Quick Use Guide
Thank you for choosing an Anchor Audio portable sound system. Our products

you have shown by selecting an Anchor system.

David Jacobs, President on behalf of all Anchor employees
MiniVox is a battery-operated handheld P.A. system that’s
easy to set-up and operate. Before using the MiniVox, you’ll
need to install the batteries as described on page 4.
If your unit is equipped with an RC-25 rechargeable battery kit,
you must charge the batteries completely before use (see page 6).
Here’s how easy it is to use:
1. Set the MiniVox in front of your audience.
2. Plug a microphone into the INPUT jack.
3. Turn the MiniVox power/volume control ON (the red
LED should begin flashing). Then turn the microphone
switch ON. Adjust the volume control until desired
volume is reached.
To operate the wireless mic system on model PB-25W see
“Wireless Operation” on pages 7 and 8. For complete usage
instructions, see the “Operation” section beginning on page 5
(see page 6 for instructions on using the signal alert option.)
To avoid
feedback, do not
position the
microphone in
front of the
speaker.

Replacing the transmitter battery
Note: The transmitter power switch must be in the OFF position!
HANDHELD: Unscrew the battery compartment cover on
the lower end of microphone. Install a fresh ‘AA’ alkaline
battery and replace the cover.
BODY-PACK: Open battery cover
on the side of the transmitter box
and insert a fresh 9 Volt alkaline
battery. Close the cover.
Operating the wireless microphone system
1. Set the MiniVox down and direct toward audience.
(Position the MiniVox in front of you while using the
wireless microphone to avoid feedback.)
2. Turn the MiniVox power/volume control ON about
halfway (red LED should begin flashing).
3. Turn the wireless microphone ON as follows:
Handheld: Set the switch to the top ON position and
begin speaking. The middle STANDBY position
functions as a mute switch.
CollarMic, Headband or Lapel Mic: Plug mic cable
into transmitter. Set power/frequency switch to the
frequency of the receiver (either F1 or F2) and begin
speaking.
NOTE: When the mic/transmitter is turned ON and
the transmitter frequency matches the receiver, the RF
Signal Indicator on the MiniVox should light steadily
(indicating signal is being received). If it does not light
steadily, review the instructions above and the
troubleshooting section on the back page.
4. Adjust volume control on MiniVox.
Caution: Harmful feedback may occur when walking in
front of a sound system or speaker with a wireless
microphone. Always point mic away from speakers.
Observe proper
polarity when

Using the RC-25 rechargeable battery kit
For applications where the MiniVox is used frequently, the
RC-25 rechargeable battery kit is available. The kit includes
rechargeable batteries and an AC charging adapter. About
8-15 hours of operation can be expected per charge.
Using the RC-25 Recharge Kit
1. Install batteries as described on page 4.
2. Insert small plug on charger into CHARGER input on
the MiniVox and plug AC adapter into an outlet.
3. Note! Charge batteries for 24 hours before using
MiniVox for the first time. Typical charging time for
full recovery is 12-18 hours.
CAUTION: NEVER recharge other types of batteries.
Doing so can result in battery explosion. Use only
rechargeable Nickel Cadmium (NiCad) batteries.
4. Cycling the batteries: To extend battery life, we
recommend you fully charge the batteries once each
month during periods of infrequent use. Always
recharge batteries before storing.
Optional Signal Alert: Model PB-25SA
The Signal Alert button enables the MiniVox to produce a
siren-like tone. The momentary pushbutton switch on the
handle actuates the alert (the volume of the alert tone is not
affected by the MiniVox volume control).
Phantom Powered
Microphone Input
Use the phantom powered mic input (3.5mm jack) with electret
condenser microphones that require phantom power; such as
Anchor’s CM-1000 and HBM-35.
MICROPHONE
(PHANTOM POWER)
Recharge
batteries before
storing.
Do not charge
batteries for
more than 24
hours!
Setting up the wireless system
Set the frequency of the receiver.
The wireless receiver is mounted inside the MiniVox. and is
available with two different frequency pairs (this allows for
operation of up to 4 units simultaneously). A label on top of
the MiniVox indicates which 2 frequencies your system is
equipped with, and the desired frequency is selected via the
frequency switch.
1. Set the frequency of the receiver to either of the two
channels, F1 or F2.
If you experience ongoing interference problems with your
wireless system, the selected frequency may be incompatible
with other RF systems in your area. Try the other channel.
Set the frequency of the transmitter.
During use, make sure the transmitter you are using is set to
the same frequency as the receiver as set above.
HANDHELD: Set the frequency switch inside the
battery compartment to match the channel of the
receiver. Replace the cover—but don’t overtighten!
BODY-PACK: The power/frequency switch on the
transmitter determines the frequency. During use, set
the switch to match the frequency of the receiver.
