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