Loosen the terminal screws. Loosen Slotted screwdriver Cable preparation approx. 20 mm Tab * The explanation uses tabbed Euroblock plugs. • Use stranded wire for Euroblock connections, and strip the wire as shown in the illustration. With a Euroblock connection, the stranded wire may be prone to breakage because of metal fatigue due to the weight of the cable or due to vibration. Cables connected to the [INPUT]/[OUTPUT] connectors should be fastened to the tab of the Euroblock plug (3-pin) using the included cable ties (see illustration at right). When rack-mounting the device, use a lacing bar when possible to bundle and secure the cable. NOTE Use a slotted screwdriver with a blade width of 2 mm or less for the [GPI] connector’s Euroblock plug (16-pin), and a blade width of 3 mm or less for the [INPUT]/[OUTPUT] connector’s Euroblock plug (3-pin). 3 mm or less NOTE Do not tin (plate with solder) the stranded wire. 2. Insert cables. + – G • If cables will be frequently connected and disconnected, as in the case of a portable system, we recommend that you use ferrules with insulation sleeves. Use a ferrule whose conductor portion has an external diameter of 1. 6 mm or less (1. 3 mm or less for the [GPI] connector) and a length of approximately 7 mm (approximately 5 mm for the [GPI] connector) such as the AI 0, 5 - 6 WH made by the Phoenix Contact corporation. approx. Securely tighten the terminal screws. Pull the cables (not too strongly) to confirm that they are securely connected. 1. 6 mm or less (1. 3 mm for the GPI connector) 4. For the Euroblock plugs (3-pin) of the [INPUT]/[OUTPUT] connectors, use the included cable ties to fasten the cable to the tab. NOTE Trim off the extra portion of the cable tie as necessary. MTX3 Owner’s Manual 11 Controls and Connectors 5. Plug the Euroblock plug into the [GPI] connector or [INPUT]/[OUTPUT] connector of the MTX3. NOTE When connecting unbalanced cables to the [INPUT] connector, use a jumper wire to connect the “-” and “G” of the Euroblock. + – G 12 MTX3 Owner’s Manual Quick Guide This section explains basic settings and connection procedures for constructing an MTX system using the MTX3. Some of the steps may not be necessary for your system; if so, proceed to the next step. Preparations Use MTX Editor to make the required settings before you actually install and connect the equipment. 7. The audio signal flow in the MTX3 and the principal parameters to be set are as follows. Make the settings in the order shown. For details on each item, refer to “MTX Editor User’s Manual. ” Input port settings (e. g. , HA gain, +48V on/off) 1. Prepare a computer in which to install MTX Editor. The computer must meet the following requirements. • OS: Windows7 Home Premium or higher • Recommended specifications: CPU : Core i3/5 or better Memory : 4GB or more HDD : 50 MB or more free space Input patching Input channel settings (e. g. , gain, HPF, EQ) Matrix 2. Install MTX Editor in your computer. For details on installation, refer to “MTX Setup Manual. ” Matrix/zone settings 3. Specify the IP address and subnet mask of your computer. Enter “192. 168. 0. 253” as the IP address and “255. 255. 255. 0” as the subnet mask. Router 4. If you want to play back music or other audio files from the MTX3 itself, prepare an SD memory card. Copy the audio files to your SD memory card. For details on SD memory card handling, refer to “Using the MTX3 to play audio files saved on an SD memory card” (page 18). Output channel settings (e. g. , output level, delay/ room EQ, speaker processor) Output patching Output port settings (e. g. , polarity, output gain) 5. Start up MTX Editor. For details on installing and using MTX Editor, refer to “MTX Setup Manual” and “MTX Editor User’s Manual. ” As necessary, make input patching and output patching settings to specify the audio signal flow of the devices connected to the MTX3’s [INPUT] /[ST IN]/[OUTPUT]/ [YDIF] connectors. [. . . ] If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. [. . . ]
