Rolls HR341 overview

  • 1Description

The Rolls HR341 is an audio processor suitable for use on vocals and acoustic guitars, primarily in live-sound scenarios. It provides a low-shelf EQ for curtailing bass, a high-shelf EQ for shaving excessive trebles, and a notch filter for eliminating feedback at various fundamental frequencies. Both shelving EQs are 24 dB/octave filters, and can be used to minimize rumble on the low-end or shrillness in the upper register. Also on hand are a soft-knee, optical-style compressor for smoothing the signal, and a TRS send/return insert path for looping in external processors.

For connections, the HR341 offers a 1/4" TS input, a 1/4" TS output, an RCA unswitched output, the aforementioned 1/4” TRS send/return jack, and a 3.5mm headphone output. When you connect to the headphone output, the 1/4" speaker/line output will be muted, but the RCA output will pass sound unaffected.

This signal processor has a power amp rated at around 2W, which is suitable for driving various speakers, though you’ll find this unit most useful as an insert for your existing mixer, as it can shape the tone of a channel in a minimal, yet supportive way. You’ll find an impedance switch on the rear to switch between 8-Ohm and unterminated operations; this lets you use the HR341 with a variety of gear, including tube-powered and solid-state units. An AC adapter is included.
