The features below are only available when using the CT-12X8MA with a CasaTunes music server to control one or more CT-12X8MA and CT-5X4MA matrix amplifiers.
The amplifier has six separate amplified zones and two pre-amplified zones. Each zone has controls for bass, treble, balance, loudness, gain, mono and maximum volume limiting.
The two pre-amplified zones include a low pass filter that when selected only passes low frequency audio, ideal for driving Active Subwoofers. When the low pass filter is selected the tone and loudness settings are defeated.
Each zone maybe set to a specific volume level when powered on.
You can have up to 96 zones by adding more CT-12X8 (and CT-5X4MA) matrix amplifiers.
To share sources between amplifiers CasaTunes uses distributed sources, which allows any source connected to any matrix amplifier to be shared with all amplifiers using audio-over-IP.
The amplifier has twelve separate input sources.
Sources 1-8 are either Analog Stereo, or Coax Digital Audio (PCM). Digital Coax has priority if both are connected.
Sources 9-12 are either Coax or Optical Digital Audio (PCM). Only one connection to each source is allowed.
You can adjust the gain on each Analog Source, up to +18dB in 2dB steps.
For each zone you can configure up to a 600ms delay for each source.
Each zone sports a 7-band equalizer.
CasaTunes provides various Equalizer Presets you can select from. These presets are selectable in the Now Playing screen in the CasaTunesX App, and include music presets for Acoustic, Classical, Dance, Electronic, Hip-Hop, Jazz, etc.
The amplifier is controlled, monitored and programmed via Ethernet. In most instances, the CasaTunes music server will be used to control the amplifier.
CasaTunes automatically detects all your matrix amplifiers.
You can use the CasaTunesX App to check for, and update, the firmware on your matrix amplifiers.
The amplifier has 10 buffered IR emitters. Ports 1-8 have IR routing, and are intended to control specific input source components. Two IR ports 9 & 10 are the sum of all IR sources; these control All the zone source components.
There are 8 outputs, one for each zone, on the rear panel of the amplifier labeled AMP ON Control 1, 2, 3, 4, 5, 6, 7, 8. When a zone is powered, the associated output is switched to 12V DC. This can be used to control a secondary amplifier and switch it in & out of standby mode.
The amplifier may be readily set to the default settings. Restoring Defaults clears all memory and resets the zone allocations to zones 1 – 8
After an AC power outage the amplifier restores its settings to the pre-interrupted state. All internal settings are stored in non-volatile memory.
The amplifier automatically monitors the temperature and takes progressive action depending on the temperature.
When the temperature reaches:
The CasaTunesX App will warn the user when the safe operating temperature is exceeded.

Zone 7 & Zone 8 analog audio L/R outputs
Source S1 – S8 analog audio L/R inputs
3.5 mm mono jacks. IR1 thru IR8 are used to control specific source equipment, where each IR port may be assigned to a specific keypad(s). IR9 & IR10 are used to control source equipment common to all zones. These ports output the combined IR1 – IR8 infrared signals
Optical digital source inputs
For connection to keypads
AMPON 1 thru 8 outputs are set to 12VDC when zone is on
12– 24V AC/DC powered doorbell trigger terminals
Figure 1 depicts a typical configuration where the amplifier is providing audio into six of the possible eight listening zones. Only three of the Zones are depicted. Each zone consists of a room with a pair of speakers and a suitable controller. Each zone may be listening to any of the connected sources: CasaTunes music server, Amazon Echo Link, TV, etc
Each zone has a specific control requirement. Choose the controllers that best suit the application.
The CasaTunes CT-KP2 keypad’s may be plugged into any of the eight keypad ports. Source control IR emitters are plugged into the IR Ports. There are ten IR ports: IR1 thru IR8, and IR9 & IR10.
IR1 thru IR8 route source specific IR signals from connected keypads, while IR9 & IR10 output the common IR or the sum of all received IR signals.These Ports may be used for source equipment that is common to all zones.
Speakers in each zone are connected to the amplifier by “Home Run” speaker cables.
The preamplifier output zones are completely independent of the digital amplifier zones. These can be used in locations where a high or lower power amplifier / speaker is required.
A preamplifier zone may be connected to a secondary power amplifier for higher power amplification, or an AV Receiver.
The amplifier has eight stereo RCA audio inputs for connecting source equipment. These source inputs also feature a coax digital input. If a signal is present on the coax digital input it takes precedence over the analog input. There are four additional digital-only source inputs featuring both coax and optical inputs.
A zone may select from any of the connected sources. Someone in the Lounge may be listening to stream 1 from the CasaTunes music server while another in the Study may be listening to music from stream 2 on the CasaTunes music server.
In larger installations, multiple amplifiers can be used together to increase the number of zones (and sources). You can add multiple CT-12X8MA amplifiers, or a combination of CT-12X8MA and CT-5X4MA matrix amplifiers, providing greater installation flexibility. For example, you can use a CT-12X8MA with a CT-5X4MA when you need a 12 zone system.
When using a CasaTunes music server with more than one CT-12X8MA and/or CT-5X4MA amplifiers, CasaTunes uses audio-over-IP and the built-in distributed sources capabilities of the amplifier to virtually connect sources between amplifiers.
To simplify setup in a multiple amplifier setup, CasaTunes implements a Master/Slave model. The master amplifier is the primary amplifier that CasaTunes communicates with (and always includes Zone 1). Slave amplifiers are any additional CT-12X8MA and CT-5X4MA amplifiers on the network.
If one of the matrix amplifiers you are installing is a CT-12X8MA, we recommend you configure this amplifier as your master amplifier. All sources on the master amplifier, that are not hidden, are automatically configured as distributed sources, and are available to all the other matrix amplifiers.
CasaTunes automatically configures any CT-12X8MA and CT-5X4MA matrix amplifiers when discovered on the network. Therefore, it is very important to add the master amplifier to the network first, before any additional amplifiers, otherwise the amplifier selected as the master will be unpredictable.
A major benefit of using audio-over-ip to share sources between amplifiers, is the amplifiers no longer need to be physically located next to each other, as long as they have access to the same network.
If you are using a CasaTunes music server, you must configure the CT-12X8MA using the CasaTunesX App.
You can install the CasaTunesX App on your preferred device, including Amazon, Android, and Apple iOS devices, or you can use any HTML5 browser.Learn more about CasaTunesX
To configure your CT-12X8MA (and/or CT-5X4MA) matrix amplifiers, select the menu option in the CasaTunesX App header and navigate to Settings > System Setup as shown in the figure below.
Navigate to Settings > System Setup > Matrix Amplifier and select CasaTunes CT-5X4/CT-12X8 as the Matrix Model. The selected option is used to setup both the CT-12X8MA and CT-5X4MA matrix amplifiers. To simplify setup, CasaTunes will automatically discover the IP address of your master matrix amplifier.
The Amplifier Interconnect Settings should be configured to use Audio-Over-IP to connect the sources between the amplifiers, when using more than one amplifier.
Navigate to Settings > System Setup > Sources to configure the sources for your matrices. The App displays all the available sources that are available on the first, or master amplifier (see previous discussion about Multiple Amplifiers).
The column on the left is used to display the source number, and whether the source is to be hidden from the UI. Blue items are visible in the UI, gray items are hidden. To hide a source, disable the Display Source checkbox in the Source Settings detail view.
Navigate into a source to configure the source settings. You can configure the Source Name, select the Source Type, whether to Display a Source, and depending on the Source Type selected, there may be additional settings to configure.
The most commonly used Source Types are:
The Location setting identifies which source this is. Since you can connect a source to any amplifier, the location setting identifies the amplifier, and which source on the amplifier, this source is connected to. In the example shown in Figure 4, the David Player source is located on the Amplifier whose ID is 187 and connected to Source 1.
Both the CasaTunes CT-12X8MA and the CT-5X4MA matrix amplifiers support up to 32 distributed sources. Any input source, on any amplifier, can be configured as a distributed source. Distributed sources are shared (virtually connected) with all the other amplifiers via the network using a low latency audio-over-ip protocol.
To add a source that is connected to a slave amplifier:
Navigate to Settings > System Setup > Rooms to configure the rooms for your matrices. The App displays all the available rooms. This includes all the rooms available on all your matrices in your network. In addition, if you enabled SONOS support and/or transmission to AirPlay speakers, then all your SONOS and AirPlay speakers will be listed as well.
Similar to sources, the column on the left is used to display the room number, plus whether the room is to be hidden from the UI. Blue items are visible in the UI, gray items are hidden. To hide a room, disable the Display Room checkbox in the Room Settings Detail view.
To configure a specific room, navigate into the room.
For each matrix amplifier room, you can configure the following settings:
Zones 7 & 8 are two pre-amplified zones that include an optional low pass filter option. You can use one or both of these zones to connect to an Active Subwoofer, an AV Receiver, or you can connect these zones to the CasaTunes CT-250A and
CT-2100A stereo amplifiers to power these rooms.
To support using an Active Subwoofer, the CasaTunesX App provides the option of enabling a low pass filter and configuring the cut off frequency. Please read the blog post, "Adding a Subwoofer to the CasaTunes CT-12X8 Matrix Amplifier", for more information.
When connecting the output of Zone 7 and/or Zone 8 to an AV Receiver, you can configure the receiver model/type to be controlled, whether to use IP or serial control, the parameters for the communication protocol, and to select which AVR input is connected to the output of this zone.
CasaTunes supports many popular AV Receivers, including single or multi-zone receivers, as long as they support IP or serial control. From a user perspective, listening to music in a room that is powered by an AV Receiver is the same as any other room. For more information on seamless AV Receiver integration please refer to the following Tech Note.
Each CasaTunes CT-12X8MA supports up to 8 optional CT-KP2 keypads. Out-of-the-box, each keypad port is assigned to each zone on the matrix amplifier. ie. Keypad port 1 is assigned to the first zone.
You can assign a keypad port to any matrix zone, and you can also configure multiple keypad ports to control the same zone, however, you will need to use the built-in CT-12X8MA web application to re-configure the default settings.
The keypads can be used to control a room, as well as control the CasaTunes media player source, if assigned to the room.
When controlling a CasaTunes media player source, the following functionality is available:
