Introduction

The Samson SXD Series stereo power amplifiers have been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by professional front-of-house engineers and installers.

The convenient two rack-space design is compact, and yet there's plenty of power available, with 2 x 450 Watts at 4Ω for the SXD3000, 2 x 750 Watts at 4Ω for the SXD5000, and 2 x 1000 Watts at 4Ω for the SXD7000 over the full frequency spectrum, from 20 Hz to 20 kHz.

The SXD has a full-featured DSP and front panel LCD display with settings for high- and low-pass filters, three-band equalizer, output limiter, delay time for speaker alignment, and digital pass-code security lock to ensure settings are not changed accidentally. There are also four presets designed for typical speaker configurations. These presets will allow you to quickly get up and running with your system by displaying the parameters that are essential to the speaker arrangement.

Input connections are made via both balanced XLR and balanced 14 " TRS connections. For the outputs, the SXD Series provides standard binding posts as well as a Speakon® connectors. To help you set the correct operating levels, the SXD amplifiers include front panel Signal, Output Level, Limiter and Protection LED indicators.

Like all Samson power amplifiers, the SXD Series' internal electronics are based around a serious power-core, with oversized toroidal transformers and large heat sinks. To keep the SXD amplifiers running cool, the design employs forced-air cooling via a temperature-sensitive, variable speed fan, which greatly reduces the chance of thermal and overheating problems. Multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage, assures high reliability under the most demanding situations.

The SXD amps are designed for the rigors of either portable PA system or a fixed installation system with all-steel chassis, 19-inch rack mount design, and convenient carry handles.

Optimized for live sound venues, houses of worship, commercial installations, and for driving live PA systems, the SXD amplifiers will deliver reliable power from gig-to-gig and venue-to-venue. In the following pages, you'll find a detailed description of the many features of the SXD Series power amplifier, as well as a guided tour through its front and rear panels, step-by-step instructions for its setup and use, and full specifications.

We recommend you keep the following records for reference, as well as a copy of your sales receipt.

Getting Started with the SXD Power Amplifier

Setting up your SXD Series is a simple procedure which takes only a few minutes:

Remove all packing materials (save them in case your units needs future service) and decide where the amplifier is to be physically placed—it can be used free-standing or mounted in a standard 19" rack, requiring two rack spaces. When installed, make sure that both the front and rear panels are unobstructed and that there is good ventilation around the entire unit.

CH A RESET CH B - AC INPUT 230V 50/60Cr

Make the speaker connections, using the binding posts, or Speakon® output connectors on the rear panel. It is never a good idea to power up any amplifier that is not connected to loudspeakers.

IN CH A LINK/OUT CH B 1.1

Next, make the signal input connections, using the input connectors on the rear panel (if operating the SXD Series in Ch A Parallel mode, use the Ch A input only). If your mixer has balanced outputs, we recommend the use of three-conductor cabling and connectors.

On the front panel of the SXD Series, turn both Channel level controls fully counterclockwise (to their "MIN" setting). Then connect the supplied heavy-gauge 3-pin "IEC" cable to the rear panel IEC connector and to any grounded AC socket.

Turn the Power switch ON.

Apply an input signal to the SXD Series at or about +4dBu (if sending signal from a mixer, drive the output meters at approximately 0 vu). While the input signal is present, slowly raise the Channel level controls until the desired sound level is achieved. The SIGNAL and Limiter LED indicators next to each Channel input control will show you the continuous power output of the SXD Series as signal is being passed. For the best signal-to-noise ratio, the SXD Series should normally be run with the Channel Input controls at or near maximum (fully clockwise, at the "MAX" position) and the LIMITER segments should light occasionally (but not frequently) during peak levels. If you are using a mixer that has a master output level control, use it to attenuate the signal as necessary to achieve the desired speaker level.

DSP Settings

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 configuration.

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.

Getting Started - DSP

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.
