Zenith LSP204 MKII 2 In 4 Out Loudspeaker Processor
The Zenith LSP204 MKII is a professional 2-in / 4-out loudspeaker processor designed for precise control of PA and installed sound systems.
The Zenith LSP204 MKII is a powerful digital loudspeaker management system built around a high-performance 24-bit DSP engine, designed to give sound engineers complete control over system tuning, protection and optimisation. With two XLR inputs and four XLR outputs, it is ideal for configuring stereo 2-way systems, mono 4-way systems or more complex speaker layouts in venues such as live music venues, theatres, houses of worship, conference rooms and fixed PA installations.
Pre-loaded with a range of standard system presets including stereo 2-way configurations, the LSP204 MKII allows fast setup straight out of the box. These presets can be copied, edited and stored into user memory locations, making it easy to fine-tune systems for specific speakers, amplifiers and rooms. Using the supplied Windows PC editing software, technicians can also create, backup and duplicate presets for consistent deployment across multiple venues.
Each input and output channel is equipped with a full 7-band parametric EQ, allowing precise tonal shaping and room correction. Multiple filter types are available including parametric, low-shelf and high-shelf options, while the wide frequency and bandwidth ranges make it suitable for everything from subwoofer tuning to vocal clarity and system voicing.
The LSP204 MKII also includes professional crossover filters with selectable Butterworth, Bessel or Linkwitz-Riley responses, and slopes up to 48dB per octave. This makes it easy to create accurate crossover points between subwoofers, mid-range and high-frequency drivers, ensuring smooth frequency transitions and maximum system efficiency.
For system alignment and protection, the processor features up to 1 second of delay on every input and output, allowing precise time-alignment between speaker arrays. Integrated compressors on each channel protect loudspeakers from overload while maintaining consistent output levels, and phase reverse switches allow quick correction of polarity issues during system setup.
The front-panel jog wheel and LCD display provide fast access to all parameters, while LED input and output meters give instant visual feedback of signal levels. Multi-channel linking and copy functions simplify setup on complex systems, allowing adjustments to be made across multiple outputs at once. For deeper control and easier configuration, the included Windows PC software connects via USB, giving a clear graphical interface for editing, storing and managing presets.
