Overview
3 Overview
The VA-15xl 6x1 Balanced Audio Mixer is a high-quality, low noise, 6
input balanced audio standalone mixer that provides for 2 different levels on
each input - mic level or line level. The VA-15xl includes a:
• Master front panel level control knob for adjustment of all
channels
• Separate front panel headphone output, positioned alongside a
level control knob for local monitoring of the mixed signal
• 12V DC rear panel power socket, which is ideal for field use
The unit generates broadcast voltage level ±15V and ±48V
internally from the single 12V DC input

.
In particular, the VA-15xl 6x1 Balanced Audio Mixer includes six:
• Front panel level control knobs
3
for adjusting each channel
• Rear panel XLR input connectors and an XLR output connector
• Underside panel switches
3
for selecting the balanced level (mic or
line)
3
• Underside panel switches
for applying 48V phantom power4
To achieve the best performance:
• Use only good quality connection cables
5
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
• Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
VA-15xl away from moisture, excessive sunlight and dust
1 The combined signals from inputs 1 to 6 are mixed
2 Via a belt battery
3 Each corresponds to its respective input
4 This is for applications that require typical condenser microphones to be connected directly to the VA-15xl. To preven t
unnecessary damage, apply phantom power to the Mic only when required
