38. Unbalanced Master Output (Low)
Output is provided by standard unbalanced phono sockets. Level = 0dBu (775mV RMS), output impedance = < 50Ω,
load impedance = 5k Ω max.
39. AC Power Socket
A standard IEC socket is provided to connect the mixer via the supplied lead to the local AC power supply. The power
consumption of this mixer is 15V.
WARNING: THIS MIXER MUST BE EARTHED FOR SAFETY AND GOOD GROUNDED PRACTICES IN MIXING
In the event of ground-loop problems in the audio system, DO NOT disconnect the AC supply earth to any equipment before
consulting the equipment instruction manual. Most power amplifiers have audio ground lift switches or are designed
specifically to avoid ground-loop problems connected to earthed mixers.
Ensure the mixer has a clean AC supply from the mains socket that is not used for other equipment that would lead to
interference such as lights, refrigerators, etc.
The IEC power socket has an internal fuse holder that takes a 20mm fuse. Always replace a blown fuse with the same type
as specified on the rear of the mixer. Always disconnect the AC power cord before changing the fuse.
40. Earth Stud
This is an earth point for auxiliary equipment, e.g. a turntable.
