Using the E1 with a Rolls Personal Amplifier

FAQ #2350 Updated July 31, 2007


I have an existing in ear system using a Rolls PM50 Personal Monitor and Rolls CL151 Compressor Limiter with a cheap set of buds.

The problem is in the earphones. I am using a cheap set, and wish to upgrade. If I was starting from scratch I would buy the Shure system hands-down, but I do not wish to rebuild the entire system because of a limited budget. I have heard great things from my music store about the E1's. Can I plug the E1's into the Rolls PM50 using a 1/8 to 1/4 adapter and would it be a recommended setup ?

Thanks in advance - keep up the great work !


The impedance of the E1 earphones is 16 ohms. Ask Rolls if the Rolls device can drive a 16 ohm load, If yes, you may use the E1 earphones.
