TTM12K4

Documents

The TTM Series is a versatile, 4-channel 2U amplifier platform integrated with a full suite of professional signal processing tools – including 2048-tap FIR filters, Damping Factor Control and Dynamic EQ. It features flexible analog, AES3, and Dante/AES67 input and output connectivity, plus a high-brightness 4.3” IPS capacitive touch display for intuitive local operation.

Boasting abundant power and voltage headroom, the TTM Series delivers impressive SPL performance even with 8Ω or 16Ω loads, and is capable of a robust 4 x 2000 W output into 4Ω loads. Its patented, PFC-equipped power supply enables global operability and incorporates 750J of energy storage, ensuring consistent, reliable performance in any application.

Local control via the on-board display interface grants easy access to core functions including preset recall, gain adjustment, delay tuning and muting – perfectly meeting the day-to-day operational needs of most rental companies. For remote management, the TTM Series is fully compatible with ArmoníaPlus software, enabling seamless centralized control.
