 As long as the pitch control is in center “detent” click position, the turntable is operated at selected speed.
 The speed can be increased or decreased by 10% by the pitch control.
 An incorrect adjustment done on purpose can also be used to have the turntable rotate extremely slow or
fast.
 The strobe dots at the edge of the turntable are used for speed monitoring.
 Clean the stylus periodically with a soft brush to prevent the accumulation of dust.
 When sound becomes distorted or noisy, check the stylus. If the stylus is worn out, replace it with a new one.
 From time to time, the transparent dust cover and turntable cabinet should be wiped down with a soft, dry cloth.
 Volatile materials should not be used, such as: alcohol, thinner, benzine etc. They may remove the paint or
damage the luster.
1. 45-rpm Adaptor
This adapter allows you to play standard 7” EP vinyl
records with large center holes. Place the adapter

This ground connection is designed to reduce the
humming and popping noises associated with
magnetic phono cartridges. Be sure to connect the
turntable ground lead to any available ground
terminal on the same mixer the input signal leads
are connected to
24. RCA output Jacks
The output is able to switch to PHONO output or
LINE output. For example: These jacks are used
to send a low voltage "phono" level output signal
to a mixers "phono" input jacks. Turntables should
be connected to “Phono” inputs on a mixer. The
red colored RCA jack represents the right channel
input and the white represents the left channel
input.
