MULTI-ZONE A/V SYSTEM (Figure 6)

The multi-zone configuration provides automatic power management (system sync) when used with a multi-zone system controller that does not feature intelligent source power management. Some multi-zone controllers come equipped with proper, reliable system sync management capabilities (Xantech MRC44/88). Some provide methods that guess at system status, that is, they will output ON/OFF commands in conjunction with the controller status, but do not really know if the source components are ON or OFF, while others provide no method of power management at all. ISM4 is the perfect complement to these last two types of controllers.

In this configuration, system commands are initiated in the remote zones via keypads and/or IR Receivers. Typically, when the first zone on a multi-zone controller is activated, the controller will turn ON and in most cases, also turn on a Common 12V Control Output. With this Control Out connected to a SMVLT01 Voltage Sensor, the SMVLT01 Voltage Sensor will detect the change of state, (in this case from OFF to ON) and show a control voltage to the Source 1 “Sense In” on the ISM4. (ISM4 System Status is always referenced to the device sensed by the Source 1 “Sense In”.) The ISM4 will then ‘look’ at the other Source Sense Inputs and if they are OFF (no sensor control voltage), the ISM4 will output the Power ON Macros associated with each source to turn them ON.

KEYPADS AND ZONE REMOTES SHOULD BE PROGRAMMED ONLY TO TURN THE LOCAL ZONE ON AND SHOULD NOT INCLUDE SOURCE POWER COMMANDS IN “ON MACROS”. The ISM4 will control the other devices for turn ON. Additionally, each Source Power ON Macro can be programmed for up to five IR commands (and associated delays) so if the sources are to be set to particular settings at turn on these commands will be issued by the ISM4, NOT the multi-zone controller. If at any time that the System Reference Device (multi-zone controller) is ON, any of the other sources turn off, for any reason, the ISM4 will sense the variation from system sync (source OFF vs system ON), and the ISM4 will automatically issue the Power ON Macro for the device out of sync.

In a typical multi-zone system, the connected keypads and/or IR Receivers will issue zone/system commands directly to the system controller (Zone ON/OFF, Volume, Source Select, etc). (The ISM4 does not play any part in controlling the multi-zone controller, only the source components.) Some multi-zone systems issue IR commands for source control from the keypads or pass through IR commands from IR Receivers and zone remotes, while others generate IR commands initiated by keypad button presses or ‘IR trigger commands’. In any case, the IR commands that are output from the controller must be routed from the Common IR Output on the multi-zone controller and then to the IR Control In on the ISM4. The source IR commands will then pass through the ISM4 to the Source IR Outs. This means the IR emitters for the sources will be connected to the ISM4, NOT the multi- zone controller. This allows use of one IR emitter per source rather than having one from the multi-zone controller and one from the ISM4. System operation will be normal and the IR routing will be ‘invisible’ to the user. (This makes the ISM4 a perfect ad-on for exiting systems with sync issues.) One important note: The ISM4 IR pass- through is not routed so systems with multiple same brand/same model devices will not have selective control for tuning SAT 1 or SAT 2 unless multiple IR code groups are available.

Turning the system OFF is the opposite process. Typically, when the last zone on the multi-zone controller is turned OFF the Common 12V Control Out will also turn OFF. The SMVLT01 Voltage Sensor will detect the change of state, (ON to OFF), and cut the control voltage to the Source 1 “Sense In”. The ISM4 will then ‘look’ at the other Source Sense Inputs and if they are ON, (sensor control voltage) the ISM4 will output the Power OFF Macros associated with each source to turn them OFF. KEYPADS AND ZONE REMOTES SHOULD BE PROGRAMMED ONLY TO TURN THE LOCAL ZONE OFF AND SHOULD NOT INCLUDE SOURCE POWER COMMANDS IN OFF MACROS. The ISM4 will control the other devices.

ISM4 specifications

The Xantech ISM4 is an innovative multi-zone audio distribution system designed to enhance the listening experience across various environments. This advanced model is particularly suitable for residential and commercial applications, where high-quality audio distribution is crucial.

One of the standout features of the ISM4 is its ability to manage up to four separate audio zones. This means users can enjoy different audio sources in different areas simultaneously, catering to diverse preferences and activities. The system supports various audio sources, including streaming services, local media players, and traditional radio, which can all be directed to any zone, providing flexibility and convenience.

The ISM4 utilizes sophisticated digital signal processing (DSP) technology to ensure that audio quality is always at its peak. The DSP allows for customizable audio settings such as equalization, volume adjustment, and audio balance, enabling users to tailor their listening experience to their unique preferences and room characteristics. This level of customization ensures that whether it’s background music in a living room or dynamic sound in a home theater, the audio output is optimized.

Another significant characteristic of the Xantech ISM4 is its user-friendly interface. The system can be controlled via a dedicated app or physical switches, offering versatility in how users interact with their audio setup. The app is compatible with both iOS and Android devices, making it accessible to a wide range of users. Furthermore, the ISM4 can be easily integrated with third-party control systems and home automation solutions, allowing for seamless synchronization with other smart home technology.

Connectivity is another strong point of the ISM4. It supports various input options, including HDMI, optical, and analog connections, allowing users to connect a variety of audio sources without hassle.

Reliability and durability are ensured through robust build quality, making the ISM4 suitable for long-term use in various environments. With its combination of advanced audio distribution capabilities, user-friendly features, and robust connectivity, the Xantech ISM4 stands out as a leading choice for those looking to elevate their audio experience in both home and commercial settings. Users can expect exceptional sound quality, seamless integration, and the flexibility to enjoy audio the way they want.
