Hum Kleaner

HUM KLEANER

Earthquake Sound’s Hum Kleaner is designed to eliminate Hum at the source while also amplifying the purified signal so that it may be pushed over long wire runs. In addition to eliminating common hum issues, it is equally important that your amplifier receives the required signal voltage to maximize available performance. If your powered equipment is not receiving the required signal voltage then it is impossible to perform at the level that the manufacturer intended. That is why the engineers at Earthquake Sound decided to integrate a pre-amplifier into the Hum Kleaner’s noise-suppression- circuitry. This device is not just a line converter, on-board is an amplifier capable of boosting a signal to 9V (RCA) or 18V (TRS/XLR).

The Hum Kleaner provides two channels of unbalanced-to-balanced level conversion and two channels of balanced-to-unbalanced conversions in a resilient, compact, and portable unit. The Hum Kleaner can be a valuable tool in application areas such as home, professional recording studios, live sound, PA, DJ, AV or anywhere else where signals need to be pushed long distances while retaining clarity. It also works with mixers, audio, processors, laptop computers, CD/DVD players, gaming consoles, powered monitors, and digital workstations.

The Hum Kleaner is a pre-amp unit that takes the input from an RCA (non balance), TRS (balance or unbalance), and XLR (balance or unbalance); then the switch will allow any of these input to activate the unit. Thereafter, there is a gain knob that allows the user to increase the gain level. Thereafter, the Hum Kleaner isolates the ground, and the positive of the input and the output from any type of connection. Therefore it kills any change of a ground loop while it amplifies the signal.

Design Uses

Vinyl Disk Player

Vinyl disk player’s product has a weak signal under 50 mv. The Hum Kleaner will act as a pre-amp for this signal. The THD+NOISE= 0.0003 at 1000 HZ. The gain at max will allow 18dB gain (three times the input level) on RCA. The max gain on XLR allows for 24 dB (four times the input). Example: The vinyl disk player will have about 50 mv input into the Hum Kleaner will have a 0.6 VAC out on the RCA and a whopping 1.8 volts AC signal on the XLR.

Recording Studio Headphone Type

This offers a massive control for headphone as it increases the signal to noise and signal level.
DJ, live concert, live band it will isolate the input signal from causing any problems. This offers an instrument’s isolation for guitar players, singer, or any other input instrument from causing hum problems into the mixer. Furthermore the Hum Kleaner amplifying function will be used as a level control that will match the sources.

Live Music

For DJs, live concerts, or any other live music applications, the Hum Kleaner will isolate the input signal from causing any problems. This offers isolation for guitar players, vocalists, or any other input instrument from causing hum problems into the mixer. Furthermore the Hum Kleaner’s amplifying function will be used as a level control that will match the sources.

Microphone Amplifier

Signal Driver

The Hum Kleaner signal driver function is used when the installer has an audio source, DJ, control room, or any application where the install has an excessive distance of 100ft. and up to 400ft. These distances are between the audio source and powered speakers such as DJ 2.1, DJ10, and DJ8. The Hum Kleaner would amplify the signal up to 16 VAC while it is transported around power lines that generate magnetic flux which inductively generate hum into any wire. So the Hum Kleaner drives up the signal and then it allows a clean transportation. This type of install is suited for a pair of Hum Kleaners to drive signal and then 400 feet later the HLLC-200 would be used to reduce the signal into 1-3 Volts AC to drive any products without any hum.
