In the USA the cord should comply with the requirements contained in the Standard for Cord Sets and Power Supply Cords, UL 817, be marked VW-1, and have an ampacity rating not less than the marked rating of the apparatus. Martin Audio – DX1 Speaker Management System...
UNPACKING THE DX1 Each Martin Audio DX1 controller is built, tested and thoroughly inspected to the highest standard before leaving the factory. After unpacking the unit please examine it for any signs of transit damage and inform your dealer if any such damage is found.
Factory presets can easily be updated by downloading the current file via a PC. The DX1 can also be used as a fully configurable electronic crossover system incorporating all of the features listed below.
LED displays between -24dB and -3dB of headroom, with the orange LED set at -3dB. The top, red LED is set at the limiter threshold for that channel. 12. Mute Keys - Six output mute keys with LED indicator. Martin Audio – DX1 Speaker Management System...
XLR Inputs and Outputs - 3 pin XLR connectors are provided for each audio input and output. All terminations are fully balanced, pin 2 Hot, pin 3 Cold and pin 1 Screen (shield). Martin Audio – DX1 Speaker Management System...
APPLICATIONS GUIDE OPERATING THE DX1 The DX1 can be used in two ways: 1. Using pre loaded factory presets to configure the DX1 for use with Martin Audio products. 2. As a generic digital loudspeaker management system. Note: this requires the user to configure the DX1 manually, i.e. by entering crossover information via the controls on the front panel.

It should also be noted that the turnover frequency displayed on the DX1 is the -3dB point for all slopes except 24dB Linkwitz-Riley where the -6dB point is shown. If the -6dB point is to be used for the Bessel or...
APPLICATIONS GUIDE 10.2 Time Alignment A further advantage of the DX1 over conventional products is the provision of an independently adjustable delay section for each output. This allows the true arrival time from multiple drivers to precisely aligned rather than relying on the compromise 'phase adjust' approach.
Parametric filters are carefully implemented using Double Precision processing. This method is costly in terms of processing power but yields substantial benefits in terms of the DX1’s exceptional noise performance and greatly improved low frequency stability. To adjust parametric settings: Use the FREQ control for the frequency.
To adjust limiter settings: Use the FREQ control to adjust the attack time. Use the Q control for the release time. Use the GAIN control for the limiter threshold. Martin Audio – DX1 Speaker Management System...
Each output and input has an individual gain screen. The outputs have a range of +15dB to –40dB, adjustable in 0.1dB steps and the inputs have a range of +6dB to –40dB, again adjustable in 0.1dB steps. To adjust the gain: Use the GAIN control. Martin Audio – DX1 Speaker Management System...
Gang Inputs: Gangs A and B inputs so that precise adjustments can be made to both inputs simultaneously. In this mode the LCD will show A+B when either of the input ‘GAIN’ buttons are pressed. Martin Audio – DX1 Speaker Management System...
IMPORTANT - Please Note that once the security system is initiated only re-entering the correct code will 'unlock' the DX1's functions. Please note the code! If the security code number is inadvertently lost contact your local Martin Audio sales office.
The DX1 has a RS232 external interface. This allows the factory presets in the DX1 to be updated via a PC. Updates will occur when new products that require the use of a controller are released. Instructions on how to load the latest factory preset file will be supplied with the factory preset file and it’s accompanying downloading software.

‘Wake up’ sequence which ramps up the output level over a set time period. The default is a wake up time of 10 seconds. The DX1 remembers exactly how it was set up before it was switched off. This includes which preset or user memory was loaded and the associated gain, delay and limiter levels etc.
