The features below are only available when using the CT-15X4MA with a CasaTunes music server to control one or more CT-12X8MA and CT-5X4MA matrix amplifiers.
The amplifier has four separate 30W @ 8 Ohms amplified zones.
You can add additional CT-5X4MA and CT-12X8MA matrix amplifiers to expand the number of zones beyond 4.
Alternatively, the CT-5X4MA can also be used to add four zones to an existing CT-12X8MA matrix amplifier.
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 five separate sources.
1 x local RCA source input
1 x Balanced RCA input (using the included BALTX2 adapter)
1 x Balanced Optical source input (using the included BALTX2 adapter)
The BALTX2 adapter allows the 2 connected sources to be located up to 300ft away from the amplifier.
2 x Configurable COAX digital input/output
You can adjust the gain on each source, up to +18dB in 2dB steps, allowing you to adjust and balance the volume level between all the sources
For each zone you can configure up to a 600ms delay for each source.
Each zone sports a 4-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 automatically monitors the temperature and takes progressive action depending on the temperature.
When the temperature reaches:
Each amplifier supports up to 2 keypads. The keypads can be assigned to control any of the zones in the system.
Each keypad includes an IR receiver. For each installed keypad, you can configure whether the IR signal received on a keypad should be forwarded to the IR OUT emitter based on the currently source selected (1-5) for the zone (assigned to the keypad)
After an AC power outage the amplifier restores its settings to the pre-interrupted state. All internal settings are stored in non-volatile memory.
You can backup the amplifier's current configuration settings, and restore them at a later date, if needed.
In addition, you can reset the amplifier to the factory defaults, if needed.
Input sources 2 & 3 provide an analog RCA and digital optical input, respectively, using the included BALTX2 adapter. The BALTX2 adapter provides a balanced connection allowing sources to be located up to 300ft away.
Input source 1 requires an analog RCA connection.
Used to output routed IR from keypads Port 1 & Port 2.
You can configure whether this is an input or output.
When configured as a digital coax input source, this is input source 4.
When configured as a digital coax output, you can assign it to Source 1 or Source 2, or to Zone 1, 2, 3 or 4.
You can configure whether this is an input or output.
When configured as a digital coax input source, this is input source 5.
When configured as a digital coax output, you can assign it to Source 1 or Source 2, or to Zone 1, 2, 3 or 4.
You can connect 1 or 2 keypads to control the CT-5X4MA. You can assign the zone to be controlled by each port. In addition, you can configure the IR Receiver on the keypads to be routed to the IR OUT emitter (based on the currently selected source for the zone)
Network connection
Connection to 15V external power supply (included)
Plug in terminal clamp connectors accepts 16 gauge (1.5mm²) speaker wires
Figure 1 illustrates a possible CasaTunes multi room system configuration where the amplifier is powering audio into three listening zones (Kitchen, Master Bedroom, and Office), and the fourth zone, the Living Room, is being powered by an AV Receiver fed by the pre-amplified output from S5 OUT (which is configured to output Zone 4).
The TV Audio output is being fed into the CT-5X4MA matrix amplifier as S3 (input source 3) using the BALTX2 adapter. The BALTX2 balanced audio adapter allows the source component, TV, to be located up to 300 ft away from the CT-5X4MA matrix amplifier.
Each zone can choose to listen to either of the 2 x CasaTunes music server streams or the TV Audio. In this example, there is one unused input source (S4) which can be connected to other music sources, such as additional CasaTunes music streams (using a CT-Plus-3), Amazon Echo Link, SONOS Port, etc.
Also shown In this example, is how the system is being controlled. You can use an Alexa enabled device and use your voice, you can use Android or iOS phones and/or tablets, and you can also use the optional CasaTunes CT-KP2 keypads.
In larger installations multiple amplifiers can be used together to increase the number of zones. You can add multiple CT-5X4MA amplifiers, or a combination of CT-12X8MA and CT-5X4MA matrix amplifiers, providing greater installation flexibility. For example, you might start with a single CT-5X4MA amplifier, and then decide later to add more rooms by adding another CT-5X4MA.
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-5X4MA 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 CasaTunesXTo configure your CT-5X4MA (and/or CT-12X8MA) 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.
The most commonly used Source Types are:
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 Location setting identifies which source this is. Since you can connect a source to any amplifier, the location setting identifies which 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 is 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:
S4 IN/OUT & S5 IN/OUT connectors can be configured either as input or outputs. To connect these to a secondary power amplifier (such as the CasaTunes CT-250A and CT-2100A stereo amplifiers) or an AV Receiver, configure one or both of these connections as a zone output.
When connecting either of these connections to a coax input on the 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-15X4MA supports up to 2 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-5X4MA 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:
