Bluetooth Gadget

1 Welcome! Safety First 2
Welcome to the world of Angry Audio,
home of the audio Gizmos and Gadgets.
A quick peek at the growing catalog of Angry Audio products reveals a pretty
diverse array of Gizmos and Gadgets, but they all have a few things in common.
For starters, each one was created to solve a unique but common challenge in
the studio – one of those niggling annoyances that crop up over and over again
but don’t seem to have a really solid solution. Plus each Gizmo and Gadget
is engineered and manufactured to impeccably high standards and follows
our philosophy that great-sounding audio is made by paying careful attention
throughout the signal path.
The Bluetooth Gadget, which acts as a balanced audio interface between your
smartphone and your audio console and allows you to place any audio from the
phone on the air. This includes regular cellular phone calls or calls made using
Skype or a SIP client, and since the audio is bi-directional, your caller gets a
mixminus feed as well. It can also be used to broadcast an interview recorded
on the phone or even music. It sure beats taping your phone to the mic.
Our promise and guarantee.
We love the Bluetooth Gadget and we think you will too. But we’re also realists
and understand you thought you’d love the Pajama Jeans, Flowbee, and
Neckline Slimmer you ordered on night four of your battle with insomnia. That’s
why we’ll buy back your Gizmo if you change your mind within 30 days.
Plus, every Gizmo and Gadget is warrantied to be free from defects in parts and
workmanship for two full years after you purchase it. If a Gizmo or Gadget fails
within this time period, Angry Audio, at its discretion, will 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 [phone] or reach out to us online via our website at
www.angryaudio.com/contact.
Making a good rst impression.
When you unbox your Bluetooth 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. Behold the durable
powder-coated steel enclosure (oooooh) and the premium components within
(aaaahhh), andleep easy knowing that all of our products are over-engineered
to provide long-term reliability and guaranteed RFI immunity. Even if you can’t
see it, you’ll hear it!
A word or two about safety.
This section used to be eight pages long back in the day when we made the
Angry Lint Fired Clothes Dryer, the Angry Open Door Microwave Oven, the
Angry Gasoline Powered Toaster, the Angry Balsa Wood Ladder, and famously,
the Angry NoGuard™ Deli Meat Slicer.*
And while we’ve since moved on to building audio products, which are
comparatively benign, there are still some things to keep in mind for your safety.
Bluetooth Gadgets 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.
Bluetooth Gadgets have internal 115VAC or 230VAC power supplies.
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 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.
* - We also made the Angry Combination Lawn Mower and Hedge Trimmer but
it never made it to market after some “disappointing” beta testing, so we don’t
talk about it anymore. Ever.

3 The Bluetooth Gadget Explained Front and Rear Panels 4
Why the Bluetooth Gadget?
The ubiquitous smartphone has found its way to the broadcast studio, and
“broadcasting” itself is no longer contained by the concrete-filled, non-parallel,
thoroughly soundproofed walls of a professional studio (that’s how all studios
were built, right?). Trouble is, smartphones were never designed to easily
interface with professional broadcast equipment or even semi-pro podcast
gear.
Enter the Bluetooth Gadget, which uses – ready for it? – a Bluetooth connection
to pair to your Android smartphone or iPhone.
Once paired, it negotiates the optimal codec algorithm (usually APT-X for
Android and AAC for iOS) and connects to your console using analog I/O
on balanced XLR jacks. The sound quality is top-notch, and because the
Bluetooth Gadget is bi-directional, callers are provided with a mix-minus feed.
Most broadcasters will be familiar with the concept of mix-minus, but for our
podcaster friends or live and studio sound engineers, here’s a resource you
may find helpful:
https://thepodcastersstudio.com/how-to-setup-a-mix-minus/.
A front panel 3.5mm (1/8”) TRRS jack facilitates a wired connection from the
phone. See Page 5 for important details about this connection.
A rear panel AES-3 digital output can be used when playing from high fidelity
apps such as your phone’s music player.
Power is provided by an internal 120V or 240V power supply depending on
region and model number.
The Front panel de-mystied.

Power and Console Connections.
Power up your Bluetooth Gadget by plugging it in. The green Power LED will
illuminate. Connect the Left and Right Analog Outputs to a stereo line input on
your mixing console. Connect your console’s mix-minus output to the Analog
Input on the Bluetooth Gadget.
Connecting using Bluetooth.
Briefly push the “BT Pairing” switch to the right and release. A flashing blue LED
indicates the Bluetooth Gadget is in pairing mode. Navigate to the Bluetooth
settings on your phone, enable Bluetooth, then select “ANGRYBT” on the list of
available devices. If no device is paired within 90 seconds, the Gadget will time
out and stop advertising; click “Pair” to re-enable pairing.
Once a connection is established, the Bluetooth light will stay illuminated.
To test the connection, open your phone’s music app and play a song. Best
performance and fidelity will occur with the phone’s volume set at maximum.
If you don’t hear audio, check your console settings and verify that the
”Connection” switch on the Gadget is in the BT position. You may use your
phone as you normally do when it is paired, playing music, voice recordings,
making/receiving phone calls, or using apps such as Skype. The connection
can be terminated on the phone or by briefly pushing the “Pairing” switch on the
Gadget to the left.
Connecting using the front panel jack.
The front panel 3.5mm (1/8”) TRRS jack is connected directly to the rear analog
output jacks to allow the use of a wired connection from the phone. This jack
uses the OMTP standard (Tip = Audio Left, Ring 1 = Audio Right, Ring 2 = Mic,
Sleeve = Ground) which is compatible with most Android devices including
Samsung phones. Phones that use the CTIA standard (Tip = Audio Left, Ring
1 = Audio Right, Ring 2 = Ground, Sleeve = Mic) including iPhones will require
the use of the included adapter.
Using the rear panel digital output.
Audio from apps that provide high-fidelity audio such as your phone’s native
music player can be routed to the digital output. To enable it, reset the Gadget’s
Bluetooth (blue LED off), press and hold the ”Pair” switch for >3 seconds, then
release the switch when the blue LED illuminates. Bluetooth pairing follows the
same process described above. To turn off the digital output, power cycle the
Gadget by unplugging it from the wall then plugging it back in. Note that audio
from phone apps and wired sources will always remain on the analog outputs
only while hi-fi audio will appear only on the AES-3 output when enabled.
Rack mounting your Bluetooth Gadget.
The Bluetooth Gadget sits on four rubber feet that ensure it won’t scratch or
otherwise disfigure the custom Italian marble surfaces prevalent throughout
your palatial studio.
If you prefer to rack mount your Gadget, however, 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.
Power, Connecons, and Pairing Rack Mounng 6
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 your 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 they 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.
