JBL MPX1200
Very little is documented about the JBL MPX1200. The record shows it was a professional power amplifier, listed in a database of JBL Professional products. That is about all anyone has verified.
The MPX1200 shows up in period tour and sound-reinforcement coverage. EQ (1997, p.98) mentioned it in a system that used four MPX1200s for low-end power in a live venue. These mentions confirm the unit worked in professional touring in the mid-1990s. Neither review gives amplifier specifications.
No production years, original price, power output, dimensions or weight have been found for the MPX1200. A recurring mix-up makes the research harder. Some sources filed under the MPX1200 name actually describe the JBL MRX500 series loudspeakers (MRX515, MRX512M, etc.), a completely different product category. Those loudspeaker specs - the 12" driver, 250 W continuous / 1000 W peak ratings, 95 dB sensitivity - belong to the MRX line, not to this amplifier, and should not be attributed to it.
Known facts:
- Professional power amplifier by JBL Professional
- Used in live sound / tour reinforcement in the mid-1990s
- Cited in EQ (1997, p.98) in a professional audio context
If you own an MPX1200 or have service documentation, the Archive would welcome the missing specifications.
