Night club system with Tesira and Community audio
This system design template shows how Tesira and Community audio products can be used in a sound system for a small to medium sized night club.
System Design
This system consists of a Tesira DSP, configured to be used as a loudspeaker management system and Tesira amplifiers to power up the loudspeakers.
The main dance floor loudspeaker system consists of a pair of 12 inch 2 way loudspeakers configured as the Mid-High component of the system and driven two-way active. And two 18 inch subwoofer pairs to drive the lows. The subwoofers are configured as a cardoid subs pair, stacked vertically with the upper sub firing rearwards.
Additional side fill loudspeakers are provided to cover areas around the dance floor. Quantities could vary based on the layout of the venue.
Equipment List
Below is the list of Biamp and Community audio equipment used in this project:
- 1 - TesiraFORTÉ AVB AI 12 mic/line level inputs; 8 mic/line level outputs with integrated USB audio
- 1 - Tesira TEC-1 Tesira PoE Ethernet control device: in-wall/surface mount.
- 3 - TesiraXEL 1200.2 AVB enabled digital networked four-channel amplifier. 2 x 1200 watts power banks and 100% asymmetrical loading per power bank
- 1 Tesira AMP-4350R AVB enabled digital networked four-channel amplifier at 350 watts per channel
- 1 - PH POE36U-1AT-R Gigabit PoE+ Injector, IEEE802.3af compliant, IEEE802.3at, PoE capable network switch, or equivalent PoE injector
- 2 - IP8-1122-96 12-inch Two-Way Installation Loudspeaker, Nominal Beamwidth (H x V): 90° x 60°. 43 Hz – 22.4 kHz. 123 dB max SPL
- 4 - IS6-118 18-inch subwoofer. 32 Hz – 145 Hz . 132 dB max SPL.
- 4 - IC6-1082-96 8-inch Two-Way Installation Loudspeaker,, Nominal Beamwidth (H x V): 90° x 60°. 52 Hz – 19.5 kHz. 118 dB max SPL
Note that other non- Biamp/Community audio equipment is required to complete the system. this would include the mixing console/DJ mixer, booth monitors.
Example File
The example file for this system is configured for ...
- Source inputs from a mixing console and from a software based DJ console via USB. Source selection for the same is provided and can be controlled using the TEC-1 control interface.
- Parametric equalizers to tune the individual loudspeakers to the room and the source signals.
- Pass filters (low and high), to set crossover frequency and low frequency limit of the loudspeakers.
- Delays to time align the loudspeakers for proper acoustic summation.
- Recommended processing blocks for the Community loudspeakers. These blocks can be found in the processing library. Note that, the recommended processing blocks in this example file have been edited to suit this system and to fit into the available DSP recourses of the TesiraForte AVB AI.
- The cardoid processing section includes a parametric equalizer an all-pass filter, a delay and an invert. This processing is applied to the signal going to the subwoofer that is firing rearwards. The delay is used to time align the rear firing sub with the forward firing sub and the invert (along with the delay) to create the cardoid pattern. The parametric and the all pass filter are optional, but can be tweaked to fine tune the cardoid pattern.
- Output to side fill speaker and booth monitor
- an option to record the session via USB
The file's Equipment Table is populated with proper hardware to match the layout, but will need to have serial numbers and proxy host assignments added before loading the file to system. Click on the link below to download the file.

Audio Setup
The recommended system commissioning process.
- Equalize individual Speaker boxes to the room.
- Set the desired crossover frequency. This is currently set to 95Hz, on the example file
- Set the delays to time align the IP8-1122-96 and the IS6-118 pair.
- Tweak the delay on the cardoid processing block to achieve maximum SPL at the front. This is currently set to 2.06msec (28 inches/708mm). Note: to create a cardoid pattern the rear- firing subwoofer is required to be delayed by the distance to the front firing subwoofer and it's polarity inverted.
- And finally set levels and peak limiter thresholds for the desired SPL.
