The subs may be stereo or mono by properly ...
Powered Main Loudspeakers and Subwoofers with Separate Stereo Full‐Range Loudspeakers The Martin Audio DX0.5 Loudspeaker Management system is also useful for controlling powered loudspeakers and subwoofers. Here, the DX0.5 is configured using the ‘2xStereo+Subs’ setup type. The left and right line‐level XLR outputs from a mixer feed the A and B XLR inputs of the DX0.5. XLR outputs 1 and 2 of the DX0.5 feed the XLR inputs of two Martin Audio DD12 powered loudspeakers. These loudspeakers are located on stage. XLR outputs 3 and 4 of the DX0.5 feed the XLR inputs of another two Martin Audio DD12s. This full‐range pair should be positioned halfway toward the rear of the venue with delay added so they are time‐aligned with the main pair. Finally, XLR outputs 5 and 6 of the DX0.5 feed the XLR inputs of two Martin Audio PSX powered subwoofers that are located on stage and paired with the DD12 loudspeakers. In this setup, the DX0.5’s high‐ and low‐pass filters on outputs 1 and 2 and 5 and 6 may be used to configure a crossover between the DD12 and PSX for added control from the processor. Care should be taken when configuring the DX0.5’s crossover so the PSX built‐in crossover does not conflict. The subs may be stereo or mono by properly configuring the input sources for DX0.5 outputs 5 and 6. The DX0.5 may be used for additional room corrective EQ and delay to align the loudspeakers and subwoofers and a limiter added for extra protection against over powering from irresponsible DJs for example.

XLR outputs 1, 2, 3 and 4 of the DX0.5 feed the XLR inputs of a pair of MA3.0 amplifiers. The CH 1 and CH 2 NL4 speaker outputs of these power amplifiers feed the Phoenix inputs of the top and bottom of a stereo pair of 16 module Omniline arrays XLR output 5 of the DX0.5 is connected to the A & B XLR main inputs of a Martin Audio MA5.2K; it is only necessary to connect a cable to input A as the amplifier has a link switch to parallel both inputs. The CH 1 and CH 2 NL4 speaker outputs of this power amplifier feed the Phoenix input of a pair of CSX212 passive subwoofers The DX0.5’s high‐ and low‐pass filters on output channels 1–5 may be configured to create a crossover to optimize the subwoofers with the Omniline. The subs are run mono by properly configuring the input sources for DX0.5 output 5. The DX0.5 may be used for adding the PEQ recommended by the Omniline software and any additional room corrective EQ. Delay to align the loudspeakers and subwoofers can be added and a limiter for protection of the system. HAM09224 User Guide V1.0 13 ...

DX0.5 USER GUIDE Gain/Mute/Lim The first and possibly most important tab is the Gain, mute and limiter page;‐ From this page you can view the input and output levels, adjust gain, mute channels and set limiter parameters. Gain Gain is adjustable for both inputs and all six outputs using either the gain fader which can be dragged and dropped to any value required or alternatively specific values can be typed into the Gain value window. Input gain can be adjusted from ‐15 to +15dB. Output gain from ‐12dB to +6dB. The faders default to the zero position therefore are in a slightly different vertical position due to the different scales. Here are am input and output fader for comparison;‐ HAM09224 User Guide V1.0 43 ...
DX0.5 USER GUIDE Mute is available on all input and output channels via the Mute button just to the right of the fader and below the VU meter. In normal, un‐muted mode the button is grey, when activated the channel is muted and the button turns red. Here are both un‐ muted and muted versions;‐ Metering Both input and output channels feature multi‐segment bargraph‐style VU Meters which have a scale from ‐20dBu to +18dBu with a clip segment right at the top. The output meters also feature a limit light above the bargraph to indicate limiter operation. In addition there is an option in the Limiter section change the output VU Meter function to indicate limiter activity. This changes the scale to read from ‐30 to ‐2 dB. Here are input and output VU meters plus and output meter configured to show limiter activity;‐ Limiters Limiters are available to protect the speaker system connected to each output;‐ These have fully adjustable controls for the Threshold; the level in dBu at which the limiter will activate. This can be adjusted from ‐10 to 20dBu. 20dBu is the default which is essentially out of circuit. Values can be adjusted up and down using the two arrowed buttons or specific values typed directly into the window. Attack time is the time in milliseconds before which the limiter will operate; a shorter time acts like a clip limiter stopping virtually all signals from exceeding the threshold level, a slower time will allow short‐term peaks to pass through whilst still restricting the long term power keeping it to within levels at which the drivers will avoid damage. As with threshold the values can be cycled up HAM09224 User Guide V1.0 44 ...

DX0.5 USER GUIDE and down using the arrowed buttons or values can be entered by directly typing them into the window. Values can range from 5ms up to 200. Steps are 1ms from 5 to 20ms, 5ms from 20 to 30ms, 10ms from 30 to 100ms then 20ms from 100 to 200. Release is the time in seconds that it takes the gain to return to normal after levels drop back below the limiter threshold. A slower release helps to make the limiter less audible reducing the "pumping" sound that is often audible. As with threshold and attack the values can be cycled up and down using the arrowed buttons or values can be entered by directly typing them into the window. Values can range from 0.1s up to 3s in steps of 0.1seconds. HAM09224 User Guide V1.0 45 ...
DX0.5 USER GUIDE Routing The routing tab allows you to configure the routing from the two input channels to the six output;‐ This page also allows quick access to the pages for other adjustments;‐ Clicking on any other the input or output boxes will bring up the output naming window. Clicking on any of the Gain or Limiter boxes will open the Gain/Mute/Lim tab. Clicking on a Polarity or Delay box will take you to the Delay Tab. Clicking on PEQ or X‐over will open the input or output channel tab depending on which box is clicked. The routing from inputs A and B will be pre‐determined by your choice of system configuration but can be freely modified to suit your requirements by simply clicking on the nodes to show a tick. Not that all outputs must have at least one input routed, they cannot be left un‐routed (but can of course be muted if you don't need to use a channel). Both nodes can be clicked to run the output channel from a mono signal derived from both input channels;‐ HAM09224 User Guide V1.0 46 ...

A second click will put the EQ back in place. 'FLAT' as the name suggests resets the gain of all filters to 0dB. Frequency and Q factor values are retained but any gain settings are lost. Note that previous values cannot be restored unless you have stored your settings as a Preset, they will have to be manually re‐entered. The next features is the EQ type which offers a drop‐down with the filter types available;‐ All filters are Bell by default but may be configured as High Shelf with either a 6 or 12dB per octave slope, or Low Shelf, also with 6 or 12dB per octave slopes. Finally there are three fader controls to adjust the parameters of each filter; Gain, Frequency and Quality factor, or if high or low shelf filters are selected Gain and Frequency;‐ HAM09224 User Guide V1.0 50 ...
