Sources 9-12 can be S/PDIF digital optical inputs using TOSLink connectors, or coax S/PDIF
digital inputs.
When connecting more than one 12X8 matrix amplifier you can physically daisy chain the digital
output sources S1-S12 from the previous amplifier to the digital input sources on the next
amplifier. Alternatively, you can"virtually" connect the sources from the first (master) amplifier to
all other amplifiers using audio-over-IP.
When using a CasaTunes music server, connect the music server streams as follows, depending
on the type of CasaTunes music server:
3
Connect the speaker outputs on the amplifier to your room speakers. You can use up to 14 AWG
wire (although typically 16 AWG is sufficient for most installations). 8-ohm speaker are
recommended, although the amplifier is 4-ohm stable on a maximum of 3 zones. Exceeding this
limitation can cause damage to the amplifier and is not covered by the warranty.
4
Zone outputs 7 & 8 are pre-amplified analog outputs which can be used with a secondary power
amplifier (like the CasaTunes CT-250A/CT-2100A stereo amplifiers), an AV Receiver, or a
powered subwoofer.
Zones 7 & 8 include a Low Pass Filter specifically designed for use with a powered subwoofer.
Use CasaSetup to enable and configure the Low Pass Filter for each zone.
5
The CasaTunes 12X8 Matrix Amplifier supports optional keypads. Connect any keypads to the
amplifier using Cat5e/6 cables terminated with an RJ45 connector. You can connect up to 8
keypads per amplifier. By default the keypad connected to Port 1 controls Zone 1, etc.
You can re-assign the zone to be controlled by a keypad using the amplifier browser utility.
Refer to the CasaTunes 12X8MA manual for more information.

Once you have completed configuring the matrix amplifier connections, power on the matrix
amplifier, then the music server, and complete the software setup.
If you are setting up more than one amplifier, make sure you power each amplifier one at a time.
Start with the Master amplifier (first CT-12X8 amplifier), followed by the additional matrix
amplifiers. Zone numbers are automatically assigned to zones on a matrix amplifier when the
amplifier is first discovered on the network.

Select the "Select Controller" page.
2
Select CasaTunes CT-5X4/CT-12X8 from the list of available controller types.
CasaTunes automatically discovers your CT-12X8 and CT-5X4 Matrix amplifiers in the network.
The amplifiers are also automatically configured the first time they are discovered on the
network. Therefore it is important to make sure you power on the amplifiers starting with the
Master CT-12X8MA amplifier first.
3
If CasaTunes detects more that one amplifier, then select whether to use physical cables to
connect sources between amplifiers, or whether to "virtually" connect sources using audio-over-ip
(the network).
If your setup includes both CasaTunes 12X8 and 5X4 matrix amplifiers we recommend you
select "audio-over-ip". This way, all the sources available on the CT-12X8MA will also be
available on the CT-5X4MA amplifiers.

Return to the Music Server Quickstart Guide to complete the software setup, including configuring the
sources, rooms and music services.
