Overview
3 Overview
The VA-15xl6x1 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-15xl6x1 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
