They can be a tad hissy these old series_5's, but my mate had one and the sound blew my newer mixer away. The image above shows a 16-8-2 with 3 additional 4 channel blocks added (you often find them sold with these extra channels) - So this board above is now a 28-8-2 board! ,p> Like all the Studiomaster series you get great amp's and Eq on the channels, this console features the usual 3 band EQ with swept mid and swept bass sections - you get 5 aux sends, with sends 1-3 being switchable between pre/post fade as a group.
Studiomaster 16-8-2 Studiomaster made great mixers right through the 1980's, and here's one that appears from time to time, the Series_5 - similar to the classic Studiomaster 16-8-2, but you could add-on extra mixer channel 'blocks' to this series.
