NetStreams Musica Power Amplifier Introduction The MU290 amplifier offers high performance, high efficiency, low power consumption and extended duty cycles in a very compact half-rack/flat-back package. The MU290 Power Amplifier is a high quality, class A/B amplifier. This powerful yet compact amplifier utilizes Darlington pairs for linear operation and offers 90 watts per channel or 200 watts bridged into a 4 ohm load.
NetStreams Musica Power Amplifier Safety Before using your MU290 External Amplifier, please read this Owner’s Manual carefully to ensure optimum trouble-free performance. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. CAUTION TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER. NO USER - SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
NetStreams Musica Power Amplifier Safety (continued) 5. The amplifier should only be connected to 120 VAC, 60 cycle grounded power supply. To avoid defeating the ground polarization of the power plug, do not remove the ground pin on the plug and check the outlet for correct polarization before plugging in the amplifier’s power cord. 6. Route power cord and other cables so that they are not likely to be walked on, tripped over, or stressed.
NetStreams Musica Power Amplifier Features This section of the manual provides an overview of the features that make this amplifier unique. Note: Observe proper polarity in interconnecting all system components. Caution: Do not connect AC power until all other connections are made. RJ45 Input/output The amplifier has been designed for the NetStreams product line and has features that allow for a simple installation and the ability to add more products as they become available.
NetStreams Musica Power Amplifier Configuration for Stereo Operation Input Connections Run a Cat5e cable from the Keypads Audio Port (EIM) output, to the input of the MU290. Output Connections RJ45 Output The RJ45 Terminator Plug comes installed in the MU290 but can be removed to add additional MU290’s or an Audio Port. If an Audio Port is not used then the RJ45 Terminator plug will need to be installed in the last MU290 of the chain. See figure 1.
NetStreams Musica Power Amplifier Configuration for Bridged (Mono) Operation The MU290 Power Amplifier may also be operated as a powerful single-channel amplifier. This “bridged” mode requires special attention to input and output wiring configurations. Input Connections The right and left audio signal will need to be summed together in order to have both channels play out of one speaker. This will need to be done by the installer.

NetStreams Musica Power Amplifier Mounting Your MU290 amplifier can be easily mounted in one of several ways: 1) on a shelf, 2) mounted to a wall using the brackets included, or 3) mounting in a cabinet using the brackets included. Remember that the MU290 will need to be installed in a well ventilated area. Special Consideration ¾ Allow ample ventilation; do not enclose the amplifier so air can not move freely around it, especially above it.
