET (8) pressed for approx.

2 seconds. Instead of the date, will keep flashing while the setup menu is open.

2) Use the buttons (6) or (7) to select one of

the following operating modes: “Over Ride Mode” To switch on the microphone of a delegate, briefly press the talk button (27). The LED(23) on this microphone station and the ring (22)18 EnglishEnglish of this microphone will light up while the microphone is on. To switch it off, press the button again. As soon as another delegate switches on their microphone, the microphone of the delegate speaking at that moment will be switched off automatically. The microphone of a chairperson using a microphone station CS-1CH will not be switched off. It can be switched on /off inde- pendently of the other microphone stations. “Chairman Only” Only a chairperson using a microphone station CS-1CH will be able to switch on or off their microphone via the talk button (27); the microphones of the delegates will remain switched off. “Open Mode” A defined number of delegates will be able to talk at the same time. If the maximum number of microphones is switched on, it will not be possible to add another microphone. A delegate requesting to speak will have to wait until one of the delegates has switched off their microphone. This restriction does not apply to a chair- person using a microphone station CS-1CH. Chairpersons can use the talk button (27) to switch on or off their microphone at any time. “Timer Mode” This operating mode is similar to “Open Mode”, but in “Timer Mode”, a microphone will be automatically switched off after being on for 30 seconds. This will prevent delegates from permanently blocking the discussion of other delegates if, for example, they forget to switch off their microphones.

3) For “Open Mode” and “Timer Mode” only:

Press the button SET: the icon will flash. Use the button or to adjust the maximum number of delegates talking at the same time (1– 4).

4) Press the button SET to confirm.

The display will briefly show “Saving” and the setup menu will disappear.

5.2 Operation of the microphone

To switch on the microphone, briefly press the talk button (27). The LED (23) and the ring (22) will light up as soon as the micro- phone has been switched on. Note: If switching on is not possible, it may be prevented by the controller (

chapter 5.1) or via the priority button of the microphone station for the chairperson (

2) When headphones are connected to one of

the jacks (24), the speaker (25) of the micro- phone station will be switched off. Depend- ing on the maximum volume adjusted on the controller, the headphone volume can be adjusted for both jacks together with the control (30) on the right of the microphone station. CAUTION Never adjust the headphones to a very high volume. Perma- nent high volumes may dam- age your hearing!

3) To switch off the microphone, press the talk

button (27) once again. The LED (23) and the light ring (22) will go out. Note: The microphone can be switched off at any time by the controller (

chapter 5.1) or via the priority button of the microphone station for the chairperson (

5.2.1 Adjusting the microphone

sensitivity Each microphone station has a control GAIN (31) on its lower side. Use a small screwdriver to adjust the gain and thus adapt the sensitivity of the microphone to the person speaking.

5.3 Microphone stations for

chairpersons CS-1CH Switching on and off the microphone via the talk button and adjusting the headphone volume and microphone sensitivity of the microphone stations for chairpersons CS-1CH is the same as for the microphone stations for the other delegates (

chapter 5.2). However, the chair-

person can switch the microphone on at any time and only the chairperson can switch it off again.19 EnglishEnglish

5.3.1 Priority button

The priority button allows the chairperson to interrupt a discussion between delegates. As long as the priority button (26) is kept pressed, the microphones of all delegate stations will remain switched off. The adjustment of the two switches on the lower side of the micro- phone station for the chairperson will define the behaviour when the priority button is pressed or released: left switch (32) upper position: when the priority button is pressed, a signal will sound lower position: when the priority button is pressed, no signal will sound right switch (33) upper position: when the priority button is re leased, the microphones of all delegate stations will remain switched off lower position: all microphones of dele- gate stations which were on before the priority but- ton was pressed, will be automatically switched on again when the button is released

5.4 Volume adjustments on the

Use the control (4) to adjust the volume of all speakers and the maximum volume of all headphone connections on the controller and on all microphones stations connected. In case of feedback noise, e. g. when the microphone stations are too close together and the micro- phone sensitivity on the microphone stations is set to a very high level (

back the control accordingly. The control offers 11 positions, in position “0”, all speakers and headphones will be switched off. The signal level at the output “Recorder out” (15) will not be affected by this control.

5.4.2 Speaker and headphones on the

controller Use the control (3) to adjust the volume for the headphone jack (2) and the speaker (1). When headphones are connected to the jack, the speaker will be switched off. CAUTION Never adjust the headphones to a very high volume. Permanent high volumes may damage your hearing!

5.4.3 Volume for external microphone

If required, match the volume for a micro- phone connected to the jack “Microphone” (20) or for a receiver of a wireless microphone: Use a small screwdriver to turn up the control “ Gain” (18) only to such an extent that the sound reproduced is not distorted.

5.4.4 Volume for the input “Recorder in”

If required, match the volume for a signal source connected to the jacks “Recorder in” (15): Use a small screwdriver to turn up the control “ Gain” (17) only to such an extent that the sound reproduced is not distorted.

To do this, the microphone stations are connected by means of the extension devices CS-1EXM and CS-1EXS as shown in figure 4. In this case, one CS-1CU controller is used as the main device (master) and will control the entire system. However, the other CS-1CU controllers (slaves) are required to supply power to the additional microphone stations. To connect the devices, cables of type D7PDM-1 and extension cables D7P-..., available in various lengths, are required.21 English Combining 3 conference systems ➃ REAR TO: CS-1 EXMTO: CS-1 CH/DUFRONTTO: CS-1CU (Slave) CS-1EXS CS-1 EXS REAR TO: CS-1 CH/DU TO: CS-1 EXSFRONTTO: CS-1CU (Master)CS-1 EXM CS-1EXM CS-1CU (Master) CS-1CU (Slave) REAR TO: CS-1 EXMTO: CS-1 CH/DUFRONTTO: CS-1CU (Slave) CS-1EXS CS-1 EXS CS-1CU (Slave) CS-1CH/DU ≤ 25 ≤ 25 CS-1CH/DU ≤ 25 ≤ 25 CS-1CH/DU ≤ 25 ≤ 25 D7PDM-1 D7P-1/D7P-3/D7P-5/D7P-10/D7P-2022 EnglishEnglish 7 Specifications
