Getting Started Thank you for purchasing the Yamaha Signal Processor MRX7-D. This manual will help you take full advantage of the superior functionality offered by the MRX7-D. After you have read the manual, keep it in a safe place for reference when needed. Included items (please check) • MRX7-D Owner’s Manual (this document) • Power cable • Euroblock plugs (16-pin, 3.50mm pitch) (2) • Euroblock plugs (3-pin, with tab, 5.
Introducing the MRX7-D Features • A signal processor that features the audio processing required for optimizing the acoustics of installed systems The MRX7-D is a high-performance, high-quality sound signal processor that features the audio processing required for optimizing the acoustics of installed systems.
Controls and Connectors Front Panel q we t yu i !1 !2 !5 88 r q SD memory card slot o !0 !4 !3 !0 [SYNC] indicators You can insert an SD memory card here. Music or sound effects can be played back from an SD memory card containing audio files (MP3 files and WAV files). Before you insert an SD memory card into the slot, or remove an SD memory card from the slot, remove the slot cover. For details on SD memory card handling, refer to page 21.
Controls and Connectors Rear Panel q e w r ty u i o !0 !3 !1 !2 !4 t [RS-232C] connector NOTE The MRX7-D has some connectors that are shaped identically but have a completely different function (e.g., [DCP] connector, Dante [PRIMARY]/[SECONDARY] connectors, [YDIF] connectors). Make the appropriate connections as instructed by the explanation for each connector. Otherwise, you risk damaging your equipment. q AC IN connector Use the included power cord to supply power to this connector.
Controls and Connectors Switches 1–2 (UNIT ID) These switches specify the upper digit and the abovementioned [UNIT ID] rotary switch specifies the lower digit, together allowing you to specify one of 63 different UNIT ID numbers in a range from 01 to 3F. Switch position Option Functions UNIT ID is “0x” The [UNIT ID] rotary switch will have a setting range of 01 through 0F. UNIT ID is “1x” The [UNIT ID] rotary switch will have a setting range of 10 through 1F.
Controls and Connectors o [YDIF] connectors These connectors are used to make a ring connection with the devices that comprise the MTX/MRX system, allowing digital audio signals to be transmitted and received. Use CAT5e or better Ethernet STP cables (shielded twisted pair cables) that have all eight pins connected in a straight connection. The maximum cable length between devices is 30 meters, and you can connect up to eight devices that are equipped with the [YDIF] connectors.
Controls and Connectors Euroblock plug connection 1. Loosen the terminal screws. Use the included Euroblock plugs when making connections to the [INPUT]/[OUTPUT] connectors and [GPI] connector. Loosen Slotted screwdriver Cable preparation Terminal screw approx. 7 mm (approx. 5 mm for the GPI connector) Euroblock plug approx. 20 mm • Use stranded wire for Euroblock connections, and strip the wire as shown in the illustration.
Controls and Connectors 5. Plug the Euroblock plug into the [GPI] connector or [INPUT]/[OUTPUT] connector of the MRX7-D. 3. Align the edges of the card with the guide rails inside the slot, and insert the card into the slot. Push the card all the way into the slot so that the connector at the end of the card is correctly inserted into the connector inside the slot. NOTE When connecting unbalanced cables to the [INPUT] connector, use a jumper wire to connect the “-” and “G” of the Euroblock.
About Dante This product features Dante technology as a protocol to transmit audio signals. Dante is a network protocol developed by Audinate. It is designed to deliver multi-channel audio signals at various sampling and bit rates, as well as device control signals over a Giga-bit Ethernet (GbE) network. Dante also offers the following benefits: • It transmits up to 512 in/512 out, for a total 1024 channels (in theory) of audio over a GbE network.
About Dante About redundant networks About Dante Controller A redundant network consists of two circuits, a primary circuit and a secondary circuit. Normally, the network operates on the primary circuit. However, if the primary connection is broken, the secondary circuit will automatically take over audio communications. Therefore, using a redundant network with a star topology would increase resiliency against unexpected network problems relative to a daisy chain network.
Quick Guide This section explains basic settings and connection procedures for constructing an MTX/MRX system using the MRX7-D. Some of the steps may not be necessary for your system; if so, proceed to the next step. Preparations Use MTX-MRX Editor to make the required settings before you actually install and connect the equipment. 1. Prepare a computer in which to install MTXMRX Editor. 6. The audio signal flow in the MRX7-D and the principal parameters to be set are as follows.
Quick Guide On-site work (Installation and wiring) Install and connect the system while referring to the schematic diagram you printed out. 1. Set the UNIT ID of the MRX7-D and the XMV/ EXi8/EXo8. Set the UNIT ID for every MRX7-D and XMV/EXi8/EXo8 device. The UNIT ID is specified by the combination of the [UNIT ID] rotary switch and DIP switches located on each device’s rear panel. Set each device to a different UNIT ID so that no conflict occurs. 2.
Various Procedures Recalling (switching) presets Using the scheduler With the MTX/MRX system, input/output port patching, matrix mixer settings, and the parameters of XMV amps within the same MTX/MRX system are stored together as a “preset” in the MRX7-D and in MTX-MRX Editor for recall when desired. Each MTX/MRX system can store 50 presets. MTX-MRX Editor is used to edit presets. The scheduler can switch presets or play music and sound effects from the SD memory card at the date and time you specify.
Various Procedures Connecting via the [GPI] connector GPI (General Purpose Interface) devices can be connected to the rear-panel [GPI] connectors. GPI allows a variety of control signals to be exchanged with external controllers or other devices. • Connection examples using the [GPI IN] connector Example: Controlling the MRX7-D from a switch box MRX7-D +5VDC +V CPU IN A/D 100k Example: Controlling the MRX7-D with a 10k ohm linear taper potentiometer.
Various Procedures Using the MRX7-D to play audio files saved on an SD memory card The MRX7-D can use commercially available SD memory cards to play back audio files such as music and sound effects without needing to connect a CD player or other audio device. The MRX7-D can play back audio files in either MP3 or WAV formats. Initializing the MRX7-D Here’s how to initialize the MRX7-D’s internal memory, restoring it to the factory settings. 1. Power-off the MRX7-D. 2.
Various Procedures 4. When initialization is completed, power-off the MRX7-D once again. 5. Set the rear panel DIP switches 7 and 8 to the “RESUME” position. 6. Power-on the MRX7-D again. The MRX7-D will start up in its factory-set state.
Appendix Troubleshooting The Yamaha Pro Audio website provides a FAQ (a list of frequently asked questions, with answers). http://www.yamahaproaudio.com/ Symptom Possible cause, and action Connect the power cord properly. The device does not turn on, or the panel LEDs do not light up. Make sure that the power switch is turned on. If the power still does not turn on, contact your Yamaha dealer.
Appendix Symptom Preset does not switch at the time specified by the scheduler. The [ALERT] indicator is flashing. Can’t switch presets from a device connected to the [GPI] connector. Possible cause, and action The MRX7-D’s clock is set by sending clock data from the computer via MTX-MRX Editor to the MRX7-D. Make sure that the computer’s clock is set correctly.
Appendix Messages Warnings and certain other types of information are displayed via the MRX7-D front panel indicators. Messages are also displayed in the Dante Controller Error Status field. Each indicator lights or flashes as described below: Unlit The indicator is off. Lit The indicator remains lit steadily. Flash The indicator continues to flash. Flash x 2 The indicator flashes twice cyclically. NOTE You can make settings in MTX-MRX Editor so that the [SYNC] indicator will remain unlit.
