INTRODUCTION & CONTENTS

Congratulations on choosing Australian Monitor for your professional amplification requirements.

The Australian Monitor PICOBLU is a small form factor 30W Mixer Amplifier specifically designed for small space applications such as cafes, restaurants, small retail and classrooms.

The PICOBLU features 3 mixer channels with microphone, line level, Bluetooth® and 3.5mm input jack options.

WARNING

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT USE THE PLUG WITH AN EXTENSION CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE.

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

TO PREVENT ELECTRICAL SHOCK, MATCH WIDE BLADE PLUG TO WIDE SLOT & FULLY INSERT.

CAUTION
THESE SERVICING INSTRUCTIONS ARE FOR USE BY QUALIFIED SERVICE PERSONNEL ONLY. TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT PERFORM ANY SERVICING OTHER THAN THAT
CONTAINED IN THE OPERATING INSTRUCTIONS UNLESS YOU ARE QUALIFIED TO DO SO.

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

WARNING

TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance

For European Union countries: This symbol on the product or its packaging indicates that this product must not be disposed of with other waste.

PICOBLU BLOCK DIAGRAM

FRONT PANEL

1. CH 1-3
   These control the levels for each channel input.

2. BASS
   There is 12dB of cut and boost at 100Hz.

3. TREBLE
   There is 9dB of cut and boost at 10kHz.

4. SIGNAL
   This LED indicates the unit is outputting a signal.

5. POWER
   This LED indicates the unit is on.

6. POWER SWITCH
   This switches the power to the unit on and off. The up position is on.

7. BLUETOOTH®
   Consult the Bluetooth®
   Audio Streaming section of this manual for further details of these controls.

8. INPUT 2
   Input 2 is an auxiliary line input. Its volume is controlled by the CH2 volume knob on the front.

REAR PANEL

1. CH 1
   XLR input – This is a balanced microphone input with an input sensitivity of 3mV.
   RCA input – This is an unbalanced line level input. It has an input sensitivity of 405mV. The two RCA sockets are summed to mono internally.

2. CH 2-3
   RCA Input: These are unbalanced line level inputs. They have an input sensitivity of 405mV. The two RCA sockets are summed to mono internally.
   CH2 RCA input is mixed with the 3.5mm front panel auxillary input.
   CH3 RCA input is mixed with the Bluetooth® input.

3. LINE OUTPUT
   The LINE output is on an unbalanced RCA connector. The output level is 766mV with an output impedance of 4.7kΩ at the rated output.
   The mono output signal is split across two RCA outputs.

4. SPEAKER OUTPUT
   The class AB amplifier output features 100V Line or 4Ω low impedance.
   NOTE: Only one output type should be used at a time.

5. MUTE INPUT
   To enable CH1 priority (i.e., mute CH2 & CH3), connect the two contacts together with the mute illustration on the speaker terminal block

6. MAINS INPUT CONNECTOR
   Your amplifier is fitted with a standard IEC 60320-C14 socket for mains connection. Use the mains cable supplied to power up the unit.
   NOTE: Your unit must always be earthed!

INSTALLATION

LINE OUTPUT

The LINE output RCA can be used to connect up to 3 booster amplifiers.

INPUT CONNECTIONS

For wiring balanced in, pin 2 is hot. Unbalanced wiring on the microphone inputs is not recommended.
Balanced input wiring (shielded pair cable) is recommended. Unbalanced RCA wiring should be keep as short as possible

PAGING SOLUTION

The PICOBLU can be configured to provide a paging solution for small installations. Simply connect a paging microphone to CH1 XLR input and connect the contact closure output of the paging microphone to the PICOBLU mute terminals as shown below:

BLUETOOTH® AUDIO STREAMING

The mixer amplifier includes a Bluetooth®
Audio streaming interface which can receive audio from any device like a mobile phone, computer or tablet. Simply connect your Bluetooth® device and it will mix in to the amplifier output.

BLUETOOTH® CONNECTION

1. Turn on the Bluetooth® module by holding the Bluetooth® ON/OFF power button down for more than 150ms

2. Enter pairing mode by holding the Bluetooth® ON/OFF button down for 2 seconds. The PAIR LED should start flashing every 200ms

3. On your Bluetooth®device, not the PICOBLU, select the Bluetooth®
   device named as ‘AUS MONITOR’. Consult the device’s manual about accessing the Bluetooth® connection options.

4. Your Bluetooth® device will ask for a passcode/PIN. Enter 2626

5. The PAIR LED will then flash 10 times to indicate successful pairing

6. Play audio from your Bluetooth® device.

BLUETOOTH® CONNECTION RANGE
The Bluetooth® connection range is a minimum of 10 meters. However, range is typically much larger but not guaranteed.

CONNECTING A DIFFERENT BLUETOOTH® DEVICE

The Bluetooth® module can only support one device connection at a time.
If you need to change devices, repeat the Bluetooth® connection process described above. By entering pairing mode it disconnects the current device and allows a new device to be connected.

POWER OFF THE BLUETOOTH® DEVICE

To power off the Bluetooth® module hold down the Bluetooth® ON/OFF button until the PAIR LED turns fully on (not flashing) and then release the button.

IMPORTANT: Ensure that the volume of your Bluetooth® device is set to an appropriate level as this effectively adds in another volume control to your system.

NOTE: The Bluetooth® module is powered off as standard when turning the amplifier on to maximise security. If the amplifier is power cycled you must turn the Bluetooth® module back on by pressing the Bluetooth® ON/ OFF button.

TROUBLESHOOTING

Check power supply is connected

Distorted sound| Input is overloaded| Reduce input level at source
Output is being over driven| Reduce volume levels on front panel
Bass control is turned up| Reduce Bass control level
No sound but amplifier is on| Volume controls down| Check volume controls
No sound from channels 2 and 3| Priority function is being used| Disconnect mute connection on speaker output terminals.
