PHYSICAL PLACEMENT

It is recommended that you provide at least 6" of free space around the unit for proper ventilation.

Mount the unit on a hard surface with proper ventilation underneath.

Do not stack the VK-300X Integrated Amplifier on top of other units, nor vice versa.

CONNECTING THE VK-300X TO YOUR SYSTEM

Balanced Components

Use balanced XLR interconnects. All input and output connectors are clearly marked on the back
panel.

Note: The VK-300X XLR connectors are wired as follows:

Pin 1: common/shield
Pin 2: positive
Pin 3: negative

Single-Ended Components

Single-ended components have RCA connectors. The VK-300X Integrated Amplifier is
designed to work with a mix of single-ended and balanced components connected to its inputs and
outputs.. If more RCA inputs or outputs are required, then the use of Balanced to RCA adapters is
recommended. These adapters are available from an authorized Balanced Audio Technology dealer
at a nominal charge.

Two types of adapters are available:

Input Adapters: RCA Female to XLR Male

Output Adapters: RCA Female to XLR Female.

Preamplifier Output

These outputs can be used to connect the external power amplifier to the VK-300x.

VK-300X FRONT PANEL CONTROLS

STANDBY Button and LED

The Standby button is used to turn the unit ON and OFF and to switch the Integrated Amplifier into
its Standby mode. The LED indicates the status of the unit’s power circuitry and has four state:

LED OFF Display OFF Unit is in OFF state

Display ON Unit is in ON state

LED Flashing Unit is going through its Power-ON routine

LED ON Unit is in its STANDBY mode

When the unit is plugged into a power line, it will stay in the OFF state until the Standby button is
pushed. The LED will then start blinking and the unit will go through a 50second warm-up
sequence. At the end of that sequence it will turn ON.

Pressing the button again will switch the unit into its Standby mode.

The VK-300X can be turned OFF by pressing and holding the Standby button.

VK-300X Power-On sequence:

When you turn the VK-300X On, it will automatically go through a gentle power-on sequence.
This sequence takes 50 seconds, during which time the display and the Standby LED will be
flashing, indicating the status of the unit.

1. The number on the display during this time indicates the volume setting. This will usually
start at 000. This setting can be changed during this time by using the volume knob or
Volume Up/Down buttons on your VK-R3 remote control transmitter. In addition, such
functions as Phase, Mono, input selection and Mute can be changed during this time either
from front panel or through the remote control.

2. Normally the VK-300X will be not muted (Mute LED on the display is OFF) and will begin
playing at the end of the 50 second delay. If so desired, the unit can be put in the MUTE
mode during this delay interval either by depressing the front panel MUTE switch or by
using the MUTE button on the VK-R3 remote control transmitter.

Turning the VK-300X Off:

The unit can be turned OFF by pressing and holding the Standby button. It will automatically
mute.
