3.3  
The 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 one music signal.  
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 priority, labeling, 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 channel 1 can  
take priority over all other microphone and music input:  
Input 1 can be activated by contact closure on a PTT (push to talk). A chime can be  
configured to precede an announcement.  
Users can create a custom label for inputs and music sources. The label can be attached to  
the special holder 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.  
An LED meter monitors the master output before the zone selection. This signal is also  
present on the headphone connector below the output meter. For total reliability and ease of  
use, a limiter is integrated into the output stage to restrict output if the user applies too much  
signal.

Planning  
Calculate your total power needs based on the sum of the power handling capacity and  
tapping of all loudspeakers planned in your system. When you use the volume controls,  
assume the maximal setting for this calculation.  
Make sure that the unit has sufficient air around it for ventilation. For units with a fan, make  
sure that the cabinet where the unit is placed in can evict air from the rear. For units without  
a fan, leave room on top of the unit for convection. Units with a fan do not need free space  
directly above the housing. Take at least 10 cm into account for connectors and wiring. Make  
sure that no liquids can spill into or on the unit and that the air intake holes are not  
obstructed. Make sure that there is a power outlet of sufficient rating close to the intended  
location.

7.1.2  
Pin settings and labeling  
Users can create custom labels for the: microphone/line inputs, description of the music  
source. These labels can be attached to the mixer amplifier at position number 2 (see  
Figure 3.1). 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 soft-tipped 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.  
2. Gently 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.  
2. Pick up the cover, and then bend it slightly in the middle by hand.  
3. Fit 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.

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 8.1, numbers 3 and 7) to change the  
tone.

Maintenance  
The mixer amplifier has been designed to function without problems for a long time with a  
minimum of maintenance.  
In order to guarantee trouble-free operation, clean the unit with a damp lint free cloth,  
especially the air intake holes on the front. Have a technician clean the dust from the fan and  
the inside at regular intervals for the models that have a fan. Base the interval on the actual  
situation and dust build up, start with an interval of at least once per year. Periodically check  
the connectors for corrosion and check the screw terminals to make sure that they have not  
become loosened.
