14 ASUS Xonar Essence One

9. Set screws

These 4 screws are used to hold the machine bed (including PCB board and power

module) and machine housing together. For repair’s sake, ASUS technicians may need

a small screwdriver to loosen the 4 screws to remove the front panel and then draw the

machine bed out for checking PCB board (or power module).

1. Unbalanced RCA Output (line-out)

Conventional stereo outputs for connection to the line-level phono/RCA inputs of a

speaker

NOTES:

• Most audio equipment has unbalanced audio inputs and outputs. This means

that the audio output (left, right, or mono) appears on a single wire, and is

referenced to “0V” or “Ground”. Typical connectors used are RCA “phono”

connectors and 1/4” (6.3mm) or 1/8” (3.5mm) jack plugs/ sockets.

• Unbalanced audio works well for short cable runs in low noise environments.

For long distances connection or complex setups where RF noise may be a

problem, Balanced XLR Output is recommended to eliminate unwanted noises.

2. Balanced XLR Output(line-out)

ASUS Xonar Essence One also features true balanced (XLR) outputs. Connect Xonar

Essence One with equipment such as speakers of Balanced XLR connections.

NOTES:

• A lot of professional equipment will have balanced audio inputs and outputs,

usually on 3-pin “XLR” connectors. The line is said to be balanced since the

two signal carrying conductors are of equal (though opposite) potential.

• Balanced XLR Output is a higher quality output that can reject noise and

interference with equipment with balanced inputs, especially perfect for long

cable runs or anywhere that induced noises might be a problem
