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. Amp E

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. Each TXn unit has 50 scenes. ■ Signal Path This is the audio signal processing functionality provided by the i

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%). The [PROTECTION] indicator will light at 80°C (80%) or higher. • If the power supply overheats and s

Controls and Connectors ■ Removing and installing a card To remove and install a card, proceed as follows. 1. Make sure that the power of the TXn is turned off. 2. Loosen the screws that fasten the slot, and remove the installed card. Keep the removed card in a safe place. 3. Align the two edges of the card to be installed with the guide rails inside the slot, and insert the card into the slot. Push the card all the way into the slot so that the contacts of the card are correctly mated with the
