Description
You are looking at a high-performance Grace Design mic preamp built into a rugged pedal chassis. ROXi was designed to inspire new creative possibilities for performing and recording musicians. Think horn players, singers, harmonica shredders, one-mic bluegrass bands, Metal-Polka accordion acts. Now you can tweak and perfect your own microphone sound on stage or in the studio.
It starts with a precision rotary switch gain control, which levels up the audio performance, especially in higher gain ranges (ribbon mics welcome). A 2 position high pass filter gives excellent control of problem bass / rumble areas at 75Hz or 150Hz. A 3-band EQ with sweepable mids rounds out the tone shaping. The FX loop can be defeated by a footswitch and has an onboard blend control to run your effects at 100% and adjust wet / dry amount on the preamp. The input is a combi XLR / 1/4″ jack, so it can run as an instrument preamp like its buddy ALiX .
Features:
- Mic / Instrument input with 48V phantom power
- Switchable 75Hz or 150Hz High Pass Filter
- 3 Band EQ w/ High, Low and sweepable Mid
- FX loop with a footswitch for FX mute
- FX Mix control
- Variable Boost circuit
- ¼ in Amp output w/ independent level control
- Mute switch
- XLR balanced ISO output
- Universal 100-240 VAC power supply
Why a MIC PREAMP pedal?
Singers
A singer can plug their favorite microphone into a Grace Design mic preamp with their own effect pedals in the FX loop and control their reverb, old-timey AM radio or distorted vocal effects however they want. Singers with pedal boards? Your time has come.
Horn Players
Horn players looking to expand their sonic palette. Flugelhorn into a wha-wha pedal with distortion and delay? All day. Baritone sax through an octave pedal? Dude.
In the Studio
Recording engineers can harness the creative possibilities in the studio by inserting various guitar effect pedals into their recording signal chain. The possibilities are vast.
Acoustic Music
Hardworking one-mic bluegrass bands with their very own high-fidelity Grace Design mic preamp on stage. If the banjo and bass player get in a fight, someone can please just tap the mute switch while they sort it out. Embarrassing situation averted.
Creative Souls
Any sonic explorer looking to add a single channel of Grace Design preamp to their kit with some unexpectedly cool extra features. Nice.
