Ground loops are the enemy. Fortunately, GearNuts has an effective defense: the Radial Twin-Iso. The Twin-Iso is a 2-channel, balanced line-level isolator designed for sound installation, broadcast and recording studios, and pro touring. It gives you isolation between audio gear like consoles, amplifier racks, recorders, and remote towers to eliminate buzz and hum due to ground loops. The Twin-Iso is fitted with two high-performance Eclipse transformers that deliver linear response at every frequency and can handle up to +21dB without distorting.
