DC POWER CONNECTOR

5Pin

male XLR for connection to Allen

Heath power supply unit. MPS-8R is

normally supplied with the Scepter, but an

MPS-8P,

MPS-9, or RPS-1 with the

proper cable can also be used. Your warranty will be void if a power supply not

supplied or approved by Allen

Heath is used.

The Scepter is designed to allow. the user to lift the chassis from the audio

ground. This is useful in rack mounting situations since the rack rails may be at

different potential than the audio ground. This can cause ground loops. By allowing

the chassis to be lifted from the audio ground, the ground loops can usually be

eliminated. See the USER CONFIGURED OPTIONS section for this procedure.
