REAR PANEL FEATURES AND CONTROLS 1 FEMALE XLR INPUTS (BAL/UNBAL) The speaker SIGNAL INPUTis an XLR female connector designed to accept XLR cables, which are commonly used in professional audio setups. These connectors provide a balanced signal path.. 2 MALE XLR LINK OUTPUT This output connector is designed to provide a parallel audio signal output, enabling seamless daisy-chaining of multiple speakers. This balanced XLR connector sends the audio signal to other amplified speakers, or supplementary amplifiers, ensuring flexibility and reliability in various professional audio applications. 3 SYSTEM VOLUME KNOB It is a rotary control that adjusts the overall output level of the system. By turning the knob clockwise, the volume increases, and turning it counterclockwise decreases the volume. This control allows precise adjustments to the system's sound output, ensuring the desired audio level for different environments or applications. 4 SIGNAL / LIMITER LED The Signal LED lights up green when an audio signal is detected at the speaker's input. This provides a visual confirmation that the system is receiving an active audio signal. The Limiter LED turns red when the speaker's built-in limiter is activated. This function protects the speaker from overloading by reducing the input level when it approaches unsafe thresholds. If the LED occasionally blinks red, the system is operating normally. However, if it stays red continuously, it indicates the input level is too high and should be reduced to avoid distortion or potential damage. 5 POWER LED This green LED lights up when the speaker is connected to the main power supply and switched on, indicating it is ready for operation. 6 LINK LED This LED illuminates to indicate that the speaker is successfully connected to the RDNet network, confirming its integration into the RDNet control system. 7 ACTIVE LED This LED blinks to indicate that the speaker is actively transmitting data over the RDNet network. It serves as a visual confirmation of ongoing data communication within the system. 8 RDNET DATA INPUT AND DATA LINK The RDNET IN/OUT PLUG SECTION features etherCON connectors designed for the RDNet protocol, which facilitates seamless communication and control of the speaker via RDNet software. This connection allows users to remotely configure and manage various parameters of the speaker system, making it ideal for complex audio setups where multiple speakers need to be synchronized and monitored in real-time. The RDNet system offers a comprehensive control solution, providing detailed feedback and adjustments for optimal performance across all networked devices. 9 FLAT / HIGH PASS The Flat / High Pass button allows you to toggle between two equalization modes. When set to Flat, the speaker outputs sound without any frequency modifications, offering a natural and uncolored response. When set to High Pass, the speaker applies a high-pass filter, which removes lower frequencies below a certain threshold, useful for applications where you want to prevent distortion caused by low-end signals or to use the speaker in a system with subwoofers. 10 BYPASS / LOCAL SETUP When the BYPASS button is pressed, the speaker loads its setup from the internal memory, which can only be written to via RDNet. This setup is saved automatically, so when the speaker is powered on again, the last stored configuration is applied. When the button is released, the speaker switches to its local setup, meaning that it will no longer recall the RDNet configuration on subsequent power-ups. Instead, it will use the default or previously set local configuration.. 11 POWERCON INPUT SOCKET PowerCON TRUE1 TOP IP-Rated power connection. 12 POWERCON OUTPUT SOCKET Sends the AC power to another speaker.

At first verify the voltage label applied to the rear panel (115 Volt or 230 Volt). The label indicates the right voltage. If you read a wrong voltage on the label or if you can't find the label at all, please call your vendor or authorized SERVICE CENTRE before connecting the speaker. This fast check will avoid any damage. In case of need of changing the voltage please call your vendor or authorized SERVICE CENTRE. This operation requires the replacement of the fuse value and is reserved to an SERVICE CENTRE. BEFORE TURNING ON THE SPEAKER You can now connect the power supply cable and the signal cable. Before turning on the speaker make sure the volume control is at the minimum level (even on the mixer output). It is important that the mixer is already ON before turning on the speaker. This will avoid damages to the speaker and noisy "bumps" due to turning on parts on the audio chain. It is a good practice to always turn on the speakers at last and turning them off immediately after their use. You can now turn ON the speaker and adjust the volume control to a proper level. PROTECTIONS TT+ Audio active speakers are equipped with a complete system of protection circuits. The circuit is acting very gently on audio signal, controlling level and maintaining distortion at acceptable level.
