3 Overview
The VA-14 4x1 Balanced Audio Mixer is a high quality, low noise, 4-input
balanced audio standalone mixer that provides for two different levels on
each input - Mic level or line level, as well as the selection of either a
dynamic or phantom microphone.
The
VA-14 includes:
Four rear panel XLR input connectors and two XLR output connectors
A front panel headphone output, positioned alongside a phones level
potentiometer
Two master front panel potentiometers for adjusting each of the master
outputs of all 1 channels
Four front panel level potentiometers 3 for adjusting each input
A 12 VDC rear panel power socket, which is ideal for field use 2 . The unit
generates broadcast voltage level ±15V and ±48V internally from the
single 12 VDC input
Underside panel switches 3 for selecting the balanced level (Mic or line)
Underside panel switches 3 for applying 48V phantom power 4
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your VA-14 in a
location free from moisture and away from excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit 5 .
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 The combined signals from inputs 1 to 4 are mixed
2 Via a belt battery, for example
3 Each corresponds to its respective input
4 This is for applications that require typical condenser microphones to be connected directly to the VA-14. To prevent
unnecessary damage, apply phantom power to the Mic only when required
