Product overview

What to do when I receive my PicoMic kit?

Thank you for choosing a PicoGear product, we hope you will be satisfied!

Before you can use your wireless audio system, follow the procedure below:


Pair a microphone

You can pair a PicoMic as MIC1 or MIC2.

  1. Remove all microphones from the receiver’s charging dock.
  2. Select the number to which you want to assign your PicoMic (MIC1 or MIC2) using the up / down keys, then press OK
  3. A message appears; insert the microphone to be paired into the charging dock of the receiver.
    The location in the charging dock (top or bottom) does not matter and does not affect the choice of MIC1 or MIC2 microphone.
  4. Once the microphone is inserted in the charging dock, a new message appears: your PicoMic is now paired.

What if nothing happens?


Connect to a microphone

The connection is made automatically as soon as the PicoMic is removed from the charging dock of the receiver.
Obviously, your microphone must have been paired previously.

As soon as the microphone is placed back in the charging dock, the receiver disconnects from the microphone.

If you turn off the receiver while the microphones are not in the charging dock, the receiver will automatically disconnect from the microphones.
They do not consume energy and can remain dormant for several months.
As soon as the receiver is turned back on, it will automatically reconnect to the paired microphones.

The color of the microphone LED indicates its assignment at the receiver:


Mute a microphone

When a microphone is connected, you can mute it at any time.
To do this, select the microphone you want to mute (MIC1 or MIC2), and press OK to enter its configuration menu.

Select “MUTE ON”. The receiver then disconnects from the microphone, and its status is displayed on the main screen:

When the microphone is no longer connected, it consumes no more power and can remain in MUTE mode for several months.

When you want to reconnect to the microphone, return to its setup menu, and go MUTE to OFF.
The receiver will immediately reconnect to the microphone.


Adjust the microphone gain

PicoMic microphones feature a remote gain adjustment feature, so you can adjust the sensitivity of the remote microphone from the receiver.

To do this, select the microphone whose gain you want to adjust, and press OK to enter its setup menu.
Select the microphone gain between -18dB and +30dB.

Use the VU meter to adjust the gain.

The gain should be set so that the audio level on the meter is always included in this area:


Noise reduction

When high gains are used (between +18dB and +30dB), the microphone is extremely sensitive and a background noise may appear.
PicoMic microphones include a noise reduction algorithm to attenuate background noise when no speech is detected.


Built-in audio limiter

PicoMic microphones incorporate an audio limiting feature.

When the microphone detects that the audio level becomes very high compared to the chosen microphone gain (-6dBFS), it decreases the gain dynamically and extremely fast, so that the microphone never saturates.

This feature uses a so-called “look-ahead” algorithm which allows to obtain exceptional performances, with an almost inaudible change when the limiter is triggered.


Connection trigger

You can select between two connection trigger methods:

Use the DISTANCE method if you have problems with the DOCK method, and the PicoMic connect even when it is in the dock.


Audio output configuration

The PicoStream receiver supports two audio output modes:

The PicoMic receiver can work with both configurations.
By default, the audio output is in TRS (stereo) mode, but if the receiver detects that a smartphone is connected, it will automatically switch to TRRS (mono) mode.

The supplied audio cable allows operation in all configurations without cable change.

In case of problems, you can force the configuration in TRS or TRRS mode:

In most cases, we recommend staying in AUTO mode.

The current mode is shown on the main screen:


Audio output gain

The gain adjustment of the audio output is critical for good audio quality.
It is imperative to avoid having an output level that is too low, which would generate audible hiss noise on your recordings.

The audio output level setting depends only on the device you are connecting your PicoStream receiver to.
It does not depend on the ambient audio level, which should to be adjusted by changing the gain of the microphone.

To adjust the audio output level, we recommend the following procedure:



Audio output routing

For each possible mode (TRS or TRRS) you can set the desired effect for the output audio signals:

For each signal, you can assign either MIC1, MIC2 or a mix of the two MIC1+MIC2.


Charging & battery life

The PicoMic system runs on high capacity internal batteries.

You can expect the following battery duration:

Charge your PicoStream receiver

To charge your PicoStream receiver, use the supplied USB cable and connect it to any USB charger (wall charger, computer, power bank, etc.).

The receiver can be charged while being in operation. This is especially useful if you want to extend the battery life using a power-bank, for example.

Charge your PicoMic microphones

The microphones charge when they are placed in the PicoStream receiver’s magnetic charge dock.

The microphones charge only when the receiver is charging itself and its USB cable is connected to a power source.
The LED lights up in orange when charging is in progress, and turns off when charging is complete.
