1. APart MA200CDR Mixing Amplifier
The MA200CDR is a professional 4 zone PA mixing amplifier for commercial and industrial applications.
Rarely seen on its competitors, all microphone inputs have integrated speech filters and they are high-class transistor-balanced type, allowing good control of hum and noise over long cables.
He’s able to drive 8-ohm or constant-voltage loudspeaker lines (50-70-100V).
The amplifier has integrated radio, 4 microphone inputs, 4 selectable line sources and one emergency/telephone input.
Mic input 1 is meant to be the main microphone paging input, for its signal can be fed via the front ¼” TRS phone jack or via a combo XLR3/jack, DIN 5 or euroblock connector at the back.
The MA200CDR has a three level priority system.
The emergency/telephone input at the back has the highest priority. Its signal goes directly to the main amplifier, bypassing any front control, and an attenuator next to the input sets its level. Microphone input 1 has the second priority level. With the control next to the XLR input, the vox (voice activated) mute for microphone 1 can be activated and mutes all other signals, except the emergency input. The third level can be activated via a dry contact (“priority over music”) and mutes all background music inputs only. This contact activates the chime as well, only when a level has been set using the “chime level” potentiometer.
4 Zones can be individually switched on and off.
Compared to other zone amplifiers, the total load (200W) can be drawn in any combination from the
4 zones.
Zone 4 has an extra feature. Via the selectors at the front, you can choose whether this zone receives back ground music only, messages only, both or none of them.
When any priority has been activated, 24V DC output (max.1A) will be available to activate priority relays of loudspeaker attenuators or other devices.
When needed, the signals distributed via your MA200CDR mixing amplifier, can be recorded via the record output.
19” Brackets are shipped along with your amplifier.
The MA200CDR is the all in one device to built larger professional industrial sound applications.
You can insert an extra equalizer (such as the APart PXQ2215) into the signal path or add extra power amps (APart PA240P), using the pre amp out/power amp in RCA connectors. When shipped a RCA bridge has been inserted.
The MA200CDR complies with the CE standards.

1) Power switch: Here you can switch the power on and off.
2) Overload indicator: This red LED illuminates when one of the protections have been activated. No or distorted sound will be heard anymore. This will be in case of overheating, being the result of drawing too much power from your amplifier, or the impedance of the speaker lines connected are below the minimum load impedance (see17).
3) Level indicators/clip-limit: A green LED will light after powering on. To work within normal conditions the volume indicator should be kept under 0dB (100%). At -2,5dB a limiter will be activated. This red LED indicates that the “auto gain circuit” keeps the level below clipping. This is NOT a clip indicator, but an indication of the “automatic gain control”.
4) Zone selectors: With these selectors you can activate the zone outputs. A green led at the left of the switches will confirm that you have activated zone 1 to 3. For zone 4, two selectors are available. By means of those two selectors you can decide to send background music only, spoken messages only, both or none of them. Two yellow leds will confirm your selection. When you have selected the music only mode for zone
4, there will be silence during paging.
5) Master level control. Here you can adjust the desired volume of the overall signal.
6) Microphone 1 input: This balanced ¼” TRS phone jack has been wired in parallel with the other three input options for microphone 1 at the back. For satisfying operation, use only one of these inputs at the time for microphone 1. Microphone 1 can be given a priority over all other inputs by using the VOX priority (see 29).
7) Microphone 1 level control: Adjusts the volume of the microphone connected to one of the four input connectors (1/4” jack, XLR3 combo jack, DIN5 or euro block).
8) Microphone 2 3 level control: By turning each control clockwise the desired level of that input in the total mix is set. To decrease these levels, turn counter-clockwise. The volumes of the inputs not in use, should be set fully counter-clockwise. If not, hiss might occur.
9) Microphone 4 / line 4 level control: Adjusts the input signal of the microphone connected to the XLR combo jack at the back or the line source connected to stereo RCA input 4.
10) “Muted by priority” led: This red led will blink when any priority status has been activated.
11) Music level control: Here you can adjust the level of the line source selected.
12) Line source selector: Select the desired music source to be heard (AUX, CD or TUNER).
13) Bass control: Adjust as per your taste. In reverberant rooms intelligibility can be increased by decreasing bass. The centre position gives you a flat response.
14) Treble control: Adjust the level as per your taste or needs. Adding high frequencies gives brilliance to your sound. High frequency feedback can be removed by decreasing treble. The centre position gives you a flat response.

15) Voltage selector. Set the local voltage: If any doubt, contact your dealer. The unit is shipped with the selector set to 230VAC.
16) Mains socket: The unit can be connected to the mains circuit by a standard IEC type power cord. This socket contains a 6,3AT, slow blow fuse. Use a screw driver to flip out the fuse compartment and to replace it by the same type. When this fuse blows frequently, you should check the speaker load or bring the MA200R to a qualified service centre. First check whether you didn’t use a quick-blow fuse!
17) Zone 100V loudspeaker outputs: When you need to activate/deactivate separate loudspeaker zones, you should use these 100V outputs. These connectors should only be used for 100V operation. They are activated by the selectors at the front (see 4). Don’t use these 100V outputs together with the 8 ohm, 50V or 70V terminals. The minimum impedance of all 100V loudspeaker lines together should be at least 50Ω
(100Vx100V/50Ω = 200watt).
18) Emergency power supply: You can power the amplifier directly from an emergency battery or power supply supplying 24V DC/20A.
19) Loudspeaker outputs: For low impedance use com and 8Ω. Keep impedance above 8Ω.
For 50, 70 or 100V speaker lines use COM and 50, 70 or 100V terminals.
For 100V operation, the total minimum impedance of the loudspeaker lines should be 50 Ω. For 70V operation the minimum impedance should be 24,5 Ω and for 50V 12,5 Ω.
Don’t mix the types of speaker connections. Only one at the time should be used, unless you are able to calculate a combination which does not overload the amplifier (example: 100Ω at 100V for a loud zone in combination with 25Ω at 50V for a quiet zone).
20) 24V DC output: At this terminal (-/+) 24V DC will be available (max. 1A) from the moment a priority has been activated, to control priority relays of local volume attenuators or other devices.
21) Power amp in / pre amp out: You can send the signal of the pre-amplifier to an external device such as an equalizer (APart PXQ2215) or limiter and feed the treated signal back into the amplifier via the power amp input. From the “pre-amplifier out” you can also feed extra power amplifiers such as the Apart PA240P. Don’t forget to feed the signal back into the “power amp in”. When you don’t use this feature, the RCA bridge should be placed.
22) Tuner output mono: Here you can recover a fixed signal of the internal tuner to feed other devices such as your telephone’s ‘music on hold’ system.
23) Rec. out: When you need a copy of the total mix, you can connect this output to any recording device such as tape deck, MD recorder, VHS recorder, etc….You can also use this output to feed an extra amplifier. This output level cannot be controlled separately. When you connect your MA200R pre amp out or record out to a microphone input of another mixing amplifier, this input will have signal overload and the sound will be masked. In this case you should use a line input, a DI-box or other signal levelling device. Never connect this output to an amplifier loudspeaker output!
WWW.APART-AUDIO.COM
24) CD stereo input, 500mV: Here you can feed a line level signal. You have to make your choice with the selector at the front (see 12). Stereo signals will be summed together.
25) AUX input, 500mV: Use this stereo RCA input to connect a line level source such as CD player, MD player,
BGM computer, etc…. You have to make your choice with the selector at the front (see 12). Stereo signals will be summed together.
26) Line 4, 200mV / Mic 4 input: Use only one of these parallel wired inputs at the time! To the XLR3 balanced input you can connect any microphone using a balanced, two wire shielded cable. (1=earth / 2 =hot /
3=cold). For using condenser microphones see 41. The Microphone 4 input is a XLR3/combo jack, which will accept a normal XLR3 male plug or a ¼” TRS phone jack.
Line 4 is more sensitive than the other line (music) inputs, therefore ideal to connect wireless microphone receivers.
27) Mic 2 Mic 3 XLR inputs: To the XLR balanced input you can connect any microphone using a balanced, two wire shielded, cable (1=earth / 2 =hot / 3=cold).
28) Mic 1 XLR / DIN5 / Euro block: Use only one of these parallel wired balanced inputs at the time! See wiring diagram at the back. These three inputs have been wired in parallel with the balanced jack input at the front. When you use the APart MICPAT or MICPACB paging microphones, connected directly to the DIN5 input, the signals fed into the line inputs are muted automatically while paging. The same kind of connection can be made using the euro block connector. To use “vox mute” see 29.
Phantom power: use condenser microphones see 41
29) Vox mutes all: When you activate “vox mute” by turning this trimmer clockwise to the desired threshold level, the signal of any Mic1 input has priority. When you don’t need “vox mute”, turn this trimmer fully counter-clockwise to the “OFF” position.
30) Priority over music contact: By closing the contact of the euro block connector or contacts 4 and 5 of the
DIN5 connector, the signal of microphone 1 only has priority over the music sources (TUNER, CD and
AUX). All other microphones will remain active. The contact closure of the contacts mentioned can give priority to the other microphone inputs as well. At the same time 24 V DC will be available at terminal 20.
This is very useful when using up to 4 microphones in supermarkets, etc…
31) Chime level: When one of the priority contacts are closed a chime can be activated by turning this trimmer clockwise to the desired chime level. When you don’t need a chime, turn this control fully counter-clockwise to the “OFF” position.
32) Emergency / telephone input: Here you can feed the audio source for paging emergency messages, etc..
This input, at line level, has automatic activation above 200mV and has a line transformer to avoid ground loops (useful for telephone). Please use a balanced, shielded line cable. Connect the HOT signal to +, the COLD to and the shield to G (when connecting the shield only at the MA200R side, you might avoid a ground loop, which creates hum and buzz). This signal is directly fed into the main amplifier.
No microphones should be connected directly to this input without using a mic to line pre-amplifier.
33) Emergency / telephone level: With this potentiometer you can set the desired level of the line level signal inserted into the priority signal input 32. This level will not be influenced by the “master” level.
34) FM antenna: This socket has to be used to connect your 75 ohm FM antenna. You can use the shipped indoor “wire” antenna, but to improve the reception, we advise to install an outdoor FM antenna or to connect the MA200R to the cable radio network.
Important notice: In case you connect to the cable radio network, we recommend a ground isolator HF transformer in order to avoid hum (ground loops) or wire only connecting the HOT pin.
35) AM antenna socket: Here, the shipped indoor AM antenna has to be connected.
36) Airflow output: This airflow output should be kept free at all times! To give the fan a longer life time, he only starts running when the heatsink reaches a certain temperature.
4. Tuner Controls
RADIO
AM / FM mode switch: Each time you press this button, the tuner will switch from FM to AM and the other way round. The actual radio band will be displayed at the left.
Scan up / down: By pressing “UP” or “DOWN” a few seconds, the tuner will start to search the next/previous radio station with sufficient signal (auto scanning). By just pressing “UP” or “DOWN” you work in manual mode. Each time you press, you change the frequency by 50 kHz for FM and 9 kHz for AM.
Memory scan: By pressing this button the tuner will start to scan across the memory presets. Each preset will be heard for about three seconds, starting from the next preset, till you reach the preset you where listening to again.
To stop this feature, press “SCAN” again.
Memory set: After you have found a radio station you like, you can save it in a memory. Press “MEMORY SET” and
“MEMORY” will appear at the upper right corner. Then select one of the 10 memory locations at the bottom of the front panel. You don’t have to reconfirm. The code of the memory will appear in bigger characters at the right of the display. The first memory locations can be selected directly. To select memory 6-0, first press shift followed by 1, 2,
3, 4 or 5. A total of 10 locations are available for FM mode and 10 for AM mode.
CD & MP3 PLAYER
CD power on / off: Press once and your CD player will be switched on. “SCAN” appears followed by “OPEN” and
“NO disc”, when no CD has been inserted. When you don’t use the CD player, we advise to switch it off.
CD slot: Insert a CD gently and “CLOSE” will appear followed by the number of tracks on the CD. Don’t push anymore when you feel that your CD player accepts the CD inserted. The first track will automatically start to play and the time elapsed will be displayed at the right. At the left of the display the kind of CD and the Play Mode will be displayed (audio CD or MP3). By default the CD player starts in “loop” mode.
When you insert a MP3 CD, the player starts to count the number of tracks of each folder. To the right of “MP3” appears the folder number and the counter starts running till the last track has been counted. Afterwards the first track of the first folder will start to play.
Next / previous track: Use these buttons to jump during playback to the following or previous tracks.
Play / pause: When you press once, the music stops and the “pause” indicator appears. At the right the time elapsed will be displayed flashing. After you have pressed this button again, the music will continue to play.
Stop / eject: To stop the CD player during playback, press once. The number of tracks will be displayed; for MP3’s the number of folders too. When you press for the second time, the CD will be ejected and “OPEN” appears. Take out the CD. When you don’t remove the CD, he will be inserted and start to play again.
Play mode: At any time the way of playing can be changed. Initially the CD (MP3) will start to play in continuous mode. The following play modes will be available: Continuous “( )”, random “RANDOM”, play 1 track repeatedly “¹” and play the CD once till the end “►”.
Folder select: When you have grouped music tracks into folders (for MP3 only), you can scroll through these folders by activating “FOLDER”. Now scroll by pressing the buttons “next/previous”. To deactivate, press “FOLDER” again.
Program set: At any time you can switch to program mode. Press “PROGRAM” and this mode will be confirmed at the upper right corner of the display. Select the track(s) you want to listen to by selecting them with

Phantom on / off jumper
The MA200CDR has been shipped with these jumpers in the OFF position. For each microphone input a jumper is available. When you put a jumper to the ON position, phantom power will be supplied to the microphone input involved so you can use condenser microphones. In this case NO unbalanced jacks should be used! Phantom power does not damage dynamic balanced microphones.
Power supply fuse (inside the housing)
When this fuse blows, replace it by the same type: 20A quick blow. When this happens frequently, contact your nearest dealer.
Now you are ready to build your solid sound system and our extra features will be of great help.
Note: In our policy of continuous improvement, changes can appear without prior notice, including the user manual.
Troubleshooting
No power: Check whether the “on/off” switch is in the on position and whether the power cord has been inserted properly. If these two have been checked and still the MA200CDR remains off, the fuse might be blown.
No sound: Check all the wires and loudspeaker selectors.
At least the master and one source should be turned clockwise.
Check whether the pre amp out is connected to the power amp in.
In the worst case your MA200CDR is in protective mode.
Please check your loudspeaker wiring and loads.
Operate your MA200CDR within normal conditions.
Distorted sound: Your input signal is too high.
Haven’t you a line level source connected to a microphone input?
You might also be drawing too much power from your MA200CDR and the loudspeaker load might be too low (minimum 50 Ohm for 100V use).
Check the speaker wiring and load with an impedance tester. Turn down the master level.
Hum and buzz: Please check your wiring and grounding, maybe you created a ground loop.
See that all equipment linked are drawing power from the same power supply.
Your radio might get its signal from the cable radio. In this case you have created a ground loop and a ground loop isolator between the cable signal and your radio antenna input will be the solution.

7. How To Deal With 100V Loudspeaker Systems
In fact working with 100V loudspeakers is rather simple, when done in the right way. Each 100V loudspeaker has a 100V transformer which can be set to a certain power, for example: 1,5 3 or 6W. As the example shows, the sum of all loudspeaker settings should never exceed the amplifier’s power specifications. Never use low impedance (= 8 ohm) loudspeakers on a 100Volt system, even not one.
More technically: When your paging amp has a maximum output of 200 watts at 100V, this means that the minimum impedance connected should be at least 50 ohm (100x100/200). To check your loudspeaker lines use a decent impedance checker (example AP WM100).
Now you are ready to get the best result on distributing your music and messages to your audience.
Your little giant is like a Swiss knife which will astonish you and many others!
