Introduction About the documentation This manual mainly explains operation and specifications for the TX6n, TX5n, and TX4n (subsequently referred to as TXn) power amplifiers. When using the TXn, you will also need to consult various manuals other than this document. ● Manuals other than this document TX6n/5n/4n Owner’s Manual (printed) Explains mainly the initial setup. Amp Editor Installation Guide (PDF) Explains the installation procedure for Amp Editor and the uninstallation procedure.
Introduction Terms This section explains terminology specific to the TXn. ■ Amp Editor This is computer application software. This software allows you to monitor and control the TXn amplifiers from your computer. ■ Scene Settings such as power-on/standby or mute for each amplifier are called a “scene.” By recalling a scene, the saved settings can be immediately applied to the amplifiers. Each TXn unit has 50 scenes.

Panel Operations Initializing the internal memory Here’s how to initialize the amplifier’s internal memory. As desired, you can initialize two types of data. • User Data : All user data except for the event log and the Speaker Processor library will be initialized. • Library : Only the Speaker Processor library will be initialized. • When you initialize the internal memory, the settings that had been saved in internal memory up to that point will be lost. Use caution when performing the following steps.
System Connection Examples Daisy-chain connection via analog or digital audio Here is an example of multiple amplifiers connected in a daisy-chain via analog audio signals or digital audio signals (e.g., AES/EBU). In the case of analog connection, daisy-chain the [THRU] jack and [IN] jack. In the case of digital connection (the standard AES-IO card), daisy-chain the [THRU] jack and [IN] jack, or the [OUT] jack and [IN] jack.
System Connection Examples ■ Thru-output for digital connections For digital connections (the standard AES-IO card), the “thru” output from the [IN] jack to the [THRU] jack will be a signal that has passed through the buffer if the power is on, or a signal that bypasses the buffer if the power is off. DIGITAL (AES/EBU) IN THRU Relay Relay Buffer If the power is on, the signal is regenerated in the buffer, theoretically allowing daisy-chain connection of any number of units.
System Connection Examples Redundant connections (Backup) By connecting both the analog audio signal and the digital audio signal, you can make a redundant connection (duplicate audio connections). If the digital audio signal is interrupted by a problem such as a broken connection, the system will switch to the analog audio signal.
System Connection Examples EtherSound connections You can use an interface card such as the MY16-ES64 to send and receive audio signals via an EtherSound network. From a single computer, you can use Amp Editor to monitor and control the amplifiers and use AVS-ESMonitor to make EtherSound settings. However on the amplifiers, the amplifier control connections and EtherSound network connections are separate. NOTE • You can connect up to three MY16-EX I/O expansion cards to a single MY16-ES64 card.
System Connection Examples Bridge connections from EtherSound to AES/EBU You can use an EtherSound interface unit such as the NAI48-ES to make a bridge connection from an EtherSound network to an AES/EBU signal.
System Connection Examples CobraNet connections You can use an interface card such as the MY16-CII to send and receive audio signals via a CobraNet network. From Amp Editor, you can monitor and control the amplifiers, and make CobraNet settings for the MY16-CII card. However on the amplifiers, the connections for amplifier control (from Amp Editor) and the connections for CobraNet are separate.
System Connection Examples Bridge connections from CobraNet to AES/EBU You can use a CobraNet interface unit such as the NHB32-C to make a bridge connection from a CobraNet network to an AES/EBU signal.
Connecting External Controllers and Analog Devices Remote control from AMX or Crestron ([NETWORK] connector) You can connect an Ethernet-compatible controller such as AMX or Crestron to the amplifier’s [NETWORK] connector, and remotely control the amplifier. When connecting a remote controller, you must specify the amplifier’s Port No. The Port No. setting can be made from the panel of the TXn amplifier or via Amp Editor. For details, refer to page 21 or to the Amp Editor owner’s manual.
Connecting External Controllers and Analog Devices Euroblock plug connection Use the included Euroblock plug (3P) to make connections to the [FAULT OUTPUT] connector. ● Cable preparation • To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration, and use stranded wire to make connections. With a Euroblock connection, the stranded wire may be prone to breakage because of metal fatigue due to the weight of the cable or due to vibration.
Adjusting the Input/Output Levels Simplified block diagram and level diagram On the TXn amplifiers, the gain / input sensitivity is adjusted by the input level before A/D conversion. The adjustable gain range is the same for the TX6n/TX5n/TX4n models. Since the maximum output is different for each model, the settable range for input sensitivity will differ for each model. The gain and input sensitivity are linked; you may edit either one.
Adjusting the Input/Output Levels Adjusting the input/output levels ■ Basic level adjustment If we think of the TXn amplifier in a similar way as a conventional analog amplifier, there are two parameters that determine the gain/level. • Gain / Input sensitivity: The input level before A/D conversion is adjusted from the front panel MENU screen ➝ [General] ➝ [Sensitivity/Amp Gain].
Appendix Message List Messages that may appear in the TXn’s display and the appropriate responses are listed below. Message Explanation Panel Full locked! To prevent unintended operation, panel operations have been locked by the panel lock setting. To temporarily defeat panel lock, hold down both the [HOME] button and [EXIT] button for at least three seconds. To turn panel lock off, first defeat it temporarily, and then turn the UTILITY screen ➝ Front Panel Operation ➝ Panel setting OFF.
Appendix Alert Message List (Excerpt) The alert message display indicates the operational status of the unit or other alert information that you specified to display via Amp Editor. The following messages appear when certain malfunctions are suspected to have occurred. For details about alert messages, including the following messages, refer to the Amp Editor Owner’s Manual.
