Self-powered 12” subwoofer with 3 digital amplifiers and 4-channel DSP, 2 x 350W (RMS), 1 x 1.000 W (RMS)

The IN312SUB is an active subwoofer system in a rectangular chassis for fixed installations and mobile use. The cabinet is equipped with one high performance 12" speaker (neodym). The two integrated tripod bases (M20) enable the use of a distance rod in combination with a MF/HF speaker (i.e. IN6). The IN312SUB suits for speech and music applications as subwoofer speaker in sound reinforcement systems. The chassis is constructed from 15 mm plywood (birch) and covered with black NOVA PolyCoat© coating. The cabinet is equipped with eight grip handles and a front grill with transparent charcoal foam backing.

The IN312SUB subwoofer includes a SMPS (switch mode power supply) and three integrated digital amplifiers. The digital amplifier for the subwoofer drives the internal speaker as well as the passive subwoofer IN12SUBP via a NL4 speakon connector (pins 2+/2-, available as option) with a power up to 1 x 1.000 W (RMS). The two digital amplifiers for the satellite speakers offer a power up to 2 x 350 W (RMS) via a NL4 speakon connector (pins 1+/1- ). The output power can be adjusted at in DSP with a preset according to the power rating of the speaker cabinets.
Inputs the analog input stage is equipped with two XLR connectors (stereo). The input stage is equipped with a digital XLR connector for input and one for connection to another subwoofer (loop thru).
The input section offers 6 parametric EQ, delay and a noise gate. The input channels also offer a HPF (high pass filter), and a LPF (low pass filter). Both types of filter (HPF and LPF) may be used in the operating modes "Linkwitz-Riley", "Butterworth" or "Bessel" (up to 48 dB / Oct).
The four output channels DSP offers 6 preset equalizers (operation mode "Low-Shelf", "High Shelf" or "Parametric EQ"). All four channels offer delay and a switch of polarity (+ / -).
1. DSP cha. > To subwoofer 2. DSP cha. > To the left satellite speaker 3. DSP cha. > To the right satellite speaker 4. DSP cha. > It is available through an XLR output on the rear panel. This fourth DSP-channel can be used for example for the creation of a low-cut filter as signal processor "PRE" of an external active monitor. It can also be used to monitor external active equalization in order to optimize the suono.Tutte DSP settings can be changed via the PC software or remote diplay LCD 2 x 20. 20 presets can be stored in internal memory (flash).
PC remote software The DSP can be adjusted and controlled with the free PC software. This software is a professional tool and enables a quick and effective programming of presets in real-time (online or offline). The program shows adjustments of any filter in a graphic simulation. All DSP-functions and adjustments can be loaded, edited and saved with this tool. The software is compatible with WINDOWS 98©, WINDOWS 2000©, WINDOWS XP©, WINDOWS VISTA©, WINDOWS 7© and WINDOWS 8© (all 32-bit and 64-bit versions).
