on the top of the PentaClass speaker. Following are the various colors and the status they represent.
LIST OF SYSTEM STATUS INDICATION LIGHTS:
• None - PentaClass is turned OFF.
• Any color - PentaClass is tuned ON.
• White - indicates that the PentaClass settings are being reset or that it has just been plugged in to a power outlet but
is not yet turned ON.
• Green - default status indication that denotes the PentaClass is turned ON and the AUX channel is opened.
• Red - Indicates that the AUX channel is turned off. It is recommended that you close the AUX channel when the
PentaClass is connected to a long audio cable that produces a buzzing sound when the cable is not connected to an
audio source.
• Blue - The PentaClass is connected to a Bluetooth device and the AUX channel is turned Off.
• Orange - The microphone is connected to the PentaClass and the Aux channel is turned Off.
• Bright Blue - The PentaClass is connected to a Bluetooth device and the AUX channel is turned On.
• Yellow - The microphone is connected to the PentaClass and the Aux channel is turned On.
• Violet - Indicates that the PentaClass is receiving an IR, (Infrared), signal from the remote control unit.
• Blinking any colour - Mute function is activated.
There is also an Audio preset visual signal described on (› page 24).

Volume Adjustment
There are two methods of adjusting volume:
1
Primary PentaClass amplifier volume adjustment - this can be controlled by using the remote control or
microphone volume up and down buttons
2
Audio source and microphone volume adjustment - This can be controlled by the audio source device or the
microphone.
NOTE
• When the PentaClass amplifier exceeds 80% of it’s volume the bass is automatically decreased to prevent audio
distortion.
• It’s recommended you set your audio source volume to about 60% and then control the PentaClass's volume by using
the remote control.
• When the PentaClass is turned On for the first time, or after reconnecting to a power outlet, the volume resets to the
default level. Be careful to decrease your audio source volume level to prevent speaker damage before turning on
the PentaClass speaker.
• The PentaClass has DRC - Dynamic Range Compression which helps prevent the speaker from being damaged if the
music volume becomes too high.
CAUTION
Protect your hearing: Do not listen to the PentaClass at full volume for a long period of time.
Feedback Cancellation
For better performance it is recommended that you locate the PentaClass speaker as far away as possible from the
person using the microphone. If you get distracting feedback from the PentaClass speaker just reduce the microphone
volume. In some environments where loud sound near the person speaking is unavoidable it is recommended that you
use the optional unidirectional external over-the-ear microphone. This comfortable over-the-ear microphone can be
connected to your Runa microphone by plugging it into the 2.5mm audio input located at the bottom of your Runa
microphone. When the external microphone is being used the Runa serves as a tiny wireless microphone transceiver
and can be put conveniently into your pocket if you wish.

• Voice - tuned for voice frequency
• Music - tuned for music listening
• Bass - tuned to emphasize low frequencies
To indicate the active preset the PentaClass status indicator will flash a particular number of times to denote the chosen
preset when you are switching between presets:
• Multimedia x 1
• Music x 3
• Voice x 2
• Bass mode x 4

Installation
Determine Speaker Location
The PentaClass speaker has three options for installation:
Place it on the table.
Mount it on a wall.
Mount it on the ceiling.
The PentaClass speaker should be placed on a surface at least 0.7 meter, (2.5'), from the floor. Choose a location as far as
possible away from the speaker who will be using the microphone, (PentaClass ABM model). Choose a location with the
clearest direct line of sight, without obstacles such as furniture, walls, people, etc. between the PentaClass speaker and
the microphone for best performance. We recommend placing or mounting your PentaClass speaker in the middle of
the room where people are seated. If you like you can choose a location near the projector in order to share the same
power source.
