19. Stereo Main Outputs
Unbalanced RCA connectors controlled by the master fader.
20. Line Inputs
Unbalanced RCA jacks for connecting to stereo audio from line level sources such as a CD-Player or
Mini-Disc.
21. Phono Inputs
Use these connections for turntables only. When these connectors are used the signal is fed directly
to the high quality RIAA phono pre-amplifiers. Connecting a line level source will overload the
sensitive phono pre-amps and cause distortion.
22. Ground
This is for turntable connection. Always use this connection when using turntables with a ground
cable to remove earth hum.

Your Guarantee of Satisfaction
Notes:
This product is guaranteed to the original purchaser against defects in material and
workmanship for one year from the date of initial purchase. Activate this guarantee at the time
of purchase by returning the Guarantee Card to the address below. Keep a copy of your sales
receipt for proof of guarantee status, should it be necessary.
The crossfader itself is a replaceable part and is only guaranteed against defective
workmanship. The slider selected for the crossfader function has been chosen for its excellent
mechanical properties. In a discotheque application the extensive use of this facility means
that the number of operations in a twelve-month period can exceed the manufactures
electrical specification.
If a malfunction occurs, the dealer who supplied the unit will be happy to handle the repair.
When returning a unit, use the original factory carton - do not chance inadequate packing
materials. Simply tape a note to the unit describing the malfunction.
If your unit is out of guarantee, we recommend that you return it to an authorised Citronic
dealer for repair or service. Experienced personnel, supported by specialist testing equipment,
will be able to find and correct the fault in the most efficient and cost-effective way.
