SYSTEM OVERVIEW

1. Mic Inputs
Jubi speakers are design to accept microphone
level signals through XLR and 1/4" phone jacks
(for balanced or unbalanced signals). The level of
these inputs' signal can be adjusted using the mic
volume control.
2. Mic Volume Control
This control allows you to adjust the incoming sig-
nal from the mic input jacks. Setting them to the
left-most position (-∞ dB) will completely cut the in-
coming signal, whereas the right-most position will
add 10dB of boost to the signal.
3. Line Inputs
This balanced ¼" phone jack accepts line-level
signals from external devices. Stereo RCA connec-
tors are also included. The incoming signals from
2
these inputs can be adjusted using the line volume
control.
4. Line Volume Control
4
This control allows you to adjust the incoming
signal from the both the line input and RCA input
jacks. Setting them to the left-most position (-∞ dB)
will completely cut the incoming signals, whereas
6
the right-most position will add 10dB of boost to
the signals.
5. Line Output
The 1/4" phone jack line output will send the final
7
mix of the channel 1 and 2 input signals, allowing
the signals to be employed by additional speakers
or other devices. Do not under any circumstances
8
connect this output connector to the input of the
same unit. This will cause an audio loop at frequen-
cies and levels that will be extremely unpleasant.
6. Main Level Control
This rotary control will adjust the final output mix for
10 the Jubi JNR speakers.
7. Treble Control
This control gives the user control of high frequen-
cies (12kHz) in their audio. This allows for a total of
10 dB of boost or cut.
8. Bass Control
This control gives the user control of low frequen-
cies (80Hz) in their audio. This allows for a total of
10 dB of boost or cut.
9. AC Power Connector
The Jubi JNR speakers an AC power socket for
connection of the included AC power cable. Pho-
nic advises that the grounding pin of the connected
power cable should not be defeated for any rea-
son. This connector also features a fuse. In the
event the fuse blows, the cover should be removed
and the fuse replaced with another identical fuse.
Fuse details are listed above the connector.
10. Power Switch
This switch will turn the Jubi JNR speaker on and
off.
