商品描述

Earthquake 音频解决问题系列扩展:GLI-200地面循环隔离器。标准 A/V 接收器输出为 600Ω,但如今市场上大多数地面环路隔离器都有 200Ω。使用这些次标准产品时,您的A/V接收器必须提供3倍以上的电流或影响输出水平。 GLI-200 开箱即用即有 600Ω 的阻抗,符合行业标准。 Earthquake 的 GLI-200 采用优质组件制成,由于变压器体积小,不会产生低频率响应,从而导致性能不佳。它旨在减少大部分可怕的嗡嗡声和接地环路噪音,同时保持音频系统的高品质声音。 GLI-200 的紧凑坚固的结构使其几乎可以适应任何音频系统,并可以通过内置安装支架安装到任何表面。这会给您一个更清洁的外观,并将其隐藏在视线之外。不是所有的嗡声或嗡声噪音情况都是一样的 – 按照 Earthquake Sound 布线指南实现最佳性能。谈到音频噪音和嗡嗡声问题,GLI 200 为日常家庭和汽车音响爱好者面对的大多数地面环路问题提供了很好的解决。

couldn't believe how well this works. plagued by line hum, had both amp and preamp recently rebuilt and serviced ( unit is harmon kardon from early seventies) . added this into preamp line and NO HUM WHAT-SO-EVER. this unit is GOLDEN to a hi-fi fanatic!

Too much standby noise and 5x hum through R speaker compared to L

2022年7月17日 - 已在美国亚马逊上发表

First, on standby (no audio input at all including 0 hum or buzz) this device creates too much of its own noise. I am using for whole house audio and I cannot tolerate a background hum at all times as this device creates.
Second, for some reason this device creates significantly more hum through the right compared to the left, this is bizarre and seems like a design flaw. In case your thinking it was my audio source, I switched the L and R inputs and still the right output hummed 5+ times more than the left?

Got rid of 90% of noise coming from computer HDMI

2022年10月2日 - 已在美国亚马逊上发表

样式: 接地环隔离器 + 信号转换器已确认购买

I've been chasing ground loop buzz issues in my media system, which are no doubt self-inflicted due to my overcomplicated setup (computer source feeding a Denon receiver via HDMI, splitting out to vintage amplifiers via zone 2 RCAs, through RCA to XLR cables, to active crossovers, to ML electrostatic speakers). None of the speakers that are powered off the Denon receiver itself have noise that I can hear, only those powered by external amplifiers.

I had previously used star grounding on all the RCA shields to the receiver chassis ground, and moving ALL equipment to the same wall outlet, which helped some, but not all of the problems (got rid of flourescent and LED bulb noise from other outlets/breakers in the house just by consolidating the audio/computer equipment to a single outlet). Ultimately, the noise was coming through the HDMI from the computer to the receiver, and then being passed to the amplifiers.

This product solved 90-95% of the processor power noise passing through the RCAs to XLR inputs on the outboard crossovers. I'm still going to obsessively chase down the last bits of noise reduction, but all in all, this product is worth it's price and then some
