About the battery protect circuit
The automatic battery protection circuit turns the unit off
when the battery approaches its ‘critical discharge point’ to
prevent damaging the battery.
When the Battery LED begins flashing, this indicates the
battery is low and the unit will shut off in 15 -30 minutes.
Expected service time from the battery
The service time per charge will vary depending on the
volume level, type of program usage and whether a
companion speaker is used with the system.
Service time per charge (speech input).
medium volume
8 to 12 hours
full volume (before clipping)
3 to 6 hours
Charging the battery
Plug the RC-16 charger (RC-16/220 for export) into an AC
outlet and into the charger input (the Charger LED will light,
indicating the battery is being charged). The charger will
automatically charge the battery for optimum recovery.
When the battery is charged (about 8 hours), the Charger
LED will flash. This indicates the charger has switched to the
maintenance charge rate—the charger may be left plugged in
to maintain a full charge without damaging the battery.
IMPORTANT: For longer battery life, always store the unit
with the battery in a fully charged condition or with the
charger plugged in.

Operation

Mic 1 Input
An unbalanced, low impedance microphone input. For use
with the Mic-50 supplied with your unit (except PB-35W),
or any mic with a 1/4" phone plug which does not require
phantom power.
Mic 2 Input
An unbalanced, low impedance microphone input (except
for model PB-35W; see below). For use with the Mic-50
supplied with your unit, or any mic with a 1/4" phone plug
which does not require phantom power.
On PB-35W (wireless) models, the built-in receiver is
connected to this input. Use the Mic 2 control to adjust the
wireless mic volume. (Inserting a plug into the Mic 2 input
disconnects the wireless input—to use a wired and wireless mic
simultaneously, plug the wired mic into the Mic 1 Input.)
Line Input
The line input (1/4"-phone jack) is used for playback of a
tape player, musical instrument or similar source. It may
be used simultaneously with the mic inputs for a composite
output.
Note: All connections must be made with shielded cable to
avoid hum, buzzing, or radio interference.
Line Output
The output signal is a composite of all the inputs. Use it to
record your presentation, or to “daisy chain” another powered
sound system to the MegaVox for greater crowd coverage.
Speaker Output
Use the speaker output to drive Anchor’s model P-351
companion speaker (in addition to MegaVox's built-in
speakers) for greater output.

OTE
: When an external speaker is powered by the MegaVox,
battery service per charge will decrease considerably.
