Page 3: Introduction
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. -
Page 4: Terms
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 com- puter. ■ 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. -
Page 5: Controls And Connectors
Controls and Connectors Front Panel [POWER] switch and indicator This switch turns the amplifier’s power on or off. When you turn this switch on, the [POWER] indicator will light white. In Standby mode, it will light white as well. [STANDBY] indicator This indicator will light orange when the amplifier’s power is in Standby mode. - Page 6 Controls and Connectors [PROTECTION] indicator When the protection system is active, this indicator will light red. The protection circuit will operate in the following situa- tions. • If the amplifier overheats and the output limiter operates The speaker output will be attenuated if the heat sink of the amplifier section exceeds 80°C (80%), and will be muted if the heat sink exceeds 90°C (90%).

Page 44: System Connection Examples
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 sig- nals (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. -
Page 45: Thru-Output For Digital Connections
■ 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. If the power is on, the signal is regenerated in the buffer, theoretically allowing daisy-chain connection of any number of units. -
Page 46: Redundant Connections (Backup)
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. -
Page 47: Ethersound Connections

Page 53: Adjusting The Input/Output Levels
On the TXn amplifiers, the gain / input sensitivity is adjusted by the input level before A/D conversion. The adjust- able 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;... -
Page 54: Adjusting The Input/Output Levels
■ Level adjustments between TX6n/TX5n/TX4n units In a system where different TX6n/TX5n/TX4n models coexist, set the same gain on each unit if you want to obtain the same output level (V, dBu) for a given input level. These settings are convenient when you need to manage the gain in a multi-way speaker system. -
