On Christmas Eve 1923, 30^th US President Calvin Coolidge walked from the White House to the Ellipse and pushed a single button to light a 48ft Balsam fir – the nation’s first National Christmas Tree. On 28 November 2018, however, there were a few more buttons to push.

Monitor engineer Sven Giersmann piloted a DiGiCo SD10 console provided by Maryland Sound – the event’s audio supplier for more than a decade – serving the large and diverse array of musicians who performed at this year’s lighting of the National Christmas Tree. Hosted by actor Antonio Sabàto Jr and aired on the Ovation and Reelz channels the following Sunday, the 96^th annual production featured a line-up that included Abby Anderson, Anthony Kearns, the Dominican Sisters of Mary (Caroling Angels), Gabby Barrett, John Driskell Hopkins and Joe Gransden, Locash, Matthew West, Paul Cardall, Spensha Baker, Thompson Square, and the United States Army Band, ‘Pershing’s Own’.

‘The show has multiple performance spaces and is live to tape, so there was a lot to manage,’ says Matt Snyder, Maryland Sound’s Account Executive on site. ‘Some of the artists performed on their own, others played with the US Army Band, plus we had a number of different hosts on stage throughout the event, and we had a constant mix of both in-ears and wedge monitors. The SD10 was maxed out, but it handled everything flawlessly.’

The SD10 was used in conjunction with a pair of SD-Racks on an optical loop, clocked at 96kHz, to manage 34 handheld wireless microphones, 20 stereo IEM systems, and even more floor mixes. In addition to 96 stage inputs, multiple stems and truck feeds to performers were routed through the SD10 monitor console.

‘None of the small-format consoles in our inventory could handle the I/O capacity of this show,’ Snyder adds. ‘The SD10’s intuitive workflow was critical and, because of the remote location of the console, the iPad app was also an essential system tool. With only one timed rehearsal before the broadcast, Sven had to generate and edit snapshots on the fly, and the SD console software lets us do that easily.’
