Soundtube MCA2004t 4x200W Low Voltage Amplifier / 70V/100V Outputs / Matrix Mixer / Class D

Description

The MCA2004t is a rack-mount low voltage power amplifier designed for commercial and professional audio installations. It delivers four independent channels of amplification with both low-impedance direct outputs and constant-voltage 70V/100V outputs. The unit combines amplification and input routing in a compact Class D package ideal for distributed audio systems.

Key features include four channels offering up to 200 watts per channel at 8 ohms and selectable constant-voltage outputs for distributed speaker systems. An internal matrix mixer lets any input feed one or multiple outputs, providing flexible source routing. Selectable high-pass filtering and dedicated subwoofer mode give control over low-frequency management to prevent amplifier clipping and speaker overload.

Performance specifications emphasize clean power delivery and frequency accuracy, with output figures spanning 100 watts RMS at lower impedances to 200 watts RMS at standard 8 ohm and 70.7 V conditions. Frequency response extends across the audible band at 20 Hz to 20 kHz ±3 dB. Damping factor exceeds 32, and input impedance is specified at 8.6K ohms for both balanced and unbalanced sources.

Connectivity is provided via Euroblock-style connectors for balanced and unbalanced audio, plus controlled constant-voltage outputs for 70V and 100V speaker lines. Input routing via the onboard matrix mixer supports flexible source-to-zone mapping. The amplifier includes Euroblock accessory connectors and a standard IEC power solution for simple integration.

Typical use cases include background music distribution, zoned paging systems, and multiroom audio in retail, hospitality, and institutional environments. The MCA2004t supports mixed speaker types and zoned deployments where centralized control and reliable constant-voltage outputs are required. Subwoofer mode and high-pass filters simplify system tuning and crossover management.

Installation is straightforward with standard 19 inch rack width and 2U height, Euroblock input/output terminations, and rack-mountable chassis. The amplifier provides front and rear controls for routing and filtering, and its Class D topology helps reduce heat and power draw. Build quality and certifications ensure compliance with common commercial installation standards and long-term reliability.
