Introduction 15
Congratulations on purchasing the Samson dB300a active loudspeaker! The dB300a speaker system by Samson takes the concept of powered PA systems to a new level. By combining 300 watts of super clean power, advanced active processing and the highest quality speaker and cabinet components, the dB300a provides studio quality sound for any kind of live sound reinforcement application. The loudspeaker features a super heavy-duty, custom designed, 12-inch low frequency driver and a 1.75 inch titanium diaphragm high frequency driver on a 1" throat, wide dispersion horn. The dB300a offers crystal-clear audio and an ultra-wide sound field. The top end is clear, sweet and articulate. The low-end is enormous. The dB300a is powered by a Class H amplifier that pumps 250 Watts to the low frequency driver and a Class AB amp that provides 50 Watts to the high frequency section—more than enough power to fill any large club. The efficient Class H amplifier design provides the power to deliver transient spikes with incredible punch and sonic purity. The dB300a goes beyond concert-quality to studio-quality thanks to Samson's exclusive Optimax processing. Optimax processing uses sophisticated circuitry to compress and limit output at ideal levels. This allows the dB300a to provide huge volume levels without sacrificing low end. The dB300a offers a practical back-panel, mixer-like preamp section that provides mic and line inputs with individual input level controls. Controls for the selectable low pass filter and extension output selection are also included. The trapezoidal shape of the speaker cabinet offers more than just superior acoustics, not only is it a front-firing PA speaker, the dB300a's are also designed to operate as wedge-style monitors. Adding to the dB300a's practical design is a catalog of mounting options. With the dB300a, setup and break down is quick and easy. The compact cabinet can be easily stacked, using the built-in stacking bumpers or stand mounted using the integral 1 3/8" pole mount receptacle. For permanent installations, the enclosures can be fixed to a wall or ceiling using the optional MB300U U-bracket mounting kit. The dB300a can also be suspended using the four built-in fly points and fixed in arrays using the MB300A array kit. If you are traveling to different venues with your loudspeaker system, the heavy-grade steel grill, scuff-resistant textured finish and rigid corners offer excellent protection against wear and tear on the road. As fixed sound reinforcement or as a durable, great-sounding road PA, the dB300a active monitor is ideal for sound professionals and performers looking for serious power and studio monitor sound quality from a PA speaker system.

Positioning the dB300a
Microphone Positioning - How to Reduce Feedback
Feedback is the annoying howling and squealing that is heard when the microphone gets too close to the speaker and the volume is high. You get feedback when the microphone picks up the amplified signal from the speaker, and then amplifies through the speaker again, and then picks it up again, and so on and so on. In general, it is always recommended that any LIVE mic (a mic that's on) is positioned behind the speaker enclosures. This will give you the best level from your system before feedback. One possible exception is when you are adjusting the sounds of the microphones, since you want to listen in front of the speaker to hear properly. To do this, lower your mixers MAIN VOLUME while setting the EQ and effect from in front of the speakers. Once you have the sound you like, move the microphones to behind the speakers and raise the Main volume.
Speaker Placement
Whenever possible, it is a good idea to raise the speakers above the heads of the listening audience. The dB300a enclosures' feature standard 1 3/8" pole mount receptacles, which are compatible with speaker stands from a variety of manufacturers. In a smaller setting like a school cafeteria, library, or a mall kiosk, you can also use the dB300a in one of the tilt back monitor positions, which will improve the projection of the speakers and may eliminate the need for speaker stands.

The dB300a is an ideal solution for stage monitoring and thanks to its unique design, two wedge monitor positions are possible. When placed on its side, with the high frequency horn facing to the left of the enclosure, the dB300a is tilted at a 30 degree angle, optimizing performance when used on a large stage. When placed on its side with the high frequency horn facing to the right of the enclosure, the dB300a is tilted at a 45 degree angle optimizing performance when used on smaller stages. In a large stage monitor system, several dB300a's can be daisy-chained together using the Line Output. In many instances (when using the dB300a as a monitor system) you may choose to use an external equalizer like the Samson S Curve 131 to increase the volume and reduce the chance of feedback. In this case be sure to set the HIGH and LOW EQ to the 12:00 or flat position.

Operating the dB300a
Controls and Functions
The following section details each part of the dB300a's INPUT section including the MIC and LINE inputs, the two-band EQ, as well as the MIC and LINE LEVEL controls.
MIC LEVEL
The dB300a's MIC LEVEL controls the overall level of the microphone input. The MIC LEVEL control features an audio taper. Raise the MIC Level to adjust the volume of the microphone connected to the MIC input.
IMPORTANT NOTE: Be sure to keep the MIC LEVEL control all the way off if there is no microphone connected.
text_image
SAMSON 1 3 AMP / CLIP MIC LEVEL PROTECTION 2 PEAK MIC INPUT LINE OUTPUT 4 LINE LEVEL LOW HIGH 5 30 6 IN OUT MIX THRU LOW FILTER OUTPUT
PEAK LED
The PEAK LED will illuminate RED when the dB300a's mic input is receiving a clipped signal. If the PEAK LED lights up, lower the MIC LEVEL control. Once the PEAK LED goes off, raise the level controls back up until just before the PEAK LED lights.
DYNAMIC PROTECTION
The AMP / CLIP LED is a dual color LED used to monitor the output of the dB300a's internal power amplifiers. When the unit is first powered on, the AMP / CLIP LED will light red (indicating the output relay is open). After the soft-start circuitry activates and the output relay closes, the AMP / CLIP will change to bright green indicating the unit is ready for operation. The LED will flash red on signal power peaks, while the green LED is still on. If there is a failure condition such as DC on the output, the output relay opens and the LED will switch to solid red, indicating a fault. If this happens, contact your authorized Samson Audio Service Center.
LINE LEVEL
The dB300a's LINE LEVEL controls the overall level of the LINE input and features an audio taper. Raise the LINE Level to adjust the volume of the signal connected to the LINE input.
Using the Equalizer Section
The dB300a input channels feature a 2-band equalizer allowing you to adjust the high and low frequencies independently. The channel's frequency response is flat when the knobs are in the "12:00" position.
LOW
Rotating the LOW knob towards the right will boost the bass frequencies at 100Hz by 12dB, and rotating it towards the left will cut the bass frequencies at 100Hz by 12dB.
HIGH
Rotating the HIGH knob towards the right will boost the treble frequencies at 10kHz by 12dB, and rotating it towards the left will cut the treble frequencies at 10kHz by 12dB.
Operating the dB300a
Controls and Functions - continued
LOW FILTER
The dB300a also incorporates a Low-cut FILTER which when engaged, will roll off the low frequency response of the cabinet beginning at 80Hz. The low cut FILTER is two pole, which means that the low frequency roll off will gradually cut more and more of the low frequencies (12dB per octave). When you press the FILTER switch in, the green LED will illuminate indicating that the Low-cut FILTER is engaged.

SAMSON dB300a MIC LEVEL AMP / CLIP PROTECTION LINE LEVEL LOW HIGH PEAK MIC INPUT LINE OUTPUT LINE INPUT IN MIX OUT THRU LOW FILTER OUTPUT 9 10 11The Output switch is used to select
the signal that is sent to the Line Output. You can have either a parallel output directly from the Line input, or a mixed signal including the Mic and line inputs plus the EQ and limiter. When the switch is in the up position, the signal on the Line Output is exactly the same as the signal on the Line Input. When the switch is in the down position, the Line Output carries the MIX of the Mic and Line Inputs. If the Level controls, High and Low Equalizer and Filter are used, they will also affect the signal sent to the Line Output.
Input and Output Connectors
MIC XLR Input
The dB300a's microphone input accepts a standard low impedance (150-600 Ohms) input and the connection is made via a standard female XLR connector. The microphone input features a high quality, discrete transistor pre-amp providing transparency and extended dynamic range. The MIC input can work simultaneously with the LINE input so it is possible to use a microphone while playing alone with a keyboard that is plugged into the dB300a's LINE input. You can control the microphone input by using the MIC LEVEL control as described in the section below.
LINE OUTPUT
You can run several monitors by using the LINE OUTPUT to daisy-chain one dB300a to another. The LINE OUTPUT is a balanced output that, depending on the position of the OUTPUT switch, will have either a direct parallel output of the Line input, or the Mix of the Line and Mic input. For more information on the Output switch, see section 8 above. For more information on cables and wiring, see page 14 of this manual for a detailed wiring diagrams.
LINE Combo Balanced Input
For added convenience, the dB300a employs a Combo connector that accepts a standard XLR mic cable for balanced line level signals, or a standard 1/4" instrument cable for either balanced (TRS - TIP/RING/SLEEVE) or unbalanced (TS - TIP/SLEEVE) line level signals. The LINE input can work simultaneously with the Mic input so it is possible to use a microphone while playing alone with a keyboard that is plugged into the dB300a's LINE input. You can control the LINE input by using the LINE LEVEL control as described in the previous page. For more information on cable and wiring, see page 14 of this manual for a detailed wiring diagrams
Setting Up Your dB300a System
Using Speaker Stands
The dB300a enclosure features a standard 1 3/8", pole mount receptacle, which is compatible with speaker stands from a variety of manufacturers. Before installing the dB300a on a speaker stand, loosen the thumbscrew located on the bottom of the rear side of the enclosure. Once installed on the stand, be sure to tighten the thumbscrew to hold the speaker in place. Be careful not to over tighten the thumbscrew to avoid stripping the threads.
Stacking the dB300a
The dB300a enclosure incorporates gender mating stack feet and bumpers that allows you to stack one dB300a on top of another. When stacking the dB300a's, be certain that the rubber feet from the top unit are securely fastened into the bottom unit's stacking bumpers.
NOTE: DO NOT STACK dB300a's OVER TWO (2) TALL.

This example shows a typical PA system using mixer with a pair of dB300a's for the main left and right mix. A separate signal from the mixer's AUX/MONITOR bus is sent to two additional dB300a's placed in the tilt-back, wedge positions for use as floor monitors. In order to increase the output of the monitor system, the use of an external graphic equalizer like one of the Samson "D Class" or "S curve" series is highly recommended.
