signs of damage. Report any shipment damage to the carrier at once. The
following accessories are included with the LXP-5:
1. Quick Reference card
2. Owner's Manual
3. Power pack (USA Part # 470-07345)
4. Warranty card (USA only)

cableendtotheLXP-5 powerconnector.TheLXP-5 mustbeusedonlywith
the supplied power pack. Voltage requirements are printed on the power
pack.TheLXP-5has nopowerswitch–it canbelefton allthetime.Tokeep
thepower plug fromworking loose fromthe rear ofthe unit duringtransport,
you may wish to apply a small amount of silicone sealer to the plug after
inserting it.
Mounting
TheLXP-5measures8.5"Wx1.7"Hx9.5"d(215.9x43.2x 241.3mm).The
optional rack mounting kit (A-LXP-R) handles one or two units in a single
rack space. Whatever mounting method you use, make sure that the LXP-
5issecurelyscrewedintotherackadapter–"frictionfit"ordouble-sticktape
installations may allow units to loosen during transportation, resulting in
damage.
The maximum ambient operating temperature is 35°C (95°F). Provide
adequate ventilation if the LXP-5 is mounted in a closed rack with heat-
producing equipment such as synthesizer modules, effects units, or power
amplifiers. Avoid mounting the LXP-5 directly above power amplifiers.

Audio Connections
This section outlines several connection possibilities for the LXP-5. Be-
cause each sound system is unique, we recommend experimentation to
arrive at the best configuration for your system. Always check connections
for proper impedance, polarity, and levels.
Audio connections to the LXP-5 are unbalanced, and should be made with
high quality shielded cables with 1/4" tip-sleeve phone jacks at the LXP-5
end. The connectors must be wired as shown below:
If only 1/4" tip-ring-sleeve phone jacks are available, they must be wired as
shown:
Sleeve - Shield/Ground
Tip - High
Sleeve - Shield/Ground
Tip - High
Ring - Connect to Sleeve
Mono or stereo?
The LXP-5 produces wonderful stereo effects from either mono or stereo
signal sources. For mono sources, use either of the two input connectors;
thedrysignal appears(alongwith thestereo effects)inmono atbothoutput
connectors. For instruments and sources with stereo outputs, use both
inputs.Werecommend using both LXP-5 outputs wheneverpossiblebut, if
monooutput is required,you canusejust oneof the twooutput connectors.
When only one output is used, the left and right signals are summed
internally .
Some of the examples on the following pages use stereo instruments and
amplificationsystems, othersuse mono.Feel free toadapt theexamples to
your specific requirements.

Connection to a mixing console's effects sends
If you will be using an LXP-5 as your primary effects unit, and your system
includes a console with one or more auxiliary (effects) sends, connect the
LXP-5 as shown above. In most applications, it is preferable to connect the
LXP-5 outputs to two of the console's input channel strips, panned full left
and right, rather than the effects returns. This allows the greatest flexibility
in routing and equalization.
Inthisconfigurationtheconsolecontrolsareusedtosettheamountofeffect

100% wet.
