5 Installation It is very important to use a top quality RJ45 8/8 crimper tool. We strongly suggest using a cat 5 / RJ45 electronic tester to verify the wire conductors. Installing the MVP44a should be relatively easy. With a bit of planning, the MVP44a will give trouble free service for years. 1. The most important consideration when installing the MVP44a is cooling. The MVP44a has a lot of power packed into a small chassis size. When installing it in an equipment stack, it should be the top component. It needs at least 1-3/4" of space above the MVP44a to allow for adequate cooling. 2. When installing the MVP44a in a rack we suggest adding a 1-3/4" blank above and below the MVP44a. In multiple MVP44a installations, plan for a 3-1/2" blank (double) between each MVP44a and a 1-3/4" blank on the top and bottom. Amplifiers should always be the top components in a rack system. 3. If MVP44a channels frequently shut down due to overheating, either the output levels will have to go down or 8 ohm speakers installed. If 8 ohm speakers are installed on all channels and some channels still shut down, call the factory for advice. 4. Connect the MVP44a inputs to the source component outputs with good quality, short as possible RCA jack cables. Connect each channel individually. 5. If source D is not being used we suggest you short both of them out with a RCA shorting jack. This will make the room speakers quieter in standby modes. 6. Connect the MVP44a speaker outputs to speakers using good quality speaker wire. Minimum 16 gauge copper wire is recommended with 14 gauge minimum for runs over 30' (10m) Make sure the speakers in each room are connected in phase. Note: Ideally the MVP44a likes 6-8 ohm loads. Connecting to 4 ohm loads won't hurt the MVP44a but those channels connected to 4 ohm loads may occasionally shut down due to overloading. Never connect the MVP44a to 2 ohm loads. 6 7. Install MR60 keypads (or infrared receivers) in the rooms with the speakers. Cat 3 or cat 5 wire can be home run to the MVP44a or up to three rooms daisy chained on one wire. ***Be sure to set the dip switch on the rear of the MR60*** See the dip switch adjustment below. Connect all eight individual wires using RJ45 connectors. Four wire conductors are needed for each keypad (one unique, common: IR , ground and 12VDC). MR60 Dip Switch Adjustment Use either RJ45 connector as they are in parallel The rear of the MR60 is shown. Because one to three MR60's can be connected or daisy chained to the same cat 5 wire, the keypad position on the wire must be selected using the dip switch. The two MR60 RJ45 connectors are in parallel. Only one dip switch slider should be on and the other two off (#1 is shown on in this example). The MR60 1-2-3 dip switch positions correspond to MVP44a keypad ports and speaker outputs A3 or B1-B2-B3. ***Even if the keypads are home run, the MR60 dip switch position has to be selected*** If three keypads are daisy chained on one wire, select the MR60 dip switch on the first MR60 to one, the second MR60 to two and the third MR60 to three. At the rear of the MVP44a, the RJ45 connector from the three MR60 keypads can be connected any corresponding keypad Bank A3 or Bank B; port 1, 2 or 3. The corresponding speaker outputs will be the same number as selected on the MR60 keypad (example: the MR60 keypad with #2 dip on and connected to MVP44a keypad bank B will control speaker outputs B2R and B2L). After installation, if the keypads are not working properly or not controlling at all, Check the MR60 dip switch settings, wiring layout and crimp as well as bank connections very carefully.
