EarIn

Stereo headphone preamp for in-ear monitoring

Introducing Nowsonic EarIn

The Nowsonic EarIn is a compact, stereophonic amplifier unit which amplifies the incoming signals to connected in-ear or circumaural headphones. EarIn can be fed with a stereophonic or two monophonic signals which are connected via the two balanced XLR inputs. Depending on the chosen mode (Mono or Stereo), a Balance knob sets the level control for both inputs.

EarIn provides high output power which makes this monitoring solution especially suitable for stationary use on stage or in the recording studio.

Drummer, keyboard or wind players can adjust the level of the monitor signal as required while an integrated limiter protects the unit from clipping.

In-ear or circumaural headphones (not supplied) like the Nowsonic Prinz can be used. Nowsonic EarIn can be comfortably mounted to the belt via a clamp. Power can be supplied via a 9 V battery (optional) or the DC adapter (included).

Reviews

“Especially for drummers Nowsonics wired Ear-In-Monitor is well suited. Our test revealed a very valuable construction.”

“With the EarIn Nowsonic continues its line of practical helpers for the stage and studio everyday life.”

“The Nowsonic EarIn is a great sound and volume amplifier. If the input is right, there’s nothing to complain about. For a retail price of less than 100 € you can get something here. Also regarding robustness and haptics everything is right. The device feels as if you could still rely on it without hesitation even after hundreds of rehearsals and concerts. What more do you want?”
