A U D I O P H I L L E O 1 & 2 U S E R M A N U A L

 One infrared remote receiver cable with 2.5mm audio connector

 One 3.5mm stereo audio to dual mono adapter for 12V trigger outputs

(option)

Getting Started

There is no need for installations or configuration on supported operating systems

(Linux, OSX, and Windows XP/Vista/7, iPad). Just plug it in and the default USB

audio operating system drivers should install automatically.

Note that under XP, Linux and OSX sample rates of 44.1, 48, 88.2, 96, 176.4 and 192

are available by default. Under Windows Vista/7 sample rates of 176.4 and 192 are

only available with our custom driver. Also note that only bit depths of 24 are

available. SPDIF is effectively always 24 bits. 16 bit audio simply only uses the upper

16 of those 24 bits. 44/16 and 48/16 are supported because this is required by the

iPad.

Note: The Audiophilleo1 acts like a multimedia keyboard so that it can send

play/pause/next/previous commands to the computer just like a keyboard would.

Since OS X thinks the Audiophilleo1 is a keyboard and audio device, it will ask you to

press keys on the keyboard in order to identify the keyboard layout. You can press

these keyboard keys in the Audiophilleo1 “settings->keyboard” menu. After this, the

identify window will never come back.

Connections

Figure 1 shows how to connect the Audiophilleo1. The Audiophilleo2 is identical

except that it misses the OLED display, joystick, 12V power supply input, 12V Trigger

outputs, and infrared remote receiver input.

Note: If your Audiophilleo1 or 2 comes with the PurePower option it will have an

additional power connector (see Figure 1). The PurePower must be connected and

providing power to this connector or there will be no sound. Also, after threading the

power cable into the Audiophilleo1/2, it is necessary to fully push it in. This will give

solid electrical connection.

Note: Please do not plug in or unplug the 12V power supply, 3.5mm stereo adapter,

or infrared remote receiver while the Audiophilleo1 is powered up.
