Dual Output Submixing
The WZ20S provides a versatile 4 mono, 8 dual stereo format for submixing a
wide variety of sources. Typical applications include on-stage stereo keyboard
mixing, and submixing effects returns to the main FOH console.
Balanced inputs
Use the stereo B input TRS jacks when connecting to long
stage cable runs. This reduces interference pickup. 48V for any
microphones that require phantom power.
Dual stereo outputs
MIX1 and MIX2 let you create two independent stereo
mixes to feed the main console. For example, you could provide two stereo
keyboard mixes for more flexible FOH mixing. Alternatively, you could use the
WZ20S for two independent submixing tasks. Use the MIX2 mono output if a
dedicated or simultaneous mono feed is required. All the main outputs are
available on balanced XLR to directly feed a professional multicore to console
system. They both provide full metering and insert points for signal processing.
Monitoring
Apart from headphones, the local monitor can be configured to
provide stereo or mono stage monitoring either as wedge speakers or IEM (In
Ear Monitor). This offers PFL override and the ability to mute the output without
upsetting the adjusted level.
Effects submixing
Fitting the optional SYS-LINK output expander card
provides a single cable connection to the main console. All the MIX and AUX
outputs as well as the PFL system are linked to the related circuits when
connecting to another ALLEN & HEATH console fitted with SYS-LINK.
Mounting convenience
Rotate and fix the connector pod as required for
flightcase, desktop or rack mounting. It is usual to install the effects or stage
submixer in a rack system together with the processing equipment.
Professional suitability
The WZ20S is built to the same high standard as top
end consoles used in major live sound applications. Its all steel construction,
together with individual circuit cards, make it ideal as a professional sidecar to
the FOH console. A high grade fader option is available as an option. The
universal mains power input allows connection to most world wide voltages.
Outside Broadcast
The WZ20S provides a compact rack mountable solution for remote broadcast
telecast or recording.
Inputs
Up to 4 announcer or ambient microphones can be directly connected
with individual phantom power selection. The input stage provides a very wide
dynamic range, particularly important during sports commentating. Use the
stereo inputs for camera, tape or effect sources, mix minus or host feeds, inputs
from submixers, stereo microphone preamps and so on.
Outputs
MIX1 and MIX2 can provide independent broadcast feeds, for
example an ‘effect’ only (ambient pick up) and ‘ announcer’ feeds. This
is useful where the ambient sound is recorded for later voiceover dubbing, such
as news report preparation. Full metering is provided on both outputs.
Additional pre/post outputs are available from the 6 AUX sends.
Monitoring
In addition to the headphones, use the local monitor output to feed
the location booth speakers. All sources can be independently checked and
metered. Use the EXT inputs for two dedicated monitor returns such as off-air
and recording returns.
