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.
1
MIC LEVEL
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.
2
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 autho-
rized Samson Audio Service Center.
4
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.
5
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.
6
HIGH
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.
