and check voltage requirements. BEWARE that 48v is
likely to burn them out.
xiii) Dynamic Microphones: Included the popular SM57
and may connect via XLR or Jack but do not require
powering and are not damaged by Phantom Power. They
are often tough and reliable but not terribly sensitive and
have an uneven frequency response. They usually
benefit from treble boosts and mid cuts. Most are for
external use on stands but miniature versions do exist,
often used primarily for drums or woodwind
3.1 CABLE / LEADS NOTES:
Suitable Jack leads as used to the Input of the EDB-2
H.E should have at least 80% screening, preferably
braided or, at least, conductive plastic shielding with
extra extensive lapped screening to minimise hum and
radio interference
Denmark can have a particular problem with hum when
using Mains electricity to run a sound system, because
there is no mains earth. So everything has to be
exceptionally well shielded, particularly at high
impedance
High quality leads as short as practicable with metal
covers are generally recommended
