Your Bluetooth device (Phone, Tablet, etc.) must support the A2DP Bluetooth profile
(commonly known as stereo audio profile) to work with the CA-AMP app. Many of the
latest mobile Phones and Tablets with built-in Bluetooth functionality will support this
profile. For accurate information about your product, please refer to your Bluetooth
device’s user manual for details on the Bluetooth profiles it supports and on how to set
the device’s Bluetooth pairing/searching/setup mode
ABOUT PAIRING
Pairing is the term used when wirelessly connecting two Bluetooth devices for the first
time. This allows the devices to “see” each other and creates a unique lasting connec-
tion between the specific devices.
PAIRING & LINKING YOUR BLUETOOTH DEVICE WITH THE CA AMP APP
1) Make sure your Bluetooth device (Phone or Tablet) is fully charged. Turn it on.
2) Enable Bluetooth functionality on your Bluetooth device. Typically, Bluetooth
controls are found on the device’s tools or settings menu (see your user manual).
Make your device “discoverable”.
3) Power up the DSP125.4D Make sure that the outputs to the amplifier(s) are
disconnected (you can disconnect speakers). At least for the intial setup.
4) Choose “add a new Bluetooth device” or “setup Bluetooth device” on your Phone
or Tablet. It will start to search. If the pairing attempt fails or times out (after 3 minutes),
Power off the DSP125.4D, wait 30 seconds and then power it on again and start
pairing procedure (see steps 2 - 4).
6) After your device and the CA AMP app have discovered each other, a “Pairing
Successful” or similar message should appear on your device and the blue light on the
DSP125.4D will stop blinking and turn solid blue.
7) Pairing remains intact when the DSP125.4D and/or the Bluetooth device is powered off or is
taken out of link range (30 feet). To re-establish an active connection when your Bluetooth
device returns within range,simple turn off and turn on the DSP125.4D.
8) The next time the DSP125.4D is powered on it will automatically try to re-establish a link with
the most recently linked Bluetooth device. If your device does not support auto-linking OR was
not the last linked to the DSP125.4D, you must re-link manually by selecting DSP125.4D from
the Bluetooth device’s menu on your Bluetooth device.
9) MAKE SURE ALL NOTIFICATIONS AND SOUNDS ARE TURNED OFF on you Phone or
Tablet!!! Otherwise during setup if someone texts or calls you..it will scare you how loud it is!!!
So TURN it ALL off.
REMEMBER: From this point on you are in the “CA-AMP” software (APP). Soon you will need
an RTA to REALLY setup your system. Especially the EQUALIZER part of your setup. There
are many available and relativily cheaply.
Our favorite is Audio Tools software (see below) Make sure to buy the APP (Typically $5.00) as
you MUST slow down the RTA for “time Averaging”. We recommend 3s to 6s Decay. You dont
absolutely need an RTA, BUT It makes life much easier and setup much faster. Your call.
(Not my motorcycle..... so I don’t a have “dog in this hunt”! Hey I call ‘em the way I see ’em!!)
BASIC SETUP - START PAGE AND HOME
BEFORE YOU START
Make sure to download the App
for your phone or tablet
First thing to do BEFORE anything is to decide on what system you are building? Good news
is you are using a 4 channel amplifier with a DSP built in and 2 additional “non powered” (pre
amp level) channel outputs.
So you can ONLY do so much! But still quite a bit!. You have to plan you work and work your
plan!!! Trust me it makes it way easier if you have and “end goal” in mind. As mentioned it is
a 4 channel amplifier with 6 channels you can deal with - at least digitally.
SO LETS DECIDE ON WHAT EXACTLY YOU ARE BUILDING - HERE ARE SOME SYSTEM IDEAS TO
LOOK AT. THIS IS PRETTY MUCH EVERYTHING YOU CAN DO WITH THE DSP125.4D
NOTE: BlueTooth functionallity is limited to the SetUp DSP application - CA AMP.
NOT for playing audio!! You’ll need some kind of source unit (like the stock HD HeadUnit)!
