Q: ロジャー テーブルマイクIIとその他のワイヤレスマイクとの違いはなんですか?

A: ロジャー テーブルマイクII は新世代のマイク技術によるマルチビームテクノロジーがすぐれていて、集団での会話の中で話し手が切り替わったとき、自動でその切り替わりを追い、聞き手にシームレスに話し手の声を届けることが出来ます。

その他の重要なポイント:

  • リモコンでのコントロールが可能なので離れた場所からの音量調整が簡単です。
  • 市場で販売されているほとんどの補聴器・人工内耳に対応可能です。
  • 周囲の騒音のレベル変化に自動で適応してくれるので、騒がしい環境下においても良好な音声理解を提供します。

Q: ロジャー テーブルマイクⅡはどんな補聴システムとも一緒に使えますか?

A: ロジャー テーブルマイクⅡの音声を補聴システムに取り込むために、ロジャーの受信機が必要です。は近年販売されているほとんどの補聴器、人工内耳(Baha含む)と一緒に対応可能な受信機があります。

Q: ロジャー テーブルマイクⅡは何人の人が同時に使えますか?

A: ロジャー テーブルマイクⅡに接続できる受信機の数には制限がありません。

Setup

Q: How do I need to setup the hearing aid?

A: Most HI / CI automatically switch the program when Roger Table Mic II is switched on. Some need a manual program (e.g. EXT / DAI or T-Coil)

Please check your HI / CI user manual / fitting guide.

Q: How do I connect Roger Table Mic II to the hearing aids / cochlear implant?

A: Hold Roger Table Mic II close to the receiver and briefly press the connect button, a green LED confirms connection. This only needs to be done once; Roger Table Mic II remains connected. A tone/beep is presented and should be heard as an auditive indication of connection.  

Technical questions

Q: What are the technical characteristics (operating time, range, latency of Roger Table Mic II)?

A: Operating time: Up to 16 hours
Range Roger Table Mic II to Roger receiver: Typically 20 meters / 60 feet, ideal conditions 40 meters / 120 feet
Latency: Mic to receiver output: 17 ms

Q: How many microphones are in Roger Table Mic II?

A: MultiBeam Technology utilizes three omnidirectional microphone elements arranged in an equilateral triangle. Each element in the array can act as either a front or rear element for either of the other two elements. The directional behavior then becomes equivalent to six directional microphones, creating a full 360° pattern. 

Q: What audio input options does Roger Table Mic II have?

A: Roger Table Mic II can be connected to a headphone output (3.5 mm socket) using the included audio cable.

Q: Can I combine it with other Roger microphones?

A: Yes. It is recommended to use Roger Table Mic II with other Roger Table Mic II or Roger Select for the best listening experience.

Q: How do I reset Roger Table Mic II?

A: Complete reset: Press On/Off and Connect together for 10 seconds

Disconnect (NewNet): Press Connect for 10 seconds

Q: How does the audio processing in Roger Table Mic II compare to Roger Table Mic?

A: Roger Table Mic II uses MultiBeam Technology to create beamformers in six directions. The beam with the best SNR will be selected continuously as different persons talk. MultiBeam Technology reduces reverberation and background noise significantly compared to Roger Table Mic (first gen.).

Q: How does the audio processing in Roger Table Mic II compare to Roger Select?

A: Roger Table Mic II uses the same MultiBeam Technology as Roger Select, but has a slightly lower kneepoint which allows it to pick up speech at a longer distance. Roger Table Mic II is calibrated against a maximum pick-up distance of 3m, whereas Select is calibrated against 1.2m.

Q: How does Roger Table Mic II treat the sound in a difficult sound environment with over 70dB SPL of noise?

A: The adaptive behavior increases the gain in the Roger receiver by up to 14 dB. Due to the possible SNR disadvantage of a far-field microphone care should be taken to avoid discomfort in environments with more than 65 dB SPL of noise.

Daily use

Q: What can clients do to improve understanding using Roger Table Mic II?

A:
  • Always bring Roger Table Mic II as close to the talkers as possible.
  • Avoid hiding Roger Table Mic II behind glasses, computer screens or other objects.
  • If possible make sure talkers are seated, as the beams in MultiBeam Technology are optimized for seated talkers.

Q: Is it possible to listen to a connected audio device and the microphone in parallel?

A: No, but several Roger Table Mic IIs can still be used in a MultiTalker Network. Any Roger Table Mic II not connected to an audio device will function as normal.

Q: How can Roger Table Mic II be connected with a phone?

A: Adaptors and cables can be used. Please check the ‘Phone calls made easy with Roger’ brochure. 

Q: Why is it not possible to manually select the active beams as on Roger Select?

A: Business meetings are generally a more controlled situation than social gatherings, and there is less need for manual control of the beams. If the user is disturbed by unrelated discussions or distant talking, the remote control can be used to reduce the pick-up range or mute the microphone completely.

Q: Is Roger Table Mic II ever in omni mode?

A: No, MultiBeam Technology is always active to give the optimum speech intelligibility in every situation.

Using multiple microphones

Q: How many other microphones can be connected with Roger Table Mic II?

A: Up to 10 Roger microphones can be connected in a network.

Q: What dictates which microphone should be active when more than one Roger Table Mic II is used?

A: Voice-activity-detection (VAD) according to the first-come, first-served principle. Note that the VAD is active also for the line input. This means that Roger Table Mic II can be used in a MultiTalker Network in for e.g. Skype meetings. One mic is then dedicated to Skype and the others for the local party.

Q: How fast is the switch between different talkers and microphones? Is there any risk of drop-outs?

A: The switching is instant and seamless. However, the speech might linger in the “wrong” microphone until the person talking pauses (takes a breath) because of how the VAD operates.
