1 Welcome 1.1 Important Safety Instructions Important Safety Instructions: Read these instructions. Keep these instructions. Heed all warnings. Follow all instructions. Do not use this apparatus near water. Clean only with dry cloth. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
1.3 Terminology: Functions, Names & Acronyms. Attenuation/Attenuator: An attenuator is used to reduce the level of an incoming signal. Many think the "volume" control on typical audio equipment makes the power of the amplifier greater. In fact amplifiers are typically pre‐set with a specific amount of gain. The input attenuator or volume control is used to vary the amount of signal that is allowed through to the amplifier's gain section.
Peak: The LED when illuminated indicates a high level signal is present at the device’s input. Caution should be exercised since signals at this level are close to, or are clipping the amplifier. Occasional peaks are acceptable and let the operator know the system noise and headroom are optimal. Constant peak indication should prompt a review of the system and its use demands.

3 Functional Description 3.1 Signal Path + - G + - G 3.2 Analog Section Each analog input circuit employs a fully balanced true differential topology designed to maximize CMRR across all possible input connection methods, where the input and output connectivity has been designed to meet AES48 standards for immunity to hum, buzz and SCIN.
can be routed to any of the 4 (8) analog and 16 CobraNet™ outputs. See Figure 3-1 for details of the internal block diagram. Figure 3-1: Block diagram showing the internal routing of the ION4.4/ION8.8 Both ION4.4 and ION8.8 have simple front panel adjustable phantom power and gain on the mic/line inputs. The rear panel serial (RS485) port is primarily intended for Serial Bridging in Cirrus firmware 2.11.10 and earlier (Contact Cirrus logic for more information).
http://www.CobraNet™.info/en/products • Ethernet port: The Ethernet port provides control & monitoring capability of all DSP and CobraNet™ parameters using a simple TELNET based protocol. In smaller systems, it is likely that the CobraNet™ port will be used for both audio transport and control & monitoring.
Rack Mounting of ION4.4: The MTS ION4.4 is provided with rack mount accessories for either a single ION4.4 with a blank side plate, or as a pair of ION4.4’s in a 1U package. The rack ears are screwed to the side of the ION4.4 for single interface. For two x ION4.4 in 1U, then only the small rack ears are used from each interface (the large rack ears are discarded) and the connecting plate (with the MTS logo) is used to link the front panel of each ION4.4. See Figure 3-2 below. Figure 3-2: ION4.
Figure 3-4: Vertical mounting in riser or cabinet Rack Mounting of ION8.8: The MTS ION 8.8 is built to industry standard 19”/48.25cm, rack mount dimensions, and is 1U – 1.75”/4.45cm in front panel height. Use four screws of appropriate thread pitch and size to your rack. The ION is designed as a single rack height unit using heavy gauge metals for strength.
distribution arrangements are sufficient for the nominal A/C Voltage and the resultant current being sourced by your ION. 3.6 Setup Unpacking your ION: It is recommended that the carton and packing material is retained so the ION may be shipped for service should this be required. Any damage caused by improper packaging will not be covered under warranty.
ground anomalies in large systems where signals may be routed from remote sources with the opportunity for ground anomalies, it is common practice to ‘lift’ the shield on one end (only) of the cable to minimize ground loops. Under any and all circumstances, for safety, check and make sure that proper A/C and systems grounding is practiced. Your MTSI ION is designed in keeping with correct safety grounding approved under international accepted standards.
4 Control Ports 4.1 CobraNet™ The standard CobraNet™ tools, including CobraNet™ Discovery (CNDISCO) and CobraCAD are available for use with the MTS CobraNet™ enabled IONs. These tools are available as a free download from the Cirrus Logic Website. 4.2 Ethernet There is a simple test GUI available for setting up the CobraNet™ port parameters, the ION parameters and controlling the internal DSP. This can be downloaded from the MTS website.
• • • • • • Set the ION Ethernet port to 192.168.192.100 (say). This is done via the VFD – see section below. Go to Control Panel and then open “Network connections”. Click on the General tab and open “Properties”. Select “Internet Protocol (TCP/IP)” and click on properties. Finally, change the selection from “Obtain an IP address automatically” to “Use the following IP address” and set as follows:‐ • IP address: 192.168.192.50 • Subnet mask: 255.255.255.0 It can be any IP address in the range 192.168.
Note: The GUI is common to the MTS amplifier line and there will be many amplifier parameters shown in the screen. However, these will be grayed out and can be ignored. These will not be referred to in the descriptions below. The default page will show 192.168.192.100, as this is the factory IP address set in the GUI. If this is a new ION then simply press “Connect”. Note: Each ION will attempt to obtain an IP address by DHCP on power up. This process lasts about 1 minute.
network configuration. This will have to be loaded manually by the users application software. Note: RS485 settings as follows… • • • Local = Local RS485 control and monitoring of all ION parameters via the CobraNet™ RS485 port (ie serial bridging is off). The Master/Slave toggle then determines whether the ION is slaved to a separate PC/Processor or acting as the master to communicate with wall plates (TBA).
must match the RS485 address used in the GUI/VFD display and the I‐bus baud rate and master/slave setting must match that used in the GUI/VFD display. 4.2.3 CobraNet™ settings The CobraNet™ settings page is shown below in Figure 4-4. One of the key features of the MTS ION is the ability to set up to 4 CobraNet™ audio transmitters and 8 CobraNet™ receivers. In addition, MTS has provided the ability to set each bundle subchannel configuration.
Figure 4-4: CobraNet™ settings page • Receiver setup: This section covers the CobraNet™ receivers. The CS496xxx chipset allows for up to 8 receivers, each of up to 8 channels, subject to an overall channel count of 16 channels.
Note 1: To enter a value in any of the setting boxes, overwrite the existing value and then press “Enter”/”Return”. If “Enter”/”Return” is not pressed then the value is not stored. Note 2: “Update” gets the current values from the ION NOT sends values to the ION.
The router provides the ION with the ability to bridge the analog inputs to the network via the CobraNet™ outputs, as well as route either analog inputs or CobraNet™ inputs to the ION outputs. Figure 4-5: DSP configuration tab.
• Test tone settings: The Test Tone is a simple Sine wave generator with controls for level and frequency (see Figure 4-7 below) Figure 4-7: Test Tone Generator • Ducker: The Ducker allows the user to bring 2 inputs into each channel, one as the BGM source and one as the Paging source. When the paging source input exceeds a set threshold, then the BGM input will be reduced in level set by the depth control.
Figure 4-10: Equalizer Controls • Compressor: The compressor is a simple soft knee device shown in Figure 4-11 below. The threshold sets the level at which the compressor starts operating and the ration sets the amount of compression. Figure 4-11: Compressor Controls There are 8 optional presets, where the power up preset is always configured as Preset 1. If no values are stored in Preset 1, then there will be no power up preset.
• • Note 3: If the ION is in Standby, then the act of recalling a Preset will cause the ION to come out of standby. Note 4: The full preset value load takes around 5 seconds due to the thousands of DSP values that need to be recalled. The “Save to file” process creates a “Preset #”.cfg file that is (by default) stored in the MTS folder in program files (see Figure 4-13 below). The save to file option allows the user to do the following… o Archive all settings.
Figure 4-15: Buttons fade during Save/Recall Process. NOTE: when a preset is recalled from file, the preset is loaded in the selected preset in flash. For example, if the preset menu is set to “1” and preset2.cfg file is recalled, this preset data will be saved in the preset 1 flash location. Therefore, you must set the preset menu number prior to recalling a preset from file, since the recall from file action also stores the recalled preset into flash. 4.2.
