The Satrix MS512 HQ is a multiswitch with 4 satellite inputs, 1 terrestrial input, and 12 subscriber outputs. It is part of the MS 5x HQ series, built with components from mobile technology to achieve lower operating temperatures and reduced running costs compared to internally powered units.

An external power supply keeps heat generation inside the unit to a minimum, extending component life and improving long-term reliability. The terrestrial path is passive (no amplification), and the unit is fully compatible with return-channel systems for interactive satellite services.

Key Features

• 5 inputs: 4 SAT (Quattro or QUAD LNB only) + 1 terrestrial passive
• 12 subscriber outputs for simultaneous independent receiver connections
• External power supply for energy-efficient, low-temperature operation
• Return-channel compatible for interactive services
• Supports HD+, 3D, 4K, UHD, Ultra HD, and SKY reception
• Mounting feet included for secure wall or rack installation

Product Benefits

• Lower internal operating temperature extends product lifespan
• External PSU reduces electricity consumption and operating costs
• Passive terrestrial path avoids over-amplification of the terrestrial signal
• Return-channel support enables video-on-demand and interactive TV services
• Compatible with all current and next-generation satellite broadcast formats
