Introduction How to use this manual As you read this manual, you’ll find figures and diagrams to help you understand and visualise what you’re reading. You’ll also find numerous icons that serve as cues to flag important information or warn you against improper or potentially harmful activities. Icons used include NOTE ! CAUTION “NOTE” identifies an important or useful piece of information relating to the topic under discussion.
Introduction Introducing the SDD3 The SDD3 is a 2 channel full range stereo audio delay line, with one dedicated channel subwoofer delay line. Full range channels are specifically for delaying audio signals for main PA systems or side fills, with a maximum delay time of 393,216ms (approx 134m / 442ft). Each channel is equipped with a tunable high pass filter for easy side fills setup. The full range channels use super digital technology with wide bandwidth and enhanced dynamic range.
Getting started Unpacking Unpack the SDD3 and check to see if there is any damage to it. If you find any damage notify your supplier immediately. Only the consignee may institute a claim with the carrier for any damage incurred during shipping. Be sure to save the carton and all packaging materials for the carrier’s inspection.
Features Front Panel Channel A and B ADC sensitivity For optimal analog to digital converter driving, the full range channels (A and B) are equipped with ADC sensitivity control which increases input level and reduces output level at the same time, so the level pass in the SDD3 does not change when adjustings the ADC sensitivity. The input level can be seen on the level meters. For optimal ADC driving run the level meters so that the signal will exceed 0dB meter level, but never reaches clip level.
Features Front Panel Display Indicates the input levels for each channel separately. Shows the set delays and allows settings of various functions in the menu Function / Exit button Allows the operator to toggle between three main screeens - LEVELS, DELAY, MENU. When you are inside the menu, the button serves as exit. Channel / Next button This button switches between channels, the selected channel is indicated by green LED indicators.
Features Rear Panel POWER CONNECTION Plug power connector For connection to a standard IEC 3-pole AC connector. Before connecting make sure that the mains voltage corresponds to the SDD3's voltage requirements as stated on the unit. Power switch Used to turn the SDD3 on or off. SUBWOOFER CHANNEL CONNECTORS Input Balanced female - XLR connector for connecting the subwoofer signal. The audio input circuit presents a 20kΩ balanced input impedance.
Using the System Delay for additional PA / fill-in delay, with mono cardioid subwoofers in center The main PA works directly, without delay. The left and right channel of the secondary, or side-fill PA works through the full range channels of the SDD3, (channel A and B) for proper time alingment with the main PA. Subwoofers are in the center and work in mono, cardioid mode.
Using the System Delay for main mono PA, delay for additional PA / mono fill-in delay, with stereo cardioid One SDD3 controls one channel of the system, the second channel controls the second SDD3 unit. The main PA works through SDD3 channel A to delay the PA for optimal time alingment with the stage position. The secondary, or side-fill PA works through the full range channel B of SDD3 for proper time alingment with the main PA. Subwoofers work in stereo, cardioid or normal mode.
SDD3 Setup Digital part description The SDD3 has three main display screens for setup and input levels indication. Main screens are: LEVEL for input levels indications, DELAY for delay setup and MENU for attributes settings. For switching between these screens use FUNC/EXIT button.
SDD3 Setup MENU Units mode LEVEL Delay mode Delay can be set in time (miliseconds) or in distance (meters or feets depending on Units setup). When switching between time and distance, the delay time is kept and recalculated to each other. The delay distance depends on the ambient temperature. Units It is possible to switch between metric (meters, °C ) and imperial (feet, °F) units, when switching between each other, the distance is maintained.
SDD3 Setup Subwoofer mode For cardioid setup, you can calculate and set the delay for each subwoofer manually, or you can use cardioid setup in the SDD3 menu. For manual - idependent sub outputs setup, use the normal mode. For cardioid setup use the cardioid mode. When cardioid mode is selected, the subwoofer outputs are linked together with λ/4 distance between front and rear subwoofer outputs.
SDD3 Setup Memory New memory SDD3 is equipped with a dynamic memory list with up to 30 memory positions. New memory can be created when pressing ENTER at New in the memory list. When a new memory is created, it is marked with a position number from 1 to 30 whilst the memory function select is switched to the rename position. Rename memory Memory name can contain up to 8 letters, space or numbers.
SDD3 Setup Lock The SDD3 is equipped with an option to lock the setup of the dital control part. The SDD3 can be locked using four arbitrary capital letters. When the SDD3 unit is locked, it is not possible to change digital parameters. LEVEL meters and delay settings are still visible. Set the Lock password To set the lock password enter the Lock menu, select the Password position and select set at the Lock function list, press ENTER. Set the requested letter by rotating the encoder.
SDD3 Setup Display The SDD3 is equipped with a high-contrast organic LED display. Contrast The contrast of the display can be set in the range from 10% to 100% for comfortable use, depending on ambient lighting. Autodim To ensure long life of the display, the display automatically reduce s the contrast when the unit is not currently used.
