Symbols
+DSP A collection of plug-ins that run on the processor inside our interfaces. There
are over 100 plug-ins in the +DSP package.
+DSP requires a software license to run; it is included with the ULN-8, and
can be added to all other interfaces. The license is added by putting an unlock
code into MIO Console while the interface is connected to the computer.
One license extends to all interfaces connected to the computer; if you move
an unlicensed interface to another computer, it loses the license.
2d Metric Halo's second generation DSP card. The 2d card is part of every new
interface, and is available as an upgrade for older units.

A
ADAT In the context of Metric Halo interfaces, a standard for digitally connecting
two devices together. ADAT sends and receives 8 channels of 24 bit/48k
sample rate audio over one TOSLINK optical cable.
ADC Analog to Digital Converter. The integrated circuit that receives an analog
signal at its input and outputs a digital representation of it.
AES In the context of Metric Halo interfaces, a standard for digitally connecting
two devices together. AES sends and receives two channels of audio per ca-
ble, using 110 Ω cable. A single cable is usually terminated with XLR (or
sometimes BNC) connectors. Multichannel AES devices (such as the LIO-8
and ULN-8) often will use multichannel cables terminated with DB25 con-
nectors.
Attenuate To turn down. Commonly refers to a tool used to lower the output of a device
to make its operating level compatible with another device's input, i.e. an
inline attenuator placed between the output of a 2882 and the input of a
power amplifier.
Aux See Bus
B
Balanced connection A method of connecting audio equipment that is very resistant to electrical
noise. A balanced connector usually has three pins per channel. At the output
the connections are:
• “Hot” or “Plus”: The unmodified signal
• “Cold” or “Minus”: The signal 180° out of phase relative to the original
• Ground
At the input, the “Cold” signal is rotated in phase 180° again and summed
with the “Hot” signal. Any noise picked up in the cable between the devices
