Cloud Electronics CX163 - Manual (Page 10)

The RL-1A is available for the American market. The operation of the RL-1A is identical to the
RL-1 but it has been designed to fit a single gang US electrical outlet box. Front panel
dimensions are 4½” x 2¾”.
When setting the jumper(s) please ensure that you:
• Remove the mains cable from the rear of the product before removing the top
panel.
• Only reassemble the unit using screws identical to the original parts.
NOTE: The CX163 does not allow remote source selection, so it is incompatible with the RSL-6
remote wallplates.
5.3 Music Equalisation
Equalisation for the music signals treble and bass is provided via the rear panel pre-set controls
in order to allow the installer to tailor the response of the music signals to suit the acoustics and
speakers of each individual zone. The equalisation controls are located to the right of the Line
6 input and above the zone outputs; they are clearly marked ‘HF’ (High Frequency) and ‘LF’
(Low Frequency). A flat frequency response can be achieved by positioning the slots on the
control shafts in the horizontal plane; the HF control has a range of ±10dB at 10kHz and the LF
control has a range of ±10dB at 50Hz.
5.4 Line 6 Priority
In Zone 1, the line 6 music input
can be given priority over other
music signals. This is intended
for use with sources such as
jukeboxes or spot announcement
players. Priority is only enforced
when a signal is detected at line
6, at which point the selected
music source will mute, making
way for the line 6 signal. Once
the signal on line 6 ceases, the
selected music source in Zone 1
will smoothly restore to its former
level. The time taken for this
restoration can be 3, 6 or 12
seconds depending on the setting
of internal jumper J10; the factory
default restoration time is 3
seconds. In order to switch
priority on or off, the internal
jumpers J9a+b can be set. Both
jumpers will need to be set in the
same position; failing to do so will
result in only one of the stereo
audio channels being prioritised.
