ISP Technologies VMAX 150C - Manual (Page 5)

4. MIC/LINE1 BALANCED XLR INPUT-This female XLR connector provides the input for
channel 1.
5. LINE3 GAIN CONTROL- This control determines the gain of the MIC/LINE channel 1.
When using this input for a line level input, the gain should be set a minimum. The
Microphone preamp provides up to 50db of gain.
6. LINE3 BALANCED XLR INPUT-This female XLR connector provides the input for channel
3.
7. MIC/LINE2 GAIN- This control determines the gain of the MIC/LINE channel 1. When
using this input for a line level input, the gain should be set a minimum. The Microphone
preamp provides up to 50db of gain.
8. MIC/LINE2 BALANCED XLR INPUT-This female XLR connector provides the input for
channel 2.
9. POWER LED –When lit this LED indicates that the VMAX power is on.
10. LIMIT LED – This LED lights when the internal limiter is active. This LED will flash when
the signal level at the input of the power amplifier is at maximum i.e. where the power
amplifiers will start to clip. When the input to the amplifier reaches the point where the
limiter becomes active, any increase in input level will be limited at the input to the power
amplifiers. This will allow the VMAX to play at maximum level but not allow the speaker
produce large amounts of distortion.
11. SIGNAL LED – This LED lights when the input signal exceeds –25dbu.
12. LINK OUTPUT CONNECTOR- This output provides a line level output signal that can link
two VMAX cabinets together. Two VMAX speaker cabinets can be linked together allowing
both VMAX speakers microphone preamps to sum together and feed both VMAX speakers
power amplifiers in mono. By connecting a cable with two female XLR connectors from the
link output of one cabinet to the link output of the second cabinet all four microphone
preamps will sum together and feed both VMAX speaker cabinets.
LINK / MICROPHONE SUM CONFIGURATON
In the configuration above, you can still use Line3 inputs as stereo inputs if desired.
