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.

5 Using Your VA-14 4x1 Balanced Audio Mixer

Sections 5.1 and 5.2 describe how to connect and operate your balanced audio mixer, respectively.

5.1 Connecting Your VA-14 4x1 Balanced Audio Mixer

To connect up to four balanced audio sources to the VA-14 4x1 Balanced Audio Mixer unit, as the example in Figure 3 illustrates, do the following:

1. Connect a balanced audio source (for example, a condenser microphone) to the XLR female:

■ INPUT 1 connector
■ INPUT 3 connector

On the underside set the INPUT 1 and INPUT 3:

■ PHANTOM switches to ON
■ LEVEL switches to MIC

1. Connect a balanced audio source (for example, a balanced audio tape player) to XLR female:

2. INPUT 2 connector

3. INPUT 4 connector

On the underside set the INPUT 2 and INPUT 4:

■ PHANTOM switches to OFF
■ LEVEL switches to LINE

1. Connect each of the XLR male OUTPUT 1 and OUTPUT 2 connectors to two power amplifiers, and connect each power amplifier to a pair of speakers.

On the machine underside, set the OUT 1 and OUT 2 switches to LINE.

1. Connect the PHONES OUTPUT connector to a headphone set.
2. Connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity.

For every unused input, be sure to rotate the LEVEL potentiometer fully counter-clockwise (to the minimum level)
