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.

Audio Presets

This function allows you to select pre-equalized audio settings. The PentaClass has 4 audio presets for various usage scenarios and better sound performance:

• Multimedia - is the default preset tuned for multimedia as such as videos or movies
  • 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.

NOTE

Place the PentaClass speaker away from direct heat, high humidity or physical obstructions. Do not place the speaker near a projector exhaust port or fan. The hot air from the projector can cause overheating and failure of your PentaClass speaker.
