MB01-001 Matching Box SM72 Installation and Operation Manual Section 1.0 Description 1.1 Introduction Information in this section consists of product description, design features and specifications for the MB01-001 Matching Box. All derivative product information shall be contained in the applicable manual supplement, which may be obtained from AEM as required. Review all notes, warning and cautions. 1.2 Purpose of Equipment The MB01-001 is a remote mounted audio level matching unit for 8 transceivers and 10 receivers. It provides 8 floating key signals and is capable of providing unamplified artificial sidetone. The unit also provides a diode OR’ed DF Mute signal when any of the transceivers are keyed. 1.3 Design Features The MB01-001 is made up of 8 subassemblies: 2 ‘Receiver’ subassemblies, 4 ‘Transceiver’ subassemblies, one Test subassembly and one Backplane subassembly. Each ‘Receiver’ subassembly supports 5 receivers and each ‘Transceiver’ subassembly supports two transceivers. The Test subassembly connector provides the installing agency access to all microphone and receive signals while all the equipment is connected. This allows proper level adjustments to be made while all inputs and outputs are loaded. The MB01-001 supports real sidetone, dedicated sidetone inputs (with 6dB of attenuation) and can generated unamplified artificial sidetone. All connectors are labelled to assist with proper connection to the airframe wiring. 1.4 Specifications 1.4.1 Electrical Specifications Input Signals Quantity 18 Receive inputs 8 Microphone inputs 8 Sidetone inputs Audio level 4.9 Vrms nominal for receiver inputs. 4.9 Vrms nominal for sidetone inputs. 1 Vrms nominal for microphone inputs.

MB01-001 Matching Box SM72 Installation and Operation Manual 2.4.2 Cautions CAUTION: All audio installations can be seriously degraded by incorrect wiring and shielding, and may result in abnormal cross-talk, hum and ground-loop noise. Be especially careful with all microphone wiring and tie line wiring, as these lines carry the lowest level signals in the aircraft. 2.4.3 Cabling and Wiring All wire shall be selected in accordance with the original aircraft manufacturer's Maintenance Instructions or AC43.13-1B Change 1, Paragraphs 11-76 through 11-78. Unshielded wire types shall qualify to MILW-22759 as specified in AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. For shielded wire applications, use Tefzel MIL-C-27500 shielded wire with solder sleeves (for shield terminations) to make the most compact and easily terminated interconnect. Follow the connector map in Section 2.6 as required. Allow 3" from the end of the shielded wiring to the shield termination to allow the connector hood to be easily installed. Reference the interconnect drawing in Section 2.6 for shield termination details. Note that the hood is a "clamshell" hood, and is installed after the wiring is complete. Aircraft harnessing shall permit the unit to be removed from the panel for easy access to all side adjustments. Do NOT mount the unit until all adjustments have been performed. Maintain wire segregation and route wiring in accordance with the original aircraft manufacturers Maintenance Instructions. Unless otherwise noted, all wiring shall be a minimum of 22 AWG, except power and ground lines, which shall be a minimum of 20 AWG. Reference the Interconnect drawing for additional specifications. Check that the ground connection is clean and well secured, and that it shares no path with any electrically noisy aircraft accessories such as blowers, turn and bank instruments or similar loads. Power to this unit must be supplied from a separate circuit breaker or fuse (fast blow), and not attached to any other circuit breaker without additional protection. Verify that the selected circuit breaker size and wire gauge are adequate for the installation using the techniques specified in AC43.13-1B Change 1, Paragraphs 11-47 through 11-51 and 11-66 through 11-69. 2.4.4 Post-Installation Checks 22.214.171.124 Voltage/Resistance Checks Do not attach the MB01-001 until the following conditions are met. Check the following for Transceiver Subassemblies: a) Check P101, pin <10> for continuity to ground (less than 0.5 ). b) Check P102, pin <10> for continuity to ground (less than 0.5 ). c) Check P104, pin <10> for continuity to ground (less than 0.5 ). d) Check P105, pin <10> for continuity to ground (less than 0.5 ).

MB01-001 Matching Box SM72 Installation and Operation Manual Check the following for Receiver Subassemblies: a) Check P103, pin <4> for continuity to ground (less than 0.5 ). b) Check P106, pin <4> for continuity to ground (less than 0.5 ). Check the following for Test Subassembly: a) Check P107, pin <1> for continuity to ground (less than 0.5 126.96.36.199 ). Power On Checks Power up the aircraft’s systems and confirm normal operation of all functions of the MB01-001. Refer to Section 3 (Operation) for specific operational details. a) Check preset adjustments are completed before aircraft departure. Upon satisfactory completion of all performance checks, make all required log book entries, electrical load, weight and balance amendments and other documentation as required by your local regulatory agency before releasing the aircraft for service. 2.5 Adjustments and Connections The unit is shipped from the factory with all internal adjustments set to the normal test levels. Once installed in the aircraft, it may be desirable to change some of these settings to best suit the local operating environment. The internal adjustments are located through the top cover. See Figure 1. Figure 1: Internal Adjustments All microphone, receive and artificial sidetone adjustments are 10-turn trimpots. The dedicated sidetone inputs are not adjustable.
