Controls and Functions
The following section details each part of the dB500a'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 dB500a'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.
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 dB500a'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 dB500a'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.
4
LINE LEVEL
The dB500a'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 dB500a 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 rotating it
towards the left will cut the bass frequencies at 100Hz by 12dB.
HIGH
6
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.
