already implemented in Lok Sabha Sound System.

Advantage over the
Imported Equipments
• Distance from the speaking person to the microphone-2 feet (max).
• Delegate unit replacement in 2 minutes time when the system is in
offline.
• No programming of Delegate Units is required.
• Inter connection of Delegate Units by 1mm terminal silver pins and
loop cable by 9 pin D type connectors.
• If microphone is mishandled, it will still work properly.
• All equipments with plug-in module facility.
• All equipments PCB‘s with minimum 0.4 mm copper track
thickness.
• All equipments with virtual service kit facility for immediate
rectification.
• Equipments like Delegate units, SG unit, Chairman unit, Language
selectors, Interpreter units are designed in such a way that there is
no modification in the existing wooden furniture.

• SI (Simultaneous Interpretation System) functionality is monitored by
the Data Time Log System.
• IRD (Individual Result Display System), TRD (Total Result Display
System) and LSHD (Large Hall Display System) are all solid state
design from safety point of view in the chamber.
• Digital recording facility with time overlap suitable for Reporters.
• Functionality of the entire control equipments by LED‘s visual
indication.
• Number of loop cables are very less.
• All the components in the control system equipments are easily
available in the market.
• All equipments are indigenously developed to meet the Indian
custom built environment.
• No SMD (surface mount component) components.
• No special tool is required for servicing of equipment.
• Cables are manufactured in such a way that there can be no pest-
infestation.

• Single cable technology - Full system with A10 Cable.
• All the equipments can withstand all types of voltage fluctuation.
• Technicians who have assembled, wired and tested the
equipments are available during the running session for
maintenance.
• Specialist who designed the system is available during sensitive
electronic voting.
• Maintenance charge is very low.
• Voting Free - option from SG‘s unit.
• Solid State Digital Geographic keyboard with special functional
keys for easy operation.
• 575 microphones cannot be operated by touch screen monitor when
more than 20 microphones need to be switched ―ON‖ at different
location of the chamber at the same time.
• Stand-by sound system of the Lok Sabha is also operated by the
geographic keyboard.
• Virus cannot attack the system computer.
• Processor speed 2.8 GHz.

• System boot time 15 seconds.
• The system can be operated with Windows 98/ XP / 7 /8.
• Proven record of 15 years old for analog and digital Service centre
in 12 km distance.
• Since all control equipments from a single company, matching is not
a problem.
• Indian equipments for Indian Parliament.
• The low level speakers which are in front of the members act as re-
enforced sound systems for the main as well as the stand-by
system.
• The audio chamber is distributed through 5 DDPS, hence, in case of
a failure of any row, the front and the back row microphones can be
switched on with negligible time lag and will be unnoticeable.
• Digital voting system with solid state real time display is fully
functional only in Indian parliament.

• High-end professional conference system for any sensitive
installation in India is always accompanied by highly reliable Ahuja
dynamic microphone, but since our systems are reliable, no such
addition is incorporated.
• 575 microphones are distributed through 8 numbers of zero ohm
amplifiers, hence the total 24 microphones can be put ON without
any noticeable difference in audio level/quality.
• Microphone management system, simultaneous interpretation
system and voting system are all independent. Low level sound re-
enforcement system speakers are driven by a separate power
amplifier, hence the speaker system is also independent of the
above three systems.
• During the running session, serviceability below the chamber is not
permissible , hence our system doesn‘t use any active electronic
equipment below the chamber, which could cause any disturbance.

• Our special SMPS PSU-100 has a unique current sensing circuit,
suitable for Indian power fluctuations.
• During short-circuit or humid environment, it shuts down the power
mosfet driver and prevents smoke and fire inside the chamber.
• SI system with four languages is switched through 100 matrix
switches and low level speakers with 25 matrix switches to isolate
the faulty loop.
• SI with 8 language interpretation system is working without any
special software.
• In a running session, the Speaker can mute his/her microphones
when there is a verbal communication with the Secretary General or
the Marshal.
• Voting cycle can be initiated from 2 places, either from the Secretary
General Unit or from system computer in the sound control room. In
case of failure of the Secretary General unit, the voting can be
initialed from the sound control room.

• In case the main audio processor or main SI unit or main sound
system or main interpreter system fails it goes to standby processor
by flick of an A/M switch.
• In case the main Digital Processor or Digital Display Unit or main
system computer fails, it goes to the hot Standby Unit automatically.
• Many improvements are possible in the existing system and demo is
available.
• 24 microphones in the chamber can be switched ―ON‖ at a time.
• Sound clarity in the chamber can be improved by 3dB app by using
the same chairman mic capsule to delegate mics.
• Since the audio bus is separate, failure/short of digital bus will not
affect the microphone management system.
• The service time for the chamber in the morning is 1 hr (max), the
present ―audio test ― in front of the microphone is the best option.
• Original audio is reproduced.

• Record of 48 hrs of non-stop operation with electronic voting at
the end.
• Voting result can be printed out using a laser printer in one minute
with result of 50 members in one page.
• Press and Visitor‘s gallery uses cost-effective, reliable heavy duty
language selectors.
• No wall mounted or line array column speaker in the chamber,
hence the chamber aesthetic is not disturbed.
• No failure reported even when the electric power supply along with
UPS failed 14 times since installation.
• We have set standard for Lok Sabha, Rajya Sabha and Vidhan
Sabha.
• Maintenance without spare equipments for over 15 years, based
on confidence in our products.
• Saved crores of rupees for the past 10 years.
• Can save public money @ Rs.1 crore per year.
