Meet CTG Audio Microphones

CTG Audio manufactures high-performance microphones with a focus on ceiling based systems.

“These flush mounted microphones are unobtrusive (visible portion being smaller than a dime) and cables are hidden.”

CTG Audio systems allow participants to:

  • talk in a very natural tone and volume.
  • move around the room with no compromise in audio quality.
  • contribute without the passing around of a hand-held microphone.
  • identify who is talking at the distant end since the true timbre of the voice is being transmitted.
“The microphones are easily integrated with the current popular IP Video conferencing software such as: Skype, Zoom, Microsoft Team etc.”

CTG Audio systems are typically used for teleconferencing, presentation venues, distance learning, meetings that require recording, classrooms, courtrooms, etc.

“The table microphone can be plugged into a computer sound card to provide wide coverage of conference areas.”

All projector’s light sources have pros and cons

The primary light source technologies used in projectors are:
* Lamp
* Laser
* Laser-Hybrid

lamp is excellent for situations that demand high brightness and more accurate colors.
A lamp has very high luminous efficiency and high light emission.
A lamp is the optimal option to provide an accurate HDR result.
LED (Light Emitting Diodes) provides very good colors, low noise, low power consumption and less heat than other options.
LED is frequently used for portable projectors, even though the LED has limited projection brightness.

laser is the selected choice for large venues without sacrificing brightness, color saturation or image quality.
A laser provides high light output. The light travels in a straight beam with minimum divergence. The impact of the environment is minimal.
A laser offers maintenance free operation, lower heat generation and a non-standard angle mounting ability.
laser-hybrid is a combination of LED and laser technologies.
A laser-hybrid utilizes the advantages of LEDs. It boosts the brightness, but the color quality can be mediocre.
A laser-hybrid is maintenance free.
What is the right choice?
Each light source solution has advantages and disadvantages, depending on the application and the required functionality .
A few questions to consider to avoid buyer’s remorse and to ensure a happy customer:
  • How many hours the projector will be used every week?
  • What is the content that will be mostly displayed (text, images/movies or a mix of both)?
  • What is the required resolution?
  • Where will the projector be mounted? Bear in mind that regardless of which technology is selected, the projector’s filter must be cleaned at least once in a while.
  • How is the ambient lighting?
  • How many lumens should be considered?
  • How large is the projection screen?
  • What screen material will be used or is available?
  • What is the budget? 

Projection Screen Materials: Quick Reference

Several factors can affect the quality of a projected image on a screen:
* the projector
* the screen material
* the ambient light

The light in the room can really ruin the quality of a projected image.
It removes all the fine details.

Every projection screen manufacturer offers multiple finishes.
The right selection depends on various factors.

If the ambient light of the room can be controlled,
white smooth material finish is the preferred choice.
There are several white surfaces available with different gains and coatings.
If the goal is to project 4K images, consider the smother white material available

independent of the gain.The gain is dependent on the light output of the projector.

If the ambient light of the room cannot be controlled,
dark material finish should be considered.
There are multiple dark finishes available. A grey surface could be enough, but in

some cases, there is still too much ambient light,where an ALR (Ambient Light Rejection)
material would be a better option.

If the goal is to hear the sound coming from behind the screen surface,
an acoustically transparent woven material is the way to go.
Other options are perforated and micro perforated materials.
There are white and grey acoustically transparent material options.
The aforementioned criteria for choosing screen color
also applies to acoustically transparent material.

I have heard multiple times,
“I do not need a projection screen, I can project on the wall”
I disagree.
A painted wall will never be as smooth as it needs to be
to get the best projected image possible.

Resimercial where Residential Meets Commercial

The crossover between residential and commercial integrators is growing.

Many integrators have been forced to look into other types of projects.
This trend creates a larger client network,
generates additional opportunities and increases revenue.

This is the moment to explain and educate how products can be used in the two environments.

The residential clients work in offices,
own shops and bars and attend houses of worship.

The commercial clients have a residence.

While the goals are the same, every setting has its own set of requirements.

Integrators need to get educated.


Selling a High-End Product

High-End product is an extreme quality item.

No one likes to pay more when they could pay less, unless the product being offered creates the “WOW” factor and reflects IMPORTANT differentiation.

Customers will provide the information needed for us to close the sale.

Find out your competition.  Ask the customer about what other vendors they are considering.

Get rid of low-quality competitors as quickly as possible.  Convince your customer to eliminate poor quality options.

Check if the customer has experience buying highly priced solutions.  If yes, that is encouraging.  If not, explain the advantages of having a high-quality product.

Ask the customer if they have any stories when low-cost choices have let them down.  If the customer shares a story, use it to reinforce why to purchase high-quality products.  Bear in mind that if the customer is buying on price alone, it will be very difficult to convince otherwise.

Share examples of customers who have regretted buying a less pricey / less quality option.  If you do not have a story do not invent one.  If you have a story, then run with it!

Talk about the product, not all the add-ons you can offer – It is not about you!  The customer wants the best product for their money.

Provide price only after you are in control.  Never offer a discount unless you know for sure that your company is “winning” in the customer’s mind.  Make it clear that price negotiation will only start after the customer is really considering your proposal.

Never feel that you have lost the deal!

The deal is still on until it is off!
