user manual LMS-D6 Introduction The LMS-D6 is a compact and powerful DSP based audio-processing unit, ideally suited for live applications, where it combines the functions of multiple conventional products in a compact 1U high unit. To achieve this the LMS-D6 has 2 inputs and 6 outputs, which can be configured in 5 basic modes, 3 x 2 way, 2 x 3 way, 4 way, 5 way and 6 way crossover. Each input has gain and delay.

user manual LMS-D6 OPERATING THE LMS-D6 Preliminary Set-up The following procedure should be followed when first installing the LMS-D6. Recall a Factory Preset To do this press ‘MENU’, use the ‘BACK’ or ‘NEXT’ key to select ‘Xover sub-menu’. Press Press ‘ENTER’; use the ‘BACK’ or ‘NEXT’ key to select ‘Load a Xover’. Press ‘ENTER’, use the ‘BACK’ or ‘NEXT’ key to scroll through the preset programs. Press ‘ENTER’ when the desired program appears. The crossover will automatically load.
user manual LMS-D6 System Sub-Menu: Sub-Menu System Status: Displays unit information including software version and temperature. LCD Contrast: Adjusts LCD contrast. LED Brightness: Adjusts LED brightness. Temperature Alarm: Sets a temperature warning value in Centigrade. Wake-up Time: Sets whether or not the unit starts up in mute. Output Meters: Selects output meters to be pre or post mute. Filter Q or BW: Selects whether Q or bandwidth is displayed in the parametric screens.
user manual LMS-D6 LMS-D6 CONFIGURATIONS Introduction To simplify set-up of the LMS-D6, 5 crossover modes are menu selectable. These all have parametric equalisers, high and low pass filters, limiters, gain and delay. 2 x 3 way and 3 x 2 way crossover modes have the option available to provide precise 'ganged' parameter adjustment for stereo sources. Crossover Modes All crossover modes feature adjustable crossover frequencies with a choice of slopes, 5 bands of driver compensation E.Q.
user manual LMS-D6 Time Alignment A further advantage of the LMS-D6 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. Delay time is adjustable in 2..6µS steps (1mm).
user manual LMS-D6 FUNCTION SCREENS Parametric Equaliser Screen OP1+4 Low PEQ: 1 Ο 1K00Hz B=.34 0.0dB All modes feature a total of 30 bands of fully flexible parametric equalisation (5 per output), with all sections selectable to Low or High frequency shelving response. Each parametric section can be positioned at a frequency from 20Hz to 20kHz and features a wide range of 'Qs’ to produce response curves ranging from broad to notch. The gain control ranges from +15dB to -30dB in 0.1dB steps.
user manual LMS-D6 High and Lowpass filter Screens OP1+4 Low HPF < 10Hz Bessel 24dB Each output has an independent high pass filter and an independent low pass filter. Both filters have a range of selectable slopes, which are Bessel 12dB, 18dB and 24dB, Butterworth 12dB, 18dB and 24dB, and Linkwitz Riley 24dB. Highpass filters have a range of <10Hz (through) to 16kHz and Lowpass filters have a range of 22kHz (through) to 59Hz in 1/36 octave steps. HPFs and LPFs can be asymmetrical set.
user manual LMS-D6 Limiter Screen OP2+5 Mid Limiter Atk:4.0mS Rx16 +22dB Each output has an independent high performance limiter. All limiters have an attack range of 0.3mS to 90mS, release times are 4, 8, 16 and 32 times the attack time and thresholds range from +22dB to –10dB in 1dB steps. If the automatic limiter time constant option is in use, all limiter screens will say ‘automatic’ and the time constants will be set from the Highpass filter frequency. A table of dB to Vrms is in appendix 1.
user manual LMS-D6 Delay Screen OP1 Low Delay = 1.003mS Each output has an independent delay time control. This can be adjusted in 2..6µS steps or in 1mS steps giving complete control over driver time alignment. Input delay (base delay) is adjustable in 1mS steps only. To adjust delay settings: Use the ‘FREQ’ control for coarse control. (1mS steps) Use the ‘Q’ control for fine control. (2..6µS steps) Polarity Screen OP1 Low Polarity = [ + ] Each output has an independent polarity screen.
user manual LMS-D6 Gain Screen O/P1+3 LOW Gain = 0.1dB 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. X-over Sub-Menu Press 'MENU' and select X-over Sub-menu using the ‘BACK’, ‘NEXT’ and 'ENTER' keys. Three options are available in this sub-menu which are: Load a Xover Loads a stored crossover.
user manual LMS-D6 Lock options: Changes only: This option locks all parameters so that no changes can be made, including all menus. Changes + view: This option locks all parameters and the viewing of them on the LCD including all menus. Changes + mutes: This option locks all parameters, including all menus, and disables all mute keys. Everything: This option locks all parameters and the viewing of them, including all menus, and disables all mute keys.
user manual LMS-D6 Interface Sub-Menu Press 'MENU' and select X-over Sub-menu using the ‘BACK’, ‘NEXT’ and 'ENTER' keys. Interface Setup Opens a wizard to configure the remote interface. Baud rate can be configured to down load new presets. AES / EBU Sub-Menu Connection of AES/EBU signals is via the existing rear panel XLR connectors. Menu Selections With the AES/EBU option fitted, AES Receive and Diagnostic modes are provided.
