INTRODUCTION
Thank you for purchasing Costling Audio RIO A2 Direct Box. The Costling Audio RIO
A2 Direct Box is a professional Direct Injection Box.
DI stands for " Direct Injection" and DI Boxes are also called Direct Boxes. You need to
use Direct Boxes if you wish to convert a high impedance instrument signal or an
unbalanced signal into a format that will be suitable for direct conn-ection into a mixer.
With the Costling Audio RIO A2 Direct Box:
a.You can convert a high impedance signal into a low impedance signal.
b.You can convert an unbalanced signal into a balanced signal.
c.You can convert a line level signal into a microphone level signal for connection Into
the Microphone input of the mixer.
d.You can isolate the instrument on stage from the mixer. In such way you can
Eliminate noise caused by the ground loop.
There are basically two different kinds of Direct Box on the market: Passive and active.
Both will be connected to the MIC input of the Mixer but active boxes such as your RIO
A2 Direct Box perform better and produce better frequency res-ponse. Enjoy your
Costling Audio RIO A2 Direct Box and make sure to read this Manual care-fully before
operation!
FEATURES
● XLR input and output connectors.
● Converts unbalanced input into balanced output.
● Phase problems instantly corrected through PHASE INVERSION switch.
● Ground loop problems eliminated via GND LIFT switch.
● 8kHz High cut Filter available for guitar applications.
● 1 CHANNEL Direct Box for applications in recording studio and stage.
● Special transformer decoupling in order to avoid hum and noise pick-up.
● Outstanding audio performances insured by ultra-low noise operational amplifiers.

CONTROL ELEMENTS
Front Panel
1. Ba
ttery Power Switch
This push-button will activate the power supplied by the internal 9 Volt Batte-ry (not
supplied). The (2) Led will blink at several seconds intervals. If you are using your RIO
A2 Direct Box with external phantom power you can release the switch in order to
preserve the battery life.
2. P
ower LED
When operating with phantom power, this LED will light up continuously. If you are
using the internal 9 Volt battery, the LED will blink at several seconds intervals.
3. 20dB Attenua
tion Switches on input
Press either of these switches and you will attenuate the input signal by 20dB. In such
way you can produce increased headroom and reduce the risk of distortion because of
level peaks at input level when the input signal is quite hot.
4. Phase In
version Switch
By pressing this switch you will reverse the signal phase by 180˚. In normal situations,
just forget about this switch but in case of inversion of the connectors this switch
becomes very useful to compensate the phase cancellation
5. GND Lift Switch
This
switch disconnects the input signal ground from the output signal ground. In this
way you can avoid hum produced by ground loop.
6. High fr
equency Filter at 8 kHz
You can press this switch and activate the 8 kHz High Cut Filter when using an electric
guitar with your RIO A2 Direct Box.

Finally
, the output signal at MIC level will be produced by this XLR output co-nnector.
You must pay particular attention to the wiring of this XLR connec-tor if phantom power

APPLICATION
So, we are telling you that after you have spent a fortune for your gear, you still need
to buy an extra piece of equipment such as the RIO A2 Direct Box. You will be amazed
how the RIO A2 Direct Box will transform your audio system whatever for studio or for
live applications: No risk of miss-match impedance, no ground loop and hum. Please
look at the following examples of applications.
1. W
hen the input signal is a Bass Guitar
You can connect your bass guitar directly into your RIO A2 Direct Box. Then you can
connect the RIO A2 Direct Box into the MIC input of your mixer. In such a way, you do
not need a Bass Amplifier on stage but you can still feed a Bass Amp using the Link
Output connector of your RIO A2 Direct Box.
2. W
hen the input signal is a microphone
In this way the unbalanced output of a microphone is converted into a balanced one.
In such way you can cover a longer distance from the microphone to the mixer still
avoiding noise problems.

APPLICATION
3. How to convert a strong signal into MIC level signal
If you connect a line level signal or a speaker signal into a MIC input you would
create a disaster. To avoid this just use either or both the 20dB attenuation
switches on your RIO A2 Direct Box.
4. Ho
w to isolate the instrument on stage from the mixing console
Tricky stuffs now from your RIO A2 Direct Box OK in order to avoid ground problem,
the
ground connection of an instrument to the mixer should be made with the RIO A2
Direct Box. But in some case the instrument will be connected to an amplifier as well
through the same RIO A2 Direct Box, so you have now a grounding point with the
amplifier and another one with the mixer. If small differences occur in the ground of the
amplifier and the mixer, AC current will flow into the shield. The resulting "ground loop"
and 50/60 Hz noise will radiate from the shield to the center conductor and will produce
hum. Fortunately, your RIO A2 Direct Box is equipped with a GND Lift Switch that will
eliminate the interference cause by the ground loop.
