Weight: 22 lbs (10 kg)

Operating Temp: -20C to +60C (-4F to +140F)

Caution: Never listen to sound that is distorted. If distorted sound

is heard, turn the volume down immediately or speaker

and/or amplifier damage could occur that is not covered by the

warranty. If this problem persists, contact your dealer.

Complies with part 15 of the FCC rules. Operation is subject to:

1. This device may not cause harmful interference

2. This device must accept any interference received

including interference that may cause undesired operation.

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.

Congratulations and thank you for choosing the Knöll MVP44a power amplifier. The MVP44a is designed to meet the amplifier needs of custom installed multi-zone systems where high quality sound is a specific requirement as well as ease of installation and operation. A six output zone model is available, MVP64a. Troubleshooting Key Features: 1. Individual zone, four source selection. Each of the four rooms Problem Action Power indicator does not light - no sound 1. Check that the MVP44a is plugged in. 2.

possible in the sequence to give the components settling time. For example, sequence a power-on command: CD on, tuner on, and CD play rather than CD on, CD play, and tuner ON. 7. Make sure the PROGRAM lamp is on. 8. Make sure the bank 1 switch is on and bank 2, 3 and 4 are off. 9. Push the SEQ (sequence) button. 10. Carefully touch (for one sec.) the wire to the bank 1 + terminal 1 to 6 where the first sequence is to be stored. 11. Move the bank 1 switch off and the bank 2 switch on. 12.

...System layout considerations continued In certain commercial applications a microphone paging override is required. Model MR171 paging and override module takes a balanced or unbalanced mic, (with defeatable phantom power) or a line level input and when activated overrides all inputs (even if some or all zones are in standby) and pages at a preset volume in all zones. A variety of door chime and telephone paging, door entry and front door camera modules are being developed.

gather all the source remotes (with batteries inserted) near the 59000. Screw one end of a temporary wire to the 590-00 terminal marked +12VDC. Power up the 590-00 and the MVP44a. The 590-00 can learn up to 16 different commands on each of its four banks. If more than 10 different IR commands are being stored use bank 2, 3, and 4 to store the sequence commands and bank one positions 1-6 to execute the sequences. Single IR Command Storing Start by pushing the RES (reset) button on the back of the 590-00.

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).

MVP44a to Xantech 590-00 The Xantech 590-00 is an infrared learning "remote" capable of converting a dry contact closure of each of the MVP44a's four functions, power-on (TON) and power-off (TOFF) to an IR macro sequence of up to 10 commands each. The 590-00 power supply is shipped with the 590-00. Power to the 590-00 should be on all the time (like a TV set) so the system IR commands can be sent as soon as any MR60 source buttons are pressed.

MVP44a Rear Panel Note 1: Ideal speaker impedance is 6-8 ohms. When using 4 ohm speakers, individual channels may occasionally shutdown due to protection system.
