To access a channel press the appropriate channel’s ‘GAIN’ button. When you press the button once you will get that channel’s gain screen. To scroll through a channel’s parameters, use the ‘BACK’ and ‘NEXT’ keys. (If you press the gain button a second time, you will get the last parameter viewed. A third press will take you back to the default screen.)
To enter the menus, press the ‘MENU’ key. Use the ‘BACK’ and ‘NEXT’ keys to take you to the submenu you require. ‘ENTER’ will take you into the sub-menu you have selected. Use the ‘BACK’ and ‘NEXT’ keys to select the menu you require. Press ‘ENTER’ to take you into the menu selected.
‘BACK’ and ‘NEXT’ will then select the menu options. Use ‘ENTER’ to confirm selection.
MENUS:
X-over Sub-Menu: Used for storing and recalling X-overs including format, output EQ, output delay, output gain and limiter settings. Also used for designing a new X-over.
Security Sub-Menu: Used for locking various features of the unit with a unique 4 digit code.
System Sub-Menu: Used to view reports of the unit’s status. Other options include whether the parametrics are displayed in Q or bandwidth and if the meters are pre or post mute.
Notes:
1.The output meters show level, in dB’s, from limiter threshold. The input meters show level, in dB’s, from input clip.
2.HPF’s and LPF’s are defined independently on each channel.
3.To get access to the limiter attack and release, select ‘Auto Limiter TC’ to No, when designing a X-over.
4.To show parametric filters in bandwidth (‘BW’), rather than Q, go into the ‘system sub-menu’, select ‘filter Q or BW’, and select BW.

Important Safety Information
Do not remove Covers. There are no user serviceable parts inside, please refer servicing to qualified service personnel. This equipment must be earthed.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
DO NOT EXPOSE TO RAIN OR MOISTURE
ATTENTION
RISQUE DE CHOC ELECTRIQUE
NE PAS ENLEVER
NE PAS EXPOSER A LA PLUIE NI A L’HUMITE
It should not be necessary to remove any protective earth or signal cable shield connections.
Do not defeat the purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wider blade and the third prong are provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
Only use this equipment with an appropriate mains cord.
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.

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. Each output consists of a high and lowpass filter, 5 bands of parametric equalisation, limiter, delay, gain and polarity controls. User memories are provided, and also a multi-level security 'lock-out' function for all controls. The LMS-D6 is also available with optional AES/EBU inputs and outputs. The LMS-D6 is designed for quick adjustment via easy-to-use front panel controls.
Features
•Superb audio quality: carefully optimised double precision processing plus 40 bit internal data path for exceptional dynamic range and sonic quality.
•A flexible 2 input, 6 output multi-mode format featuring a choice of 3 x 2 way, 2 x 3 way, 4 + 2 way, 5 + 1 way and 6 way crossover modes with limiters.
•Each parametric section provides +15dB to -30dB of gain at centre frequencies between 20Hz - 20kHz with a wide range of Qs from 0.4 to 128. All parameters feature fine resolution with 1/36th octave frequency steps, 0.1dB gain increments and 100 Q settings. Any parametric section can be set for LF & HF shelving response.
•Six high performance limiters are provided, featuring a wide range of control over Attack, Release and Threshold parameters. The output meters shows headroom to the limit threshold. The meter time constants track the limiter time constants to show precise power usage.
•Variable high and low-pass filters for each output can be set for 12, 18 and 24dB per octave slopes with a choice of Bessel, Butterworth or Linkwitz-Riley responses. Independent control over high & low-pass functions allows asymmetric crossover functions to be realised.
•Three velocity-sensitive rotary encoders provide a familiar and easy to use control format with all filter information displayed simultaneously on a backlit LCD display.
•Delay of up to 650mS can be independently set for each output with a minimum increment of 2.6µS.
•Comprehensive standard specification includes 20 user memories, and Turbosound’s pre set memories.
•The LMS-D6 provides exceptional audio quality with a full >110dB dynamic range, high sampling rate and minimal filtering.
•AES / EBU digital inputs and outputs are available as an option.

1.LCD Display - Shows menu options, output information and various parameters being adjusted.
2.Gain Keys - Two input and six-output ‘gain’ keys allow instant access to the gain screen for each channel. Pressing a second time selects the last function edited.
3.Next Key - Moves the display forwards through the list of available parameters for the current input or output channel.
4.Back Key - Moves the display backwards through the list of available parameters for the current input or output channel.
5.Menu Key - Activates the main menu on the LCD display. Pressing a second time selects the last menu edited. Different menus are selected by pressing the ‘BACK’ and ‘NEXT’ keys or using the ‘FREQ’ control.
6.Enter Key - Enters the chosen menu and confirms menu selections.
7.OUT Key - Exits the menu.
8.Bypass Key - Allows the currently displayed parametric section to be bypassed. (Note: The Highpass / Lowpass filters and limiters can not be bypassed.)
9.Parameter Controls - The three velocity sensitive rotary encoders allow the relevant parameter, on the LCD screen, to be adjusted.
10.Input Meters - Displays available headroom before input clipping occurs. The bottom green LED is set at -24dB, with the orange 0dB LED set at 3dB below clipping. The top, red LED displays digital overflow and can therefore light without all the other LEDs becoming illuminated.
11.Output Meters - Displays headroom before limiting occurs. The bottom green LED is set at -24dB, with the orange ‘LIM’ LED set at the limiter threshold for that channel. The top, red LED indicates 4dB of limiting.
12.Mute Keys – One mute key per output channel.
