IUT draws on AV to advance learning


A major audio installation has been carried out at the INHA University of Tashkent (IUT) in Uzbekistan. Carried out by Polymedia-Uzbekistan, the local representative for Russian systems integrator Polymedia, the project has seen a Dante network interface with an Extron GVE platform for campus-wide AV system management and monitoring via touchscreens. Polymedia-Uzbekistan was selected to deliver a high-specification, fully networked AV solution that included modern multimedia tools to facilitate distance learning. A key part of the project, Yamaha sound reinforcement systems have been installed in 12 lecture rooms and laboratories. Founded in 2014 and opened last year, IUT is a collaboration between the INHA University of Korea and the government of Uzbekistan with the intention of being the ‘most innovative and technically-developed educational institution in the Central Asia’.

A multi-zone system has been designed by Polymedia-Uzbekistan to ensure the clearest sound for every student in each room, in addition to having the ability to combine into a single, bi-directional environment. Supplied and installed by Uzbek installer ShowPro, Yamaha VXC8 ceiling speakers and VXS8 surface-mount speakers are used throughout, with multichannel XMV series Dante model power amplifiers. These can operate simultaneously in both high- and low-impedance, allowing connectivity of both speaker types without affecting the number of available output channels or the audio quality. In each space, a Yamaha MRX7-D matrix processor is used to manage the audio system, using its onboard parametric EQ, dynamic feedback suppression, Dan Dugan automixing, matrix mixer, speaker processing and delay to deliver optimum sound.

The most visible of the facilities is the university’s Room 303 lecture theatre, and the control room which overlooks it. This multi-purpose space is used to host a wide range of events and features and is equipped with a Yamaha QL5 digital mixing console – with MY4-AEC Acoustic Echo Canceller and MY8-LAKE Lake Processing cards – in addition to a Rio1608-D I/O rack in the control room with the MRX7-D. Another Rio1608-D is provided on the stage for local I/O, while six pairs of VXC8W ceiling speakers are installed above the auditorium and powered by an XMV8280-D multichannel amplifier. Lectures and smaller events can be managed by the MRX7-D’s Dan Dugan automixing and relayed via the VXC8Ws, while bigger events are mixed on the QL5 console to installed line arrays, which can be reinforced by the Yamaha ceiling speakers.

The 12 smaller lecture rooms and laboratories vary in size and layout, however each system features an MRX7-D processor, an XMV8280-D power amplifier, a DCP4V4S controller, DCH8 digital controller hub, a pair of VXS8W surface-mount speakers and from two - 12 VXC8W ceiling speakers. Audio inputs in each room come from a lectern microphone, two wireless microphones, an Aux input for extra local sources and the Extron system, for remotely-streamed content from INHA University of Korea.

The system designs were assisted by the manufacturer’s Commercial Installation Solutions Speaker Calculator (CISSCA) software, which helped ShowPro to create optimal Yamaha speaker systems. ‘The brief was to provide the learning spaces with audio systems that would take into account the different designs and acoustic characteristics of each room, deliver a uniform sound field and ensure that every student experiences equally high quality audio,’ explained Ilshat Kallimulin, ShowPro’s main project engineer who designed and implemented the system. ‘We are very pleased that Yamaha audio systems are helping IUT to enhance education and the improvement of society in Uzbekistan.’

Muzaffar Djalalov, acting rector of INHA University in Tashkent, added: ‘The system is very easy to use via the DCP wall panels and Extron touchscreens. The sound for any type of presentation is excellent, while the Dan Dugan automixing makes a big difference in only needing to have a sound engineer on duty for bigger events in the main lecture hall.’
