Crown Macro-Tech 2400 & 3600VZ original power plugs?

(1/3) > >>

Thomas Le:
My church has two 2400's for two Yamaha F15 tops per side (one per channel, 8 ohms) and two 3600VZ's for two Yamaha F28 subs per side (one per channel, 4 ohms), both are modified with 15A edison plugs (amps are 120V 60Hz USA edition).
What are the original power plugs for each respective amp?
Stupid question but is it safe to continue operating both amps using the 15A edison plugs?

Provided the cct breaker for that outlet is rated the same as the plug and cord, it is "safe" to operate.
I know with the VZ5000 amps , I used a 30 amp plug for 120 volt operation.
Depends (I know....) how much load you have on them and how hard you drive them.
Unlike some of the "modern" amps, these older Crowns like a good solid voltage supply.
Your application is reasonably light so you should be OK.

That appears to be a NEMA TT-30, usually used for recreational vehicles. Outside of the RV industry, a NEMA 5-30 or NEMA L5-30 plug is usually used for 30A 125V service.

It's similar to a NEMA 7-15 or 7-20, but I believe those are a smaller diameter and only for 277V single phase.

It is what it appears to be and yes, that is how it was shipped from the factory.  In the field you frequently find them with 5-15.
