How to use

Recommendations

Use moderate reverb settings for close-miked vocals to maintain intelligibility; increase pre-delay or reduce wet mix for live applications in reverberant rooms. Regularly check gain staging and use the unit's tone controls to reduce muddiness or harshness based on the vocalist and microphone characteristics.
