The TQP-48 is a 4-input, 8-output digital signal processor that provides full support for Fulcrum Acoustic’s FIR-based, Level 1 Temporal Equalization™ (TQ™) loudspeaker settings. Fulcrum Acoustic loudspeakers tuned to Level 1 provide a crisper stereo image, greater soundstage depth, more separation between the components of a complex mix, increased resistance to feedback, improved array-ability, more seamless transitions between distributed loudspeakers, and a less fatiguing listening experience at very high SPLs. Level 1 settings are imported to the TQP-48 by means of pre-configured voicing files, which are published on the Fulcrum Acoustic website (www.fulcrum-acoustic.com).
The TQP-48’s DSP signal processing library is extensive and utilizes multiple SHARC 32-bit processors. Processing blocks include an 8 x 8 matrix mixer, a full array of graphic and parametric equalization, multiple crossover filter types, an advanced feedback suppressor, auto-levelers, compressors, matrix duckers, limiters, frequency-keyed noise gates, delays of up to 1365 ms on every channel, and signal generators.
All programming is accomplished with Ashly Protea™ NE Software running under Windows, with communication provided by either TCP/IP via standard Ethernet, or RS-232 via a 9-pin D shell connector. Hot-plug software control allows you to plug any processing block into any channel block, even while running live audio; recompiling is not required. Automatic DHCP network IP configuration allows quick and easy network set up, while the lack of front panel controls and multi-level software security with password access assure a tamperproof audio system.
Additional features include 8 channels of programmable 5-volt input or output logic controls, 8 channels of 0-to-5-volt analog level control, front-panel meters, and mute buttons.
