*¹ Sensitivity is the lowest level that will produce an output of +4 dBu (1.23 V) or the nominal output level when the unit is set to maximum gain. (all faders and level controls are maximum position.)
*² XLR-3-31 type connectors with latch are balanced. (1=GND, 2=HOT, 3=COLD)
* In these specifications, 0 dBu = 0.775 Vrms.
* All input AD converters are 24bit linear, 128 times oversampling.
* +48V DC (phantom power) is supplied to INPUT (1-48 or 1-32), ST IN 1L-4R, OMNI IN 1-8 and TALKBACK XLR type connectors via each individual software controlled switches.

Installation Case

Costing over £60m, the new Prime Minister’s Office in Brunei is an opulent, state of the art venue which houses the central coordinating body for all of the sultanate’s government ministries and agencies. With a theatre and banqueting hall that each seat 1000, a 300-seat conference hall and 13 further conference and meeting rooms, Yamaha digital mixers and amplifiers deliver the requisite optimum audio quality.

Installation Case

London’s Queen Elizabeth II Conference Centre (QEIICC) is one of the UK’s leading corporate venues. Hosting over 400 meetings and events per year, its conference facilities have been significantly enhanced by the installation of a pair of DUGAN-MY16 automixing cards in Yamaha M7CL-48 digital mixing consoles.
