3 Applications

The lectern SPEECH-204 consists of a high-quality 2-way speaker system, a mixing amplifier with four input channels and a receiver module for two wireless microphones. It is ideally suited to reproduce sound, e. g. for lectures, speeches, readings etc. The optional wireless microphones offer additional mobility (e. g. for passing round the microphones in the audience when questions arise).

In addition to three microphones, it will also be possible to connect other audio units (e.g. CD player for adding music). Via the jacks LINE OUT, REC, the output signal will be routed to a recorder or to another amplifier system. The integrated reading light offers two brightness levels.

The two integrated castors on the rear of the lectern allow convenient transport.

3.1 Wireless microphones and transmitters

The following units are available from MONACOR:

Type	Model
Hand-held wireless microphone	TXA-800HT
Pocket transmitter with tie clip microphone and head-band microphone	TXA-800HSE
Transmitter with line level input for audio signals	TXA-800ST

3.2 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare that the wireless receiver of the lectern SPEECH-204 complies with the directive 2014/53/EU. The EU declaration of conformity is available on the Internet:

www.monacor.com

The wireless system (transmitter and receiver) is generally approved for operation in EU and EFTA countries, it is licence-free and requires no registration.

4 Transport and Setting up

For transporting the lectern, seize the top part and tilt it slightly backwards so that it will stand on its two castors only. Thus, it will be easy to wheel it to the place of application. Set up the lectern is such a way that the speakers on its front will be directed towards the audience.

5 Connections

Prior to connecting any units or to changing any existing connections, switch off the amplifier system and all units to be connected.

5.1 Microphones and audio unit

1) Connect a microphone (e. g. a suitable gooseneck microphone from the EMG...P series) to one of the XLR jacks (1 or 4) on the upper side of the lectern and adjust it to the person speaking. It will also be possible to equip both jacks with one microphone each. The jacks have a latching; to disconnect the plug, press the PUSH lever.

As an alternative, connect a microphone with XLR plug to the input jack (7) of the channels 1 and 2 on the rear of the lectern. Like the jacks on the upper side of the lectern, these microphone inputs will supply the phantom power (24 V) required by some microphones.

The input jack of channel 3 allows connection of another microphone with XLR plug.

2) To connect a signal source with line level (e. g. mixer, CD player), use the 6.3 mm jacks (7) of the input channels 1–3 (if the corresponding channel is not used by a microphone) or the RCA jacks AUDIO IN (9) of channel 4. When both RCA jacks are connected (e. g. stereo signal from a CD player), the signals will create the sum (mono).

Note: If you use any wireless microphones, their signals will be mixed to the input signal of channel 1.

5.2 Recorder or additional amplifier system

The RCA jacks of the output LINE OUT, REC (10) allow connection of a recorder or another audio unit with line input (e.g. an additional amplifier system for PA applications in large zones). The mixed signal of the audio sources will be available at these jacks.

5.3 Power supply

Connect the power supply cable provided to the mains jack (14) and connect the mains plug to a socket (230 V/50 Hz).

6 Operation

1) Before switching on, set the VOLUME controls (5) of all four input channels to "0" to prevent switching noise and an excessive volume.
2) Switch on the audio sources connected first, then switch on SPEECH-204 with the POWER switch (13). The POWER LED (12) will light up. If an additional amplifier system for PA applications has been connected to SPEECH-204, switch on this amplifier system last.

After operation, switch off the units in reverse order:

1. the additional amplifier system
2. SPEECH-204
3. the audio sources connected

3) Mix the signals of the input channels with the corresponding VOLUME controls (5) or fade them in and out as required. When using wireless microphones, also see chapter 6.1. Only adjust the volume to such a level that the sound reproduced will not be distorted.

If the LED LIMITER (11) lights up frequently, the input level is too high and should be reduced with the corresponding volume control.

Make sure to use an adequate volume level. Permanent high volumes may damage your hearing.

To prevent feedback howl, never direct the microphone towards the speaker and never place it too close to the speaker. Feedback may also occur when the volume is too high. In this case, reduce the microphone volume with the corresponding VOLUME control (5).

4) To optimize the sound for the channels 1–3, use the corresponding equalizer controls HIGH, MID and LOW (8). After modifying the sound, readjust the volume with the corresponding VOLUME control (5), if required.

6.1 Operation with wireless microphones

The lectern is equipped with a receiver module (17) for two wireless microphones / transmitters.

UHF-Duo 3 5 7 1 9 OFF CH.A 10 11 10 A B 3 5 7 1 9 SET OFF CH.B

② Wireless receiver module

Each receiver section (A and B) is equipped with a control to adjust the volume and to switch it on and off. The display is divided into two parts: left half for receiver section A, right half for receiver section B. When a receiver section has been switched on, the display will indicate the transmission channel. To briefly indicate the radio frequency, press the button (for section A) or (for section B).

6.1.1 Setting the transmission channels

Use the controls to switch on the receiver sections. Do not switch on the corresponding wireless microphones / transmitters for the time being.

6.1.1.1 Channel scan

Keep the buttons and simultaneously pressed for approx. 1 second until S n pears on the display. The scan will start: The receiver sections will be set to free channels without mutual interference. If no free channels are found, the channels set will be kept.

Note: The channel scan can also be started for one section only (button △ for section A or button ▽ for section B).

6.1.1.2 Manual channel selection

When both receiver sections A and B are switched on:

1) Keep the button SET pressed until the channel indication for receiver section A starts flashing on the display.
2) Select the channel for receiver section A with the button or and then confirm with the button SET.
3) The channel indication for receiver section B starts flashing on the display. Select the channel for receiver section B with the button or and then confirm with the button SET.

When only one receiver section A or B is switched on:

Keep the button SET pressed until the channel indication starts flashing on the display. Select the channel with the button or and then confirm with the button SET.

Notes:

1. The receiver sections cannot be set to the same channel.
2. If a channel is not confirmed within 10 seconds with the button SET, the setting mode will be exited and the channel previously set will be kept.
3. If, with the transmitter switched off, the respective segment bar A or B on the display indicates reception, interference signals or signals from other transmitters are being received. In this case, use a different channel.

6.1.2 Adjusting the volume

Switch the wireless microphones / transmitters on and set one to the channel of receiver section A and the other to the channel of receiver section B. The respective segment bars on the display will then indicate the strength of the radio signals received. Use the controls to adjust the desired volume for each receiver section.

Adjust the volume of the audio signals received with the VOLUME control (5) of input channel 1. If a microphone or another signal source has been connected to an input jack of the first channel (1 or 7), the signals will be mixed.

Notes

1. If you do not receive a signal from the wireless microphone, make sure that the microphone is transmitting on the correct frequency (channel) and check the battery of the microphone. Reduce

the distance between the lectern and the microphone, if required.

1. If reception is poor, turning or moving the lectern may improve it.

6.1.3 Setting the squelch

The squelch function will mute the respective receiver section when the level of the radio signal falls below the threshold value adjusted. Thus, interference signals will not cause noise when the transmitter is switched off or when its radio signal is poor: If the levels of the interference signals are below the threshold value, the receiver section will be muted. A high threshold value offers high interference resistance, but it will also reduce the transmission range.

1) Switch off the receiver sections A and B. Then keep the button SET pressed while switching on a receiver section. The display will indicate F or ,F with the number flashing.
2) Press the button SET to activate the squelch setting mode: S for "Squelch") and the current value (flashing) will appear on the display.
3) Use the button or to set the value (level 7 = highest threshold value). Press the button SET to exit the squelch setting mode.

Note: The setting modes will be automatically exited after 5 seconds if no button is pressed. Any settings made will be saved.

6.2 Reading light

To switch on the reading light (2), set the switch (3) to the position "I" or "II" according to the brightness level desired.
