?
What mixers can CTG microphones be used with?

Any mixer providing 2-50 V DC phantom power will power CTG Microphones.

?
For large rooms (classrooms, briefing rooms, presentation rooms) can the CTG Systems provide for voice-lift?

Yes, this is generally done via zoning and appropriate layout of the microphones and speakers to avoid feedback.

?
Can the ceiling microphones be mounted in ceilings with other than ceiling tiles?

Yes, they are boundary microphones and may be flush mounted in any material.

?
Since the ceiling microphones are mounted in the ceiling will the presence of HVAC vents and fans have an impact on the sound quality?

Generally not as the microphones are flush to the ceiling and the air (warm or cold) does not flow directly over the microphone element. The elements in the CTG microphones are surrounded by silicone (thus floating) and do not transmit conductive noise from vibrating surfaces.

Also most of today mixers, including the ones offered by CTG, have noise suppression which will eliminate consistent noise such as HVAC fans or computer fans.

?
Do the table microphones perform in the same manner as the ceiling microphones?

The implant microphones use the table surface as the boundary and the elements are also “floating” to minimize table tapping noise.

The table top microphones are pre-mounted in a 5.75” disc but also couple with the table to extend the boundary.

?
How does CTG handle rooms that are extremely reverberant due to a lot of hard surfaces?

In very reverberant environments CTG would normally recommend acoustical treatment. This treatment usually consists of acoustical panels which are inexpensive and easy to install.
