Step 1 - Connect the Main (Game) Audio
As it does for console games, the MixAmp™ will give any
connected PC the benefits of Dolby Surround and high-quality
amplification without using processor cycles or internal
hardware. There are many different ways to connect your
new MixAmp™ -- we’ll list the connections you can use (in the
preferred order of quality).
A) Coaxial Digital - (cable not included) Connecting to the
MixAmp’s™ rear COAX input: this type of connector is very
durable and long runs are reasonably inexpensive. Many PC
motherboards and sound cards come standard with a coaxial
digital output, and we recommend using your MixAmp™ with
this type of input. You may need to adjust your PC’s Audio
Properties, and enable Digital I/O (usually a check box). Consult
your motherboard user’s manual for further information.
B) Toslink Optical Digital - (cable not included) Connecting to
the MixAmp’s™ rear
OPTICAL
input: Many PC motherboards
and sound cards come standard with an optical (Toslink)
digital output. You may need to adjust your PC’s Audio
Properties, and enable Digital output (with XP, this is usually
a check box). Consult your motherboard or soundcard user
manual for further information.
C) RCA Analog
- Connecting to the MixAmp’s™ rear
LEFT/
RIGHT
inputs: use this connection if you don’t have an
available digital connection. The MixAmp™ supports Dolby Pro
Logic II, giving you full surround sound even with an analog
connection. You can use the optional 3.5mm-to-RCA cable to
connect your MixAmp™ to the AUDIO OUT on your PC.
Important: If you connect to an analog 2-channel output on your
PC motherboard or soundcard, you will need to adjust the PC’s
volume control in addition to the MixAmp’s™
MASTER VOLUME
control. Start out with the PC’s volume control at least halfway up.
You may get an unacceptable amount of hum and background
noise if your PC is at or near 100% volume, depending on the
quality of your PC’s audio. Lowering the PC’s volume slider slightly
and raising the MixAmp’s main
VOLUME
level generally works the
best. Try several different settings to find the best sound quality.
