Controls and Functions
The following section details each part of the LIVE series INPUT section including the MIC and LINE inputs,
the two-band EQ, as well as the MIC and LINE LEVEL controls.
1. MIC LEVEL (L612 and L615 only)
The L612 and L615’s MIC LEVEL
controls the overall level of the
microphone input. 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.
2. PEAK LED
The PEAK LED will illuminate
RED when the LIVE series Mic
or Line input is receiving a clipped signal. If the PEAK LED lights up, lower the Mic or Line Level control.
Once the PEAK LED goes off, raise the level controls back up until just before the PEAK LED lights.
3. DYNAMIC PROTECTION
The AMP / CLIP LED is a dual color LED used to monitor the output of the LIVE Series’ 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, 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 LIVE Series’ LINE LEVEL controls the overall level of the LINE input. Raise the LINE Level to adjust the
volume of the signal connected to the LINE input.
Using the Equalizer Section (L612, L612M and L615 only)
The L612, L612M and L615 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. You can set a “music” curve by adding a little boost to both the LOW and HIGH frequency. When
using the L612M as a vocal monitor, try a little cut on the LOW and HIGH frequency to remove unwanted
bass and treble for a more focused mid-range response. For most applications, it’s best to start with the LOW
and HIGH controls set flat (12:00 position) and then use the HIGH and LOW EQ in small amounts until you
reach the sound you want.
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.
6. 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.
