Samson db300a User Manual

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. 

 

 The dB300a’s MIC LEVEL controls 

the overall level of the micro-

phone input.  The MIC LEVEL 

control features an audio taper. 

Raise the MIC Level to adjust the 

volume of the microphone con-

nected to the MIC input.

IMPORTANT NOTE: Be sure to keep 

the MIC LEVEL control all the way off if 

there is no microphone connected. 

 

 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.

 

 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 autho-

rized Samson Audio Service Center.

 

 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.

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 rotat-

ing it towards the left will cut the bass frequencies at 100Hz by 12dB.

 

 

 Rotating the HIGH knob towards the right will boost the treble frequencies at 10kHz by 12dB, and rotat-

ing it towards the left will cut the treble frequencies at 10kHz  by 12dB.
