The New SPARK Mutli Purpose Hall AV System

This Multi Purpose Hall, as the name implies is used  for many things. When we first went to see the place it has an existing PA system. There was a TOA PA system installed in the place, which isn't bad if this was a small meeting room, a canteen or a fast food restaurant- unfortunately it wasn't. The place can sit seven hundred pax. So we went on to change the system and added a projector plus a projection screen.

Our boss had someone supply us the equipment, we, like most of the time had a design for it but then in the end we always end up installing some other equipment supplied to us which, needless to say, are not in our original list for the original design.

The main speakers were composed of two Danley GH60 and one Danley TH115. These speakers were driven by Danley/Crest Audio DSLA6.5Ks. One amp for the two GH60s and another one for the TH115. The floor monitors are extra speakers we pulled out form one of our venues, a pair of active db Technologies FLEXSYS FM12. The stage wasn't that big and a live band set up on there will be a rarity. A XILICA XP4080 manages the speakers. All signal cables run back to the temporary control booth located on the ledge/viewing gallery. Where a Presonus Studiolive24.4.2 will handle Inputs and outputs. This mixer will be more than enough to handle any event that will be held in the place.

A Panasonic PT-D6000US projector was installed for slides and presentation. The screen was a motorized Remaco XXL hung just above stage, there was no place else to put the big screen, it can't be installed at the rear of the stage as the ceiling of the stage was just as high as the screen height. For inputs going into the projector, we installed two video port on the stage and another port on the control booth. Each video/audio signals from the stage are sent to the switcher via Extron MTP T 15HD RS  transmitter/MTP RL15HDA receiver. From the MTPs the video signal goes into the Extron MVX  44VGA switcher, audio goes into the presonus mixer and video is then sent to the projector. Two pairs of Audio Technica ATW-R1200 receivers and three ATW-T220A
handheld transmitters and one ATW-T210a bodypack for the lapel wireless mic system was also patched into the mixer for announcements.

Lighting for the stage were a mixture of cheap spots, LED pars and profiles all from china. All of which are controlled via a Sunlight DMX interface connected to a laptop in the control booth.

All the equipment in the control booth are house in a 16RU flight with casters, front and back covers of the flight case serves as a table for the mixer during events.

Though we didn't get to put our original design into it, in the end, it turned out good. Functional and more than enough for the place.

SPARK Gym and Aerobics Room Sound System

A few months back we did an installation work on a gym and aerobics room. They wanted a system that runs separately but are on the same rack. The owner didn't want the rack to be in  a permanent location. So we put the equipment in a custom 20 RU flight case with caster wheels. They also wanted volume controls for each of the rooms.

The area where the gym and aerobics room is located is known for over voltage and that equipment don't last long without using power conditioners. Luckily, we ordered a few Furman CN3600 SE smart sequencer specifically for this issue so we installed them on the rack to protect the equipment.

The rack houses equipment for two different rooms with separate inputs and outputs.
The gym had three stereo inputs; a stereo input from a computer, a stereo input from media devices via mini-jack and an input from a TV decoder. All these inputs are routed via matrix, courtesy of a Xilica A1608 processor, to a Work PA5000 Amplifier powering six white Work Neo3 speakers on 100V line for the top end and two white Work Neo S8A active sub woofers for 150Hz and below via balanced cable. For the gym, the output from the processor is mono but we still used stereo connections on the inputs so as to be able to send both channel signals to the speakers  plus we have 16 input connections on this processor what's that many inputs for?
Each room have their separate input selector and volume control. The Xilica Mini K4 provides this.

The volume controls are connected to a switch with POE then to a router where the Xilica A1608 is connected. Using a POE switch saved us time during installation of the Mini K4s, without it we would've pulled electrical wire for their power supplies.

Work speakers at the gym 

The Aerobics room required a CD player with pitch control, for this we installed a Stanton C.502. Enough for their requirement. The player outputs goes into four inputs on the Xilica A1608. Also, they required a head-worn mic with body pack for the aerobics instructor, for these we installed an Audio Technica ATW-R1200 receiver with ATW-T210a transmitter which goes into the Xilica processor. A cable with mini-jack for Ipod, computer and devices was added inside the aerobics room which goes into two inputs on the processor.

All these inputs on the aerobics room are then sent to to two power amplifiers, two outputs goes to a Work Zenith 2400 powering 2 Work Mino10 loudspeakers and one output goes into Work Zenith 1300 which is bridged to power a Work Z15 subwoofer. The aerobics room has it's own Xilica Mini K4 volume control connected to the POE switch mentioned earlier. The two Work Mino 10s were surface mounted while the Z15 passive subwoofer is on the floor.

For the loudspeakers on the Aerobics room, Belden 1313A speaker wire is used to connect the loudspeakers to the amplifiers. For patch cables Canare L-2B2AT. For speakons, XLRs, mini TRS, and RCAs, Neutrik connectors are used.

The rack is currently located at the reception area, where it can be operated by the receptionist. Volume control of the sound system can also be controlled over Wi-Fi using IOS or Android application

So that is one job done in a few days. Images of the rooms with all the equipment will uploaded soon.
