Soundstandard GTM Series features a high-efficiency power system with Class-D digital amplification technology, achieving 98% ultra-high energy conversion efficiency and a 300% increase in power density. The SMPS regulated power supply provides 14,000W dynamic power reserve and supports global voltage auto-adaptation (100-240V). With active PFC (Power Factor Correction), it delivers THD+N <0.025%, SNR >105dB, and a dynamic range >105dB. Under a 2.7Ω load, each channel outputs 3300W continuously, effortlessly driving large line array speakers. Its millisecond-level transient response ensures precise reproduction of dynamic sound effects and delicate vocals.
GTM33.4 is equipped with a dual-core DSP processor for real-time IIR+FIR hybrid filter algorithm processing. It precisely calibrates linear phase curves, optimizes impulse response, and restores a “zero coloration” transparent sound field. Supporting 96kHz/40bit high-resolution processing, it offers multi-scenario EQ presets for theaters, live performances, and fixed installations. The unit includes 4×4 balanced XLR inputs/outputs and dual AES/EBU digital channels, with Ethernet remote monitoring (RJ45). Free sound field configuration solutions and a DSP preset library are provided (exclusive for GTM33.4 users).
