chassis connectors are
fitted to the UniAmp 1214. The Input connector
(coloured blue) is a Neutrik
®
Type A, and is intended
for connection of the AC mains supply; the Link
connector (coloured grey) is a Neutrik
®
Type B, and
is to facilitate connection to another module in an
adjacent enclosure.
Note that the Link connector is not
independently fused.
The full-load power consumption of the amplifier
module is model dependant but does not exceed
250 VA, please refer to the individual data sheets for
model specific information. When “daisy-chaining”
AC mains between several enclosures of the same
type using the Input and Link connectors, ensure that
the current capacity of the supply is sufficient for
ALL amplifiers in the chain, and additionally, that
the total current drawn by all the amplifiers does
not exceed 16 A.
In practice, this means that the maximum
number of amplifiers (including the first
one) that may be daisy-chained in this way
is fifteen (230 V operation) or eight (115 V operation).
Only wire AC mains connectors according to the
table below:
