Failsafe Gadget
1 Welcome! Safety First 2
Welcome to the world of Angry Audio,
home of the audio gadgets.
The audio world is filled with complex, high-tech gear. Much of it bristles with
seductive shapes and eye-catching lights and displays, and all of it promises to
make things sound better and open up new creative possibilities.
But in order for those products to shine, you still have to get the basics right and
sweat the details. Good audio isn’t made by one component. It’s made by getting
things right every step of the way, especially the little things.
Accordingly, every audio gadget – including the Failsafe Gadget – is designed
to solve common yet critical problems, and are meticulously engineered with
performance and longevity in mind to deliver pristine audio for many years.
Our promise and guarantee.
We know you’ll love your Failsafe Gadget, but the universe is a strange place, so
it’s always possible that you won’t. That’s why we give you 30 days to bond with
your gadget. If the two of you can’t get your chakras to align, we’ll buy it back.
Plus, every gadget is warrantied to be free from defects in parts and workmanship
for two full years after you purchase it. If a gadget fails within this time period,
Angry Audio will, at its discretion, repair or replace it so long as you let us know
of the failure within the warranty period and can provide proof of purchase in the
form of a dated sales receipt. You can call us at +1 615-763-3033, or reach us
online at at www.angryaudio.com/contact.
Making a good rst impression.
When you unbox your Failsafe Gadget, we really hope it makes a good first
impression and that you take a moment to appreciate the lengths we’ve gone
to in order to create a “built for broadcast” product. All audio gadgets are over-
engineered to provide long-term reliability and guaranteed RFI immunity.
Some of this is apparent - such as the rugged powder-coated steel chassis - but
much of this goodness is invisible, like the premium components used in the
audio path. Even if you can’t see it, you’ll hear it!
A word or two about safety.
Most of this falls under the category of common sense, but the company
lawyers started to visibly twitch when we suggested we didn’t need to spell out
the obvious. Besides, extensive testing with volunteer focus groups resulted in
over 100% of the participants who got a user guide without safety instructions
immediately plugging in the device and jumping recklessly into their (filled)
bathtubs. After a few weeks of this, we grew concerned our customer base was
eroding, so safety warnings it is.
Audio gadgets aren’t meat slicers or TIG welders, but still, they are intended to be
used by qualified personnel only. To avoid electric shock, do not open the unit or
attempt to perform any servicing unless you are qualified to do so.
The Failsafe Gadget has internal 120VAC or 240VAC power supply. Hazardous
voltages are present whenever the unit is plugged in and may still be present on
certain components even when the unit is unplugged.
The power cord is the primary disconnect device and so the outlet providing
power to the gadget should be easily accessible. In other words, make sure you
can back out of making any bad electrical decisions by yanking the plug. Use
only a properly grounded outlet for power. Do not cut the ground pin or use a
ground-lifting adapter, and do not defeat the polarized plug. Do not overload
outlets.
Do not expose your gadget to rain or moisture. Do not block any ventilation
openings, as lack of airflow could damage the unit or create a fire hazard.
Any electronic device can fail without warning; do not use this product in
applications where a life threatening condition could result due to failure.
Do not buy candy for trick-or-treat that you yourself will not eat. Do not start saying
things like, “When I was a kid…” – it’s a slippery slope to Curmudgeon Town. Do
not wear a black belt with blue polyester slacks – this is white-belt-only territory.
3 Rack Mounng Wall Mounng 4
Mounting your Failsafe Gadget in a rack.
The Failsafe Gadget sits on four rubber feet that ensure it won’t scratch the zebra
wood inlays on your antique mahogany desk.
If you prefer to rack mount your gadgets, you’ll need the optional Rack Mount kit
which allows one or two gadgets to be installed side by side in a standard 1RU
rack space.
Each Rack Mount Kit consists of a custom rack panel with cut outs for all front
panel controls and displays. A blank filler panel is also provided if you are
mounting only one gadget.
When rack mounting, remove the four rubber feet (“A”) from the bottom of the
gadget with a #1 Phillips screwdriver.
Remove the four front panel 3/32” hex screws (“B”). You can rummage around
your toolbox for your own hex key, or use the one we thoughtfully provide in the
mounting kit.
Line up the gadget so that the holes
exposed after removing the socket
head screws line up with the mounting
holes (“C”) in the rack panel.
Attach the rack panel to the front of
your gadget with the same screws you
just removed. If you dropped one and
it immediately rolled to an inaccessible
location (as these things always do),
don’t panic – we’ve included spares in
the kit.
Finally, use the provided rack screws
(all four, please) to mount your gadgets.
Attaching your Failsafe Gadget to a wall.
If you prefer to secure your gadget to the inside of a rack, cabinet, or other flat
surface, the optional Wall Mount kit comes in handy.
Each Wall Mount Kit includes two brackets, four No. 6 screws, and four cup
washers.
Remove the four rubber feet (“A”) from the bottom of the gadget with a #1 Phillips
screwdriver, being careful to save the screws.
Align the bracket holes with
the holes in the bottom of the
gadget, then attach the brackets
using the screws removed from
the rubber feet.
Use the four No. 6 screws
(“B”) and the four cup washers
(“C”) to secure the gadget to a
plywood surface. Drilling pilot
holes is recommended to reduce
the risk of splitting the wood.
Different hardware (not supplied)
will be required if you are
mounting the gadget to a drywall
(or other) surface.

5 Under Counter Mounng Desktop Mounng 6
Mounting your Failsafe Gadget under a counter.
Your Failsafe Gadget can be mounted under a counter, desk, or table using the
optional Under Counter Mount Kit.
This kit includes two brackets, four No. 6 wood screws, and four cup washers
suitable for mounting to a plywood surface. Different hardware (not supplied) may
be needed if the mounting surface is a different material.
Remove the four rubber feet (”A”) from the bottom of the gadget using a #1
Phillips screwdriver, being careful to save the screws.
Line up the brackets (“C”) so that their
mounting holes line up with holes exposed
after removing the rubber feet. Orient the
brackets as shown in the diagram to the right
so that the deeper flat side supports the gadget
and the “notched” side faces the
under-mount surface.
Use the panhead screws (“B”) removed from
the rubber feet to secure the brackets to the
gadget.
Use the four provided No. 6 screws
(“D”) and the four cup washers (“E”)
as shown in the diagram to the left
to secure the gadget to the plywood
underside of the counter, desk, or
table.
Drilling pilot holes is recommended
to reduce the risk of splitting the
wood.
Using your Failsafe Gadget on a desktop.
If you like the idea of using the Failsafe Gadget on a desktop but prefer a more
permanent installation along with the convenience of having it angled up toward
the user, we’ve got you covered with the optional Desktop Bracket Kit.
This kit includes two brackets, four No. 6 wood screws, and four cup washers
suitable for mounting to a plywood surface. Different hardware (not supplied) may
be needed if the mounting surface is a different material.
Remove the four rubber feet (“A”) from the bottom of the gadget using a #1
Phillips screwdriver, being careful to save the screws.
With the bottom of the gadget facing
up and the front panel facing toward
you, line up bracket “C” with the holes
exposed after removing the feet on
the right side of the gadget. Orient the
bracket as shown in the diagram to the
right so that the flat side is attached to
the gadget, and the “notched” side sticks
up with the notch facing outwards. Use
the panhead screws (“B”) removed from
the rubber feet to secure the brackets to the gadget.
Use the four provided No. 6 screws (“E”)
and cup washers (“F”) as shown in the
diagram above to secure the gadget to a
plywood surface.
Drilling pilot holes is recommended to
reduce the risk of splitting the wood.

7 The Failsafe Gadget Explained A Typical Applicaon 8
The most dreaded words in radio...
There are a host of things that can induce panic at a radio station. A dip in the
ratings. The espresso machine in the break room taking a dirt nap. Someone from
sales driving the engineering van. A promotions event involving a helicopter and
turkeys. But none quite as chilling as the words “Dead Air.”
Dead air can result from malfunctioning equipment to air talent getting locked out
of the building after a botched attempt at a convenience store run. Regardless,
dead air almost always occurs in the dead of night, and we thought it would be
nice to have a way to deal with these off-air emergencies without being dragged
out of a warm bed. Enter the Failsafe Gadget.
t
At its core, the Failsafe Gadget is a stereo A/B switch - but with an important twist.
When it detects silence on its primary input, it automagically feeds its output with
audio from a secondary input such as a looping CD player, a portable music
player, or a backup automation computer. You decide what threshold constitutes
silence, how long the gadget waits before switching sources, and whether or not
it switches back to the primary source by itself when audio is restored. It can even
start the backup audio source or trigger an alarm when silence is detected.
In the event of a power failure, a relay bypass circuit routes the backup audio to
the output (as a loss of power to the Failsafe Gadget likely means a loss of power
to the main audio source). Be sure your backup source is fed from a UPS or a
different circuit to take advantage of this feature.
Alternatively, you get set up the Failsafe Gadget so that the presence of a signal
(rather than the absence of one) sets things into motion by feeding the primary
audio into the B input and routing the override audio into the A input. When audio
appears on the (normally quiet) A side, it interrupts the B side audio. When the A
side goes quiet, the B side once again feeds the output. This can be useful for
inserting emergency audio or for interrupting regular programming from a remote
event during unattended operation.
Of course, you can bypass the sensor and manually switch between two audio
sources for programs that only need automatic switching during unattended
segments with either the front panel buttons or remotely using the logic port.

Connecting to the outside world.
The 9-pin DSUB connector on the rear panel of the Failsafe Gadget serves as
a handy logic port for manually switching between the A and B audio sources
remotely, and for starting the the backup audio source or triggering a silence
alert.
The pin-outs are as follows:
1: Common 6: Relay B
2: Remote A (Main Source) 7: Relay C
3: Remote B (Backup Source) 8: Relay A
4: No connection 9: Common
5: No connection
A (MAIN)
B (BACKUP)

B (NC)
A (NO) C
A momentary contact closure to ground via a pushbutton can remotely switch
between the A and B sources, which exactly mimics the front panel buttons. To
select A, short Pin 2 to Pin 1. To select B, short Pin 3 to Pin 1. An open collector to
ground or relay contact to ground will also activate these inputs.
Dry relay contacts provide A/B switch status. If source A is active, Pin 8 will be
shorted to Pin 7. If source B is active, Pin 6 will be shorted to Pin 7. Please note
this relay is intended to switch small logic signals; never connect the logic port to
AC mains power.
If soldering or crimping pins for a DSUB connector makes you nervous or sad,
we’ve included a DB9M to RJ45F adapter in the box for the convenience of wiring
with CAT5/6 cable. Happy now?
