Allen & Heath 29 ZED POWER 1000
CONNECTING THE AMPLIFIER
Speaker outputs
The power amplifier outputs are available on
Speakon connectors. These are robust locking
connectors specifically designed to carry high
power signals.
The popular NL4 version is used. Wire the
speaker positive cable to the 1+ terminal and
the speaker negative cable to the 1- terminal.
Use heavy duty 2 core speaker cable of at least
16swg (1.5mm 2 ) rating.
To connect the speakon push in the plug and
rotate. This locks the plug in position. If the plug
is not rotated then there will be no connection
and consequently no amplifier output.
Speaker Impedance
Live sound speakers are typically 4 ohm or 8
ohm.
Usual application is one speaker per amplifier
channel but you can also add speakers togeth-
er in series and parallel in certain situations.
The ZED1000 mixer is rated at 500W music
power per channel into 4 ohm speakers. The
output power is reduced into 8 ohm loads and
so you could put two 8 ohm speakers in parallel
on either channel of the amplifier to gain more
power (Please see our connection diagrams for
some examples of how to connect the mixer in
various scenarios).
NOTE: Loads of less than 4 ohms per channel
should not be used and could damage the am-
plifier. Also do not attempt to bridge or cross
connect the channels in any way as this could
also lead to permanent damage.
