GLI-200
GROUND LOOP ISOLATOR
The Earthquake Sound GLI-200 is a device that was designed to resolve MOST ISSUES of GROUND LOOP
NOISE or buzzing which can be common in audio systems due to ground loop. The standard A/V receiver
output is 600Ω yet most ground loop isolators on the market today have 200Ω at best. If using a substandard
product, your A/V receiver has to deliver 3X more current and or compromise the output level. The GLI-200
comes with an impedance of 600Ω right out of the box matching that of the industry standard. Unlike other
products on the market, Earthquake's GLI-200 is constructed with high-quality components and will not roll-
off the low frequency response due to undersized transformers resulting in substandard performance. The
GLI-200 was designed to remedy MOST situations where a ground loop creates an unwelcomed hum or buzz
noise that some experience in their audio systems. The compact and rugged construction of the GLI-200
allows for it to fit into virtually any audio system and can be mounted to any surface with its built-in mounting
bracket. This will give you a cleaner looking install and allow it to be hidden out of sight. The GLI-200 can be
applied to a range of applications that accept an RCA input and output.
Do not panic if you find that the GLI-200 increases noise. You will need to locate the source of the
noise, trap it , and kill it. Please refer to the A/V System section of this guide for more details.
Earthquake Sound recognizes that not all hum or buzz noise situations are the same and encourages
you to contact tech support if you need further assistance.
