Generally speaking, a device that runs at a -10dB line level will have outputs or
inputs that are single conductor with a ground, such as RCA jacks, or 1/4”
tip-sleeve phone jacks. Devices that run at a +4dB line level will have outputs or
inputs that are two conductor with a ground, such as XLR or 1/4” tip-ring-sleeve
jacks.
Using Direct Monitoring
When you wish to directly monitor the signal at the inputs of the Quattro, you
may engage the “Direct Monitor” switch for Input 1/2 and/or Input 3/4 by
pressing and locking it to the “in” position. Doing so connects the input (1/2 or
3/4) directly to the corresponding output, bypassing the computer and software.
You may choose to use the Direct Monitoring option to avoid any latency
inherent in your music recording system. Using the ASIO drivers and an ASIO
capable music program with the Quattro will allow you to monitor your
recording source with reduced latency, while using the Sound Manager can
introduce latency that is generally considered unacceptable. The Quattro’s Direct
Monitor option will allow you to monitor your recording source with zero
latency
MIDI Operation
The Quattro provides one (1) MIDI input and one (1) MIDI output. MIDI
operation on the Quattro is independent of the audio operation, and therefore
must be configured separately.
On the Mac, your music software has a MIDI device setup page. Open that page,
and click on the AudioSport Quattro “MIDI In” and “MIDI Out” devices to
select and enable them. As stated, the Quattro can be your only MIDI device, or
it can be used in conjunction with as many other MIDI devices in your system as
your music program allows. Your music software should allow you to arrange the
MIDI ports in a numerical order, according to your preferences.
The diagram below shows a typical MIDI setup involving the AudioSport
Quattro. Shown here is a controller keyboard plugged into the Quattro’s MIDI In
port, and a sound module plugged into the Quattro’s MIDI Out port.
