Meyer Sound MJF208 Powered Stage Monitor Speaker
Meyer Sound MJF208 Powered Stage Monitor Speaker
The MJF‑208 compact stage monitor brings the same high intelligibility and low-frequency headroom of Meyer Sound’s acclaimed MJF line of stage monitors to a lighter, more portable cabinet. The MJF‑208 is ideal for monitoring applications with minimal stage space that do not require the higher output of the MJF‑212A or MJF‑210. All three stage monitors offer the self‑powered advantages of simplified setup, operation, and consistent stage-to-stage sound, while occupying a fraction of the truck space of similar monitors that require external amplification.
Features:
- Small lightweight footprint with no external amplification occupies less stage and truck space
- Self-powered system simplifies setup and operation and ensures consistent stage-to-stage sound
- Low-profile cabinet preserves audience sight lines
- High peak power ensures excellent transient response
- Flat phase and frequency response and exceptional pattern control yield high gain before feedback
