Mains Fuse - located in a finger-proof holder adjacent to the mains inlet. (A spare fuse is also located inside this holder) Important - Always replace the fuse with the correct type and rating as shown on the rear panel legend. Mains Inlet - connected via a standard IEC socket. External - 9 pin D-type connector for preset loading via RS232 PC link. See later for DX1. 5 preset loading instructions. Outputs 1 - 6 ­ a 3 pin XLR socket is provided for each output. All are fully balanced, pin 2 hot, 3 cold, 1 screen. Recessed AES input switch - to select AES digital inputs. Red LED will illuminate in the hole when AES inputs are selected, along with the corresponding front panel indicator. Inputs A & B ­ a 3 pin XLR socket is provided for each input. Both are fully balanced ­ pin 1 = screen, pin 2 = hot, pin 3 = cold. Input A is also used as a 2ch AES digital audio input when AES mode is selected. 12) Operating your DX1. 5 Start-up procedure Switching on the unit will display a brief message detailing the unit type and software version running and all LEDs will briefly illuminate. The unit will then begin its countdown to the wake-up procedure, during which time the audio will fade up to the level last set. Metering will begin to operate when the fade-up starts. Preliminary Set-up The procedure below should be followed when first installing a DX1. 5 unit. To do this, press MENU, and use the BACK or NEXT key to select `Crossover sub-menu' and then press ENTER. Use the BACK or NEXT key to select `Design a crossover' and then press ENTER. Finally, use the BACK or NEXT key to select the desired routing and follow the set-up wizard to finalise your design. [. . . ] Selecting Input and Crossover during a Store will skip any memories that have other combinations in them. Selecting Erase for any combination will show only locations that have EXACTLY that combination ­ it is not possible to erase just one part of a combination memory. The DX1. 5 has 256 memory locations, but these are dynamic in nature ­ obviously a memory containing Input and Crossover settings takes up more space than one containing just Input settings. 18) Loading new software via a pc The unit's internal software may be updated via the RS232 port ONLY, one unit at a time using the pc loader software. Your Martin Audio distributor or dealer will let you know if updates are necessary. 19) AES Inputs DX1. 5 units have AES input facilities (via input XLR A) built in as standard. [. . . ]
