- Turn the SXD power ON. The startup screen will be displayed (figure 1).
- Press the UP & DOWN buttons to step through the DSP parameters (figure 2).
- Rotate the EDIT knob to adjust settings. A box will flash in the upper right corner when a setting has been changed (figure 3).
- Press the EDIT button to confirm and set the changes. Press any other button to cancel the adjustment.
- Press the BACK button to exit out of a parameter and return to the top level of the menu.
Preset - Choose either Manual Mode, which provides access to the full set of adjustable parameters, or from the four speaker presets: 2 full range, Mono 2-way, Sub/Sat, or 2 subs.
I/O - The I/O screen adjusts the settings for how the inputs will be routed through the DSP to the output connectors.
Stereo: Ch A Input -> Ch A Output & Ch B Input -> Ch B Output
Mono A+B dual: Ch A and Ch B inputs are mixed together, each level control adjusts the corresponding output level
Mono A+B link: Ch A and Ch B inputs are mixed together, Ch A level control adjusts both Ch A and Ch B output levels
Parallel A dual: Ch A input is sent to both Ch A and Ch B outputs, each level control adjust the corresponding output level
Parallel A link: Ch A input is sent to both Ch A and Ch B outputs, CH A level control adjusts the output level for both channels.
Filter (Manual mode) - The filter section allows you to build you own crossover or add speaker protection by stetting the filters to remove the upper and lower limits of the audio bandwidth.
Filter Ch A - Press the Edit button to enter the filter parameters for channel A.
Filter Ch B - Press the Edit button to enter the filter parameters for channel B. If the Ch A filter is On, then the Ch B filter can be set to the same settings by choosing A=B
LPF Freq - Rotate the EDIT knob to adjust the low pass filter frequency.
LPF Slope - Rotate the EDIT knob to adjust the filter type and slope roll off in dB per octave.
HPF Freq - Rotate the EDIT knob to adjust the high pass filter frequency.
HPF Slope - Rotate the EDIT knob to adjust the filter type and slope roll off in dB per octave.
X-Over (speaker preset) - When using a speaker preset, the filters are already configured for a crossover. This allows you to easily set the crossover frequency for your speaker con figuration.
Gain Offset (Manual mode) - This adjustment allows you to set an overall balance between the outputs of the amplifier. This allows you to match the difference of output level of the speakers in a system without needing to constantly adjust the front panel level controls.
EQ - In Manual mode there are three EQ filters per channel. The Low frequency adjustment can be set to a Low Frequency Shelf or to a parametric equalizer (PEQ) with Frequency, Q, and Gain adjustments. The mid band is a parametric equalizer (PEQ) with Frequency, Q, and Gain adjustments. The high frequency band can be set to a High Frequency shelf or to a parametric (PEQ) band. Press the Edit button to enter the EQ parameters. If Ch A EQ is set ON, Ch B can be set to the same settings by choosing A=B. If using a speaker preset, the SXD offers seven EQ preset frequency curves to match your performance setting: DJ, Vocal, Live Sound, Install, Rock, Dance, Jazz.
Limiter - The limiter provides additional protection to your speakers from overload. Press the EDIT button to adjust. The Limiter can be set to -1dB, -3dB, and -9dB.
Delay - The delay time can be used to align speakers in a system. This is useful when using a subwoofer and satellite speaker for front of house to ensure the speakers are in phase for optimal performance. Click the Edit button to adjust. The Delay settings are displayed in milliseconds, inches/feet, and centimeters/meters.
Setup - In the Setup mode the amplifier can be locked and the user can create a four-digit code so settings are not accidentally changed. Click to set Lock Code. Rotate the EDIT knob to adjust the code number, and press the DOWN and UP buttons to move through each digit. Click the EDIT button to set the lock code.
If you have forgotten your Lock Code, you can reset it by turning off the amplifier, then while holding the UP and DOWN buttons turn the power back on.
Factory Reset - This sets all parameters and presets back to the original factory default settings.
