Dear all,
I'll start with Kedar's set-up as shown in post # 25 of this thread:
I have only contributed to the sound system part of this set-up.
The layout, design and even the installation of room, screen, projector and sound system is done by Kedar himself.
However, we did discuss a lot in detail. e.g. :
a. Distance of the first row from the screen
b. Height of the 2nd row chairs from the floor
c. height of center, surround speakers from floor
d. width of the screen, projector height and length
From the dimensions of the room and the kind of material he was going to use for interior, we agreed that I would help him with acoustics only if it is needed. If there is no echo, or if the room does not boom, we will keep it un-treated.
I have not, yet, been to Kedar's place yet. So I will take his word that the room be left un-treated.
Kedar is my first walk-in to have found me through the net!!
As with everyone, before a demo, I asked him for his detailed requirement and concluded that he needed a sound system to be used with a projector in a dedicated room and he did not need any media player with USB and Bluetooth. A Surround Sound System.
Before the demo I informed him (and his friend who accompanied him) that while almost all systems in the market need 5CH and above to surround you, My System needs only 2CH!! Its different, I know. But its practical, for most people and their requirements.
The System that I offered him:
1. Surround Sound Ampli-Decoder
2. 2.1CH Center-Surround-Subwoofer speaker set
Surround Sound Ampli-Decoder: It consists of:
i. A Digital Audio Processor based on SigmaDSP audio processor with its power supply
ii. A 2.1CH single board amplifier with its power supply
iii. A front panel with 4 potentiometers and one status LED
iv. A back panel with 2 x stereo analog inputs and 1 x SPDIF digital input that is jumper settable to select between optical input or co-axial input
2.1CH Center-Surround-Subwoofer speaker set:
i. Center speaker: One speaker that houses 2 x 3" Full range speakers
ii. Surround Speaker: Two speakers that each houses 1 x 3" Full range speakers
iii. Subwoofer: One sealed speaker that houses 1 x 8" subwoofer.
The wiring layout and speaker layout is as shown in the attached pdf.
The speaker layout in the center is used for demo and in Kedar's set-up.
Through a demo I prove all the tall claims that I make. The following is the list that also serves to highlight the features of the system:
1. Short circuit proof amplifiers!
2. System that can handle 190V to 265V mains supply variation. So no external stabilizer is needed!
3. During demo, passage from the movies is so selected that dialogues is followed by a song sequence. Here it is demonstrated that soft passages as well as loud passages are handled such that you don't have to change the volume. This is repeated for low, medium and high volume to demonstrate consistency in quality irrespective of the master volume setting!
4. Different sources are used. PC output, USB, Bluetooth (for music and songs) as well as STB to demonstrate that the system will produce good quality surround sound irrespective of the input source as long as it is stereo!
In summary, the customer is made aware of the quality, ease of use and cost without going into any technical details.
20Wrms/CH for room size of 400sq. ft., 80W/CH for large rooms, 160Wrms/CH for cinema theaters upto 650 seat capacity with appropriate speaker systems are used. Quality remains the same!
Above feature set is in its entirety is very unique and it requires a lot of guts to demonstrate it all in a single system in a single demo.
I promise them that it will sound the same in their houses, if not better and that it can be used by everyone in the house, not just the single geek, day in and day out, with any stereo content and not have to wait for a certain blu-ray with certain track configuration or a certain type of sound transmission.
My aim is not just to do business but to ensure that the customers money is well spent. I educate them and learn from them as needed.
I still need more time to reference the movie/ song clips to system behavior.
But let me know what you think so far.
@MaSh ,
@rikhav : I hope that this helps.
