How to Choose the Best Splitters and Combiners
Isolation
Broadcast signals need to be clean. Poor isolation between channels means bleed-through and phase cancellation, muddying the mix and making it impossible to properly EQ individual elements. You want at least 60dB isolation, preferably more.
Noise Floor
Even the best mics can be ruined by a noisy splitter. A low noise floor is critical; anything above -90dB referenced to 1V is a red flag. It'll creep into your signal, especially when you're dealing with quiet vocals or delicate instruments.
Phase Response
Phase shift is the silent killer. Even subtle phase shifts can negatively impact the perceived clarity and imaging of your broadcast. Look for splitters with minimal phase distortion across the audible spectrum - ideally, within 1 degree.
Impedance Matching
Mismatched impedances can cause signal loss and reflections. A good splitter will maintain consistent impedance regardless of the connected equipment, preventing unwanted coloration or frequency response changes. This is especially important when feeding multiple consoles or recorders.
Build Quality & Power
Let's be honest, broadcast environments aren't gentle. You need something that can handle the bumps and the heat. A robust power supply and solid construction are non-negotiable; a flimsy unit will fail when you need it most.
Buying Guide
Don't chase the biggest number of ports; focus on quality first. Cheaper splitters often cut corners on isolation and noise performance, which will negate any benefit from having more outputs. Spending a little more on a reputable brand - Radial, Countryman, BSS - is an investment in reliability and a clean signal. And always, always check the power requirements and make sure you have a clean power source to avoid hum and noise.
Our Methodology
We don't just look at spec sheets; we put these units through their paces. That means A/B comparisons against known-good references, feeding them hot signals to test headroom, and simulating real-world broadcast scenarios - think multiple mics, long cable runs, and potential interference. We're listening for noise, phase anomalies, and overall signal degradation - the stuff that affects the final sound.
