Level Adjustments & Input / Output Connection - Figure 6.
System inputs, outputs and levels can be controlled via this module. Master volume adjusts overall system level from
all inputs (ie: UHF, CD / MP3 player, RCA stereo input and wired microphones). Treble and bass controls effect all
system inputs. When set to half way, sound output will be flat.
RCA stereo jacks are provided for an external audio source. This allows connection of a CD player, iPod or other audio
source.
An RCA output is provided for use with external zone amplifiers or other PA systems if required. This output signal is
combined from all inputs (ie: UHF, CD / MP3 player, RCA stereo input and wired microphones).
If an external speaker is required, it can be connected to the portable PA system via 6.35mm jack. Note: this feature
is designed for 8 ohm minimum impedance speaker. Overall amplifier output will be split between both speakers when
in use.
