-What are two different cables that transmit audio and video at the same time through one cable? I have HDMI as one but i dont know the other.

HDMI and Coaxial (F-type)

-List three different types of video cables capable of transmitting a high definition signal.

HDMI, DVI, Component

-list two different types of digital audio cables. I think fiber optical is one but i dont know the other.

Coax (RCA), Toslink

-what is the purpose of hdmi?

Digital rights management, but that's not the answer they want. Say to allow one wire solution for hookup to the monitor.

-what type of cable is required to connect powered speakers to a computer? Would it be a 3.5mm mini cable?

Sure, unless your sound card has 5.1 analog out.

-What are some essential accessories needed for a home theater system? so far i have speaker stands and speaker cables. i need 3 more

Universal remote, HDMI, toslink, or RCA cables. TV wall mount, AV rack, banana plug tips, power center.

-a customer wants to purchase a dvd player but their tv only has coaxial input. what type of accessory would you sell the customer? i know what to get but i dont know the name of it.

I don't know.

-a customer walks into the store and decides to buy a flat panel tv for their home. what are the essential accessories needed for this setup. i have wall mounts and cables and i need two more.

Power center, HD cable or sat receiver.

-Name The Two Digital Surround for formats used on today's audio receivers?

I going to go with dolby digital and Neo 6. Confirm this, probably wrong.

-what is the main difference between these two formats?

Dolby digital plays the programmed source as it was recorded in DD. Neo 6 creates a simulated surround environment. Confirm this, too.

-What parts are required when purchasing a car head unit?

Wire harness adaptor, faceplate adaptor.

-what accessory is required when installing a car amplifier?

Amp kit, maybe a capacitor.

-how many pairs of speakers does the average vehicle have?

Two pair

Don't take my answers as gospel, but these would be my answers.

The quiz

For the customer with coaxial inputs only, you would need to sell them an RF Modulator

 

[mike c]

so you wanna be hired as a salesman?

-what is the purpose of hdmi?
a new terminology that will usher in a whole new set of items we can sell to customers: TV, Players, Receivers, same movies in a different format

-what type of cable is required to connect powered speakers to a computer?
That would be a MONSTER 3.5mm mini cable

-What are some essential accessories needed for a home theater system?
Bose Speakers, Bose Bass Module, Monster Cables, Monster Power conditioner, Movies to watch (down that aisle)

-a customer wants to purchase a dvd player but their tv only has coaxial input. what type of accessory would you sell the customer?
A new TV to go with the new DVD player


seriously though, these guys got your back

Name The Two Digital Surround for formats used on today's audio receivers and what is the main difference between these two formats?

Dolby Digital and DTS. The question as worded implies ONE main difference and I'd have to say the simple answer to that is: bitrate. The DTS bitrate is higher than DD which in general means that it is compressed slightly less than DD.

Isn't THX a digital surround format...?

It's nice to see Fry's employees are highly trained specialists

At least he went to the right place and didn't listen to the monster and bose "specialists"

They are both lossy formats. Compression is different issue. You will see compression on some CD music that have been graphically displayed here at AH.

 

[mtrycrafts]

Isn't THX a digital surround format...?

No. It is a technical standard to reproduce what was recorded in the studio, a standardization protocol.

 

[mtrycrafts]

Now that you have your answers free, all these good folks will get your employee discount as long as you work for Frys or another chain?

 

[MDS]

THX is many things and that is why it is confusing and often dismissed as a marketing gimmick when it really is not.

THX-EX is an encoding standard (6.1) and is the precursor to DD-EX. So in that context THX is a surround format.

But THX-EX and the THX post-processing routines (adaptive decorrelation, timbre matching, etc) can be applied to other formats as well. In that context, they are matrix decoders and not an actual format.

Then of course there are the THX performance guidelines that must be met for certification and they have nothing to do with surround formats.

You got some good answers, but you can take things a bit further I imagine... Let's elaborate some for fun.

-What are two different cables that transmit audio and video at the same time through one cable? I have HDMI as one but i dont know the other.

Coax? Check, but what about Firewire? For DV cameras and some DVD recorders, this can be used as well. Realistically, only one of these I believe puts the audio on the same wire as the video and that is coaxial. HDMI consists of something like 21 separate wires inside a single jacket... If I took RGBHV/Componet/S-Video/Composite, and bundled it with 5 stereo pairs, then ran it through snake skin - it may appear as 'one' cable, but it doesn't change that it is truly a bunch of different cables. Unlike coax which really is just a single cable carrying both audio and video.

-List three different types of video cables capable of transmitting a high definition signal.

HDMI, Component, DVI, RGB/VGA. It's important to know that the X-Box 360 only allows DVD upconversion over a VGA connection and not over component video, it also lacks a HDMI/DVI output. Good info for your customers - first ASK what they are trying to connect, then give them the right solution.

-list two different types of digital audio cables. I think fiber optical is one but i dont know the other.

The two types are coaxial and fiber. Toslink, or Toshiba Link is a set of protocols defining a digital transmission standard, but is most often associated with fiber cables. S/PDIF is the Sony / Philips Digital InterFace and is most often associated with coaxial digital audio. The two are fairly easily converted between each other if someone runs out of inputs on their receiver.

-what is the purpose of hdmi?

Definitely to simplify installation.
HDMI also delivers digital video and audio which means that it is less susceptible to interference and noise that regular analog video cables, like component video, can pick up. Lots of additional protocols are included within HDMI, but those two items are the biggest advantages for HDMI.

Biggest disadvantages for HDMI? Gotta be the distance limitation, though this is fading, and the inability to easily split/matrix HDMI to multiple locations.

-what type of cable is required to connect powered speakers to a computer? Would it be a 3.5mm mini cable?

Pretty much - remember 3.5mm = 1/8". Make sure that you are selling them a 1/8" STEREO cable - male to male. 1/8" stereo mini is often the term used.

-What are some essential accessories needed for a home theater system? so far i have speaker stands and speaker cables. i need 3 more

Speaker cabling to be considered different than interconnects which are also required, definitely a decent surge supressor/power conditioner, a decent equipment rack to hold everything would be nice, and definitely don't forget that universal remote. Heck, upsell them to a front projection setup and really start to accessorize!

-a customer wants to purchase a dvd player but their tv only has coaxial input. what type of accessory would you sell the customer? i know what to get but i dont know the name of it.

Properly stated before - RF Modulators will do the trick. The newer ones include inputs for cable TV and a local source. When it detects a signal from the DVD player it will automatically switch from the cable input source to the DVD input source to maintain the highest quality picture possible.

-a customer walks into the store and decides to buy a flat panel tv for their home. what are the essential accessories needed for this setup. i have wall mounts and cables and i need two more.

Similar to buying a home theater, you want surge supression, a decent remote... at a retail store? Don't ever forget the 'extended warranty'! You also want to make sure they have a DVD player and HD DSS receiver to deliver the best in content for their display.

-Name The Two Digital Surround for formats used on today's audio receivers?

This is pretty well covered in detail above - DD and DTS with DTS generally being considered better...

-what is the main difference between these two formats?

...because of the higher bitrate DTS offers.

~~~~~~~~~

I'll skip the car questions as they were pretty well answered to the best of my abilities already.

Questions that they didn't ask that you should really know the answers for are as follows:

1. What are the 5 different main television technologies on current digital displays?

2. What is the difference between them?

3. When should you use them?

4. What is the proper screen size for a 10'x12' room?

5. What is the difference between HD DVD and Blu-ray?

6. What do the power specifications on an A/V receiver mean?

7. What are ohms and why do they matter?

8. What are the different types of speakers?

9. How do you wire for a 7.1 audio setup?

10. Where is the proper placement for speakers in a 7.1 setup?

11. What does 5.1 and 7.1 even mean?

12. Why won't someone hear sound from their surround channels when watching TV, or listening to a CD? (most of the time)

13. Name 3 different ways to hide wiring.

Alex.... I'll take party speakers for 100 please.


The question.... "What is Bose?"

Bzz. I'm sorry but the answer was "party" speakers. The correct question was "What is Cerwin Vega?"
