MP 101 Series 1 Chapter One Introduction About this Manual About the MP 101, MP 101 AAP, and MP 101 D Features
Introduction About this Manual This manual contains information about the MP 101, the MP 101 AAP, and the MP 101 D microphone to line preamplifiers and provides instructions on how to mount and operate these units. About the MP 101, MP 101 AAP, and MP 101 D The Extron MP 101, MP 101 AAP, and MP 101 D (the MP 101 Series) are high quality microphone to line level audio preamplifiers. These products can add microphone capability to most Extron audio and switcher systems.
Flexible mounting options — The MP 101 can be mounted on a rack, on a table, or under furniture. The MP 101 AAP mounts into various Extron architectural products. The MP 101 D is wall mountable using standard, off-the-shelf mounting accessories. External international power supply — The autoswitchable, 12 VDC, 1 A external power supply provides worldwide power compatibility (Extron part #70-380-01).

The blue connector does not have the extended tail or the included tie-wrap. C Do not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and can be easily pulled out. They may also break after being bent several times.
MP 101, cont’d Remote connection d Remote — An optional 3-pin, captive screw connector allows a wall mounted audio controller or MediaLink product to remotely control volume and mute levels for the MP 101 unit. See “Remote Control”, later in this chapter, for more information. Audio output (line level) e Line Output — A 3-pin, captive screw connector outputs to audio mixers, amps switchers, or other non-microphone audio equipment.
Mounting the MP 101 There are many optional accessories for mounting the MP 101. They include the following: Projector mounting options • PMK 100 Mini Projector (part #70-217-01) • PMK 300 Multi-Product Projector (part #70-374-01 ) • PMK 350 Low Profile Multi-Product Projector (part #70-563-02/03 ) Rack mounting options • RSF 123 1U 3.5" Deep (part #60-190-20) • RSB 123 1U 3.
MP 101, cont’d Rack installation The MP 101 can be rack mounted using either the VersaTools 19" 1U rack shelf (part #60-190-20), basic VersaTools rack shelf (part #60-604-20), a standard universal 1U rack shelf (part #60-190-01), or a 1U basic rack shelf (part #60-604-01). The figure below shows the VersaTools rack shelf, and the figure on the following page shows a standard rack shelf.
1U Universal Rack Shelf 1/2 Rack Width Front False Faceplate 1/4 Rack Width Front False Faceplate 1/8 Rack Width Front False Faceplate Both front false faceplates use 2 screws. (2) 4-40 x 3/16" Screws Use 2 mounting holes on opposite corners. Back of the rack installation The MP 101 can be conveniently mounted on the rear of a rack by using the Extron MBB 100 Back of Rack Mounting Kit (part #70-367-01). This mounting option allows the MP 101 to be vertically positioned. 1.
MP 101, cont’d Inside Outside Furniture mounting In addition to using the MP 101 on a rack, you can mount it on furniture using the optional MBU Mini Under-Desk Mount Kit (part #70-212-01). To use this option, do the following: 1. Remove the rubber feet if they were previously installed. 2. Attach one of the mounting brackets to the MP 101, as shown below. a. Remove the two machine screws from one side of the unit. Save these screws for future use. b.
b. At each mark, drill a 3/32" (2 mm) diameter pilot hole approximately 0.25" (6 mm) deep in the mounting surface. c. Insert provided #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 0.25" (6 mm) of the screw protrudes. d. Align the bracket slots with the wood screws and place the unit against the mounting surface. e. Slide the unit either forward or backward until the screws are in contact with the edge of the bracket slots.
MP 101, cont’d Remote Control The wiring and control options described below pertain to all models in the MP 101 series. Remote connector wiring As shown below, Pin 1 is 10 VDC reference voltage. Pin 2 is volume control DC voltage; range is 0 to 10 V, where 0 V is mute and 10 V provides maximum volume. Pin 3 is ground. N All nominal levels are at ±10%.

If there is minimal distortion, but greater volume is required, turn the Mic Gain potentiometer clockwise (towards the 75 dB mark) to increase the volume, but not past the point where distortion occurs.
MP 101 AAP, cont’d 4. Repeat steps 1 through 3 to mount any other AAPs. Cover any openings in the faceplate with blank plates (provided). 5. If it was not done previously, adjust the MP 101 AAP from its rear panel. See the previous section, “Adjusting the MP 101 AAP” for detailed instructions. 6. Pretest the MP 101 AAP before final mounting of the faceplate. 7. Perform the final mount by attaching the cabled device faceplate or AAP wallplate into a wall or piece of furniture.
Remote control options The MP 101 AAP has three remote control options: 1. The Extron VCM 100 volume/mute controller and VC 50 volume controller use a 10 k ohm potentiometer as the main method for controlling volume levels. The VCM 100 includes an illuminated Mute button and operates in sync with the MP 101 AAP. 2. The Extron MLA-VC10 converts RS-232 serial command to 0~10 volt variable DC for volume control. 3. Generic volume/mute controllers are standard 10 k ohm potentiometers.

1 2 3 3-pin Female Adjusting the MP 101 D Adjustment options for the MP 101 D are located on its rear panel (see “Rear Panel Features” in this chapter for details). Therefore, you must perform these adjustments before mounting into a wall. To adjust the MP 101 D, do the following: 1. If using a condenser microphone, set the Phantom power switch to the “on” position. If using a dynamic microphone, set the Phantom power switch to the “off” position. 2.
MP 101 D, cont’d N Before mounting, the MP 101 D should be tested to verify that its connections and settings are correct. To mount the MP 101 D into a Decora faceplate, do the following: 1. Secure all cables and connections onto the MP 101 D. 2. If it was not done previously, adjust the MP 101 D from its rear panel. See the previous section, “Adjusting the MP 101 D”, for detailed instructions. 3. Place the MP 101 D through the opening in the wall or furniture and into the wall box.

MP 101 Series 5 Chapter Five Architectural Installation Installation Instructions Preparing the Site and Installing the Wall Box
Architectural Installation Installation Instructions Two versions of the MP 101 series, the MP 101 AAP and MP 101 D, can be mounted into furniture, a wall, or an Ackermann floor box. For specific mounting instructions for each model, see “Mounting the MP 101 AAP” in chapter 4, and “Preparing the Site and Installing the Wall Box`” in chapter 5. Unless otherwise noted, both units (the MP 101 AAP and the MP 101 D) are referred to as the "MP 101" in the following instructions.
• If the MP 101 will be installed without a wall box (using mud rings or fastening it directly to the wall or furniture), measure and mark the surface for the cutout area indicated in the template. 3. Cut out the material from the marked area. 4. Check the opening size by inserting the wall box (if used) or the MP 101 (if no box is used) into the opening. The box and preamplifier should fit easily into the opening. Enlarge or smooth the edges of the opening if needed. 5.
Architectural Installation, cont’d • If the MP 101 AAP or MP 101 D are being installed in a two- or four-gang AAP plate, attach the wall box to the wall stud or furniture with nails or screws, leaving the front edge flush with the outer wall or furniture surface. See the illustration below, which applies to one-, two-, three-, and four-gang wall boxes.
