2.3The Plena Mixer Amplifier

The Plena Mixer Amplifier is a high performance, professional public address unit for mixing up to four separate microphone/line signals, and any one of three separate music signals. For a schematic overview of the Plena Mixer Amplifier, see figure 2.1 on the next page.

The volume of each microphone/line signal can be individually adjusted to obtain the required mix; the mixed output is controlled via the master volume control and separate high/low tone controls.

The unit is easy to use, and provides a crisp call or clear music. The amplifier also has enhanced features such as ducking level control, priority, labelling, and setting indicators.

All Microphone/line inputs can be switched between microphone level and line level sensitivity. The inputs are balanced but can also be used unbalanced. Phantom power can be selected via a DIP switch to provide power to condenser microphones. Input channels 1 and 2 can take priority over all other microphone and music inputs:

Input 1 can be activated by contact closure on a PTT (push to talk). A chime can be configured to precede an announcement.

Input 2 can be switched automatically if a signal is available at the input, for example, if someone speaks into the microphone (VOX activation).

A telephone/100 V emergency input with VOX activation is also provided for easy integration with another PA system or a telephone paging system. It has its own volume control and overrides all other inputs, including the call station and inputs 1 and 2.

The unit also has a line output to add amplifiers for larger systems that require more output power. This output can be switched to music only, for example, so that music on hold can be provided for the telephone system.

Users can create custom labels for inputs and music sources. These labels can be attached to the special holders at the front of the mixer amplifier. Colored pins can also be inserted at various positions around the volume and tone dial controls to indicate favorite settings for a particular application.

4Connections and settings

4.1Connecting inputs

4.1.1Priority microphone (input 1)

The priority microphone (or a generic call station) that can be used with push to talk (PTT) should be connected to “microphone/line 1 input”. The PTT mode can be activated by setting the DIP switch (12) at the rear of the unit. Microphone/line 1 input has priority over all other microphone/line inputs.

If, however, the “Tel. emergency/100V input” receives a signal, all inputs including microphone/line 1 input will be overruled.

The microphone/line 1 input has two connectors wired in parallel:

an XLR connector (for a 3 pole microphone), and

a Euro style pluggable screw terminal connector.

The Euro style pluggable screw terminal connector has a trigger input, which can be used in combination with the Euro and XLR connector.

The priority microphone can be connected to the microphone/line 1 input as follows:

XLR connector only. See figure 4.1.

XLR connector with trigger. See figure 4.2.

Euro connector with trigger. See figure 4.3.

Euro connector only (without trigger).

Note

If a microphone is connected to both the XLR connector and the Euro connector for the microphone/line 1 input, the input signals will be added together.

Set the DIP switch settings next to the XLR connector for microphone/line 1, as required. See section 4.3.

Note

When connecting an unbalanced line level (200 mV) signal to the microphone/line input, connect it as follows: Signal to pin 2, pin 1 and pin 3 to ground.

Plena Mixer Amplifier | Installation and User Instructions | Connections and settings

en | 16

 

 

4.1.2Secondary microphone (input 2)

Connect a secondary microphone to “microphone/line input 2”. See figure 4.4.

Microphone/line input 2 has a DIP switch (12) at the rear of the unit for setting the VOX mode. If the DIP switch is set to VOX, the microphone/line input will automatically be switched when a signal is sensed at the microphone/line 2 input. For example, when someone speaks into the microphone, other sound will either be muted or ducked, depending on the setting of the ducking level control at the rear of the unit. See section 4.3.

The Tel. emergency/100V input and Microphone/line input 1 all have priority over the Microphone/line input 2. Therefore, any signal received on any one of these inputs will always be heard regardless of the ducking level control setting for Microphone/line input 2.

Set the DIP switch settings next to the XLR connector as required. See section 4.3.

4.1.3Additional microphones (inputs 3 and 4)

Connect additional microphones to microphone/line inputs 3 and 5 as required. See figure 4.4. These microphones will mix with the background music.

Set the DIP switch settings next to the XLR connector for microphone/lines 3 and 4, as required. See section 4.3.

4.1.4Emergency inputs

The Tel. emergency/100V input, with VOX functionality, is used for receiving emergency announcements or signals (such as a fire alarm). This input has absolute priority, and will overrule all inputs when an emergency announcement or signal is received.

Either a telephone line or a 100 V input signal can be connected to the Euro style pluggable screw terminal connector (1) at the rear of the unit. See section 4.1.4.1 and section 4.1.4.2.

Caution

Never connect telephone lines and a 100 V signal to the Euro style connector at the same time.

To adjust the volume of the emergency announcement or signal, turn the rotary dial (2) at the rear of the unit. For safety reasons, the volume of the emergency announcement or signal cannot be set to zero.

The master volume control setting (5) does not influence the volume setting of the emergency announcement or signal.

Note

Tel. emergency input does not mute the incoming signal so that an incoming pilot tone will be fed to the zone outputs. With this feature it is possible to use the mixer amplifier in a Bosch Voice Alarm System when using end of line boards (PLN-1EOL).

The signal that is delivered to the unit should be quiet when a call is not made. The pilot tone and frequencies below 300 Hz are filtered from the trigger signal so that the input will not trigger from a pilot tone or low frequency rumble.

4.1.4.1 Connecting 100 Volt input signal

Connect the 100 Volt input signal as shown in figure 4.5.

4.1.4.2Connecting telephone lines

Connect the telephone lines as shown in figure 4.6.

Caution

A connection to a telephone network must always be made via a telephone coupler that provides adequate isolation between the telephone network (PBX) and the Plena system. The telephone coupler must also meet all relevant requirements for this type of communication equipment as imposed by law and/or responsible telecommunication organizations in the country of use. Never try to make a direct connection between the telephone network and the mixer amplifier.

4.2Connecting outputs

4.2.1Main output

Connect speakers to the 100 V or 8 Ohm terminal on the Euro style pluggable screw terminal connector (17) at the rear of the unit.

Also see section 4.2.4 “Connecting speakers”.

4.2.2Call only

Connect speakers to the 100 V terminal on the Euro style pluggable screw terminal connector (17) at the rear of the unit.

Also see section 4.2.4 “Connecting speakers”.

4.2.3Master output

This output carries the master output of the mixer at line level (1 V balanced).

To hear music only set the internal jumper.

Use the music output connector (8) to provide a dedicated music out source for another device. For example, the music master output can be connected to a telephone coupler, so that callers can listen to music when they are put on hold (see figure 4.8).

To select the dedicated music out source, set the internal jumper. Only the music inputs (5, 6, and 7) will be audible. All other inputs, including the Tel. emergency/100V input will not be sent to this output.

4.2.4 Connecting speakers

4.2.4.2 Low impedance loudspeakers

 

4.2.4.1Constant voltage loudspeakers

figure 4.10: Connecting speakers

figure 4.9: Connecting speakers

The mixer amplifier can drive 100 V constant voltage loudspeakers.

Connect the loudspeakers in parallel and check the loudspeaker polarity for in-phase connection. The summed loudspeaker power should not exceed the rated amplifier output power.

You can use the Call Only output for 3-wire remote volume control override. You can also use this output as an extra zone where announcements can be heard, but not music.

Connect low impedance loudspeakers to the 8 Ohm/0 terminals. This output can deliver the rated output power into an 8 Ohm load. Connect multiple loudspeakers in a series/parallel-arrangement to make the combined impedance 8 Ohm or higher. Check the loudspeaker polarity for in-phase connection.

4.3.2Pin settings and labelling

Users can create custom labels for the: microphone/line inputs, description of the music sources, and audio output zones 1 and 2. These labels can be attached to the mixer amplifier at position numbers 2 and 3 (see figure 2.2). Colored pins can also be inserted at various positions around the dial controls to indicate the favorite settings for a particular application.

The pins are engineered in such a way that they cannot be taken out by hand. This is to prevent tampering. The pins are intended to be inserted once, during installation of the unit. The silver pins should be used to indicate the preferred settings of the unit. The red pins can optionally be used to indicate the maximum setting of a knob.

If these settings have to be changed, use a pair of softtipped pliers to carefully remove the pins. If you do not have a pair of soft-tipped pliers, you can use ordinary pliers instead, but first place some plastic tape on the tips of the pliers to prevent damaging the front of the unit.

To remove the clear plastic covers in front of the labels: 1 Carefully insert a small screwdriver into the cut-out

at the bottom of the plastic cover.

2Gently lift the cover, and bend it in the middle. Take care not to force the cover or the front panel.

To reattach the plastic covers with paper labels:

1 Insert the paper label into the holder at the front of the unit.

2Pick up the cover, and then bend it slightly in the middle by hand.

3Fit the cover into the slot at the front of the unit, and then gently release the cover, making sure that the paper label stays in place.

5.2Microphone/line controls

Note

Users can create custom labels for the microphone/line inputs and description of the music sources. These labels can be attached to the mixer amplifier at position numbers 2 and 3 (see figure 5.1). Colored pins can also be inserted at various positions around the dial controls to indicate the favorite settings for a particular application.

Use the volume controls (7) to individually control the sound level of microphone/line inputs 1 through 4.

5.3Music controls

5.3.1Source selection

Use the music source selector (8) to select one of the connected music sources.

5.3.2Volume control

Use the music source volume control (9) to control the sound level of the selected music source.

5.4Tone control

The tone controls are not standard bass and

treble controls: they can be used as a traditional tone control with high and low control, but also have a powerful contour that addresses problems found in real situations.

The tone control for the low frequencies boosts deep bass first without making the sound boomy, and cuts rumble without loosing warmth in the low frequencies.

Use the Hi (high) and Lo (low) tone controls (see figure 5.1, numbers 4 and 10) to change the tone.

5.5Output controls

5.5.1Master volume control

Use the master volume control dial (5) to collectively control the sound level of all outputs, except the emergency announcement/signal.
