11 TUBE ULTRAGAIN T1953 The LEVEL control The LEVEL control sets the signal gain at the input of the tube stage. Use this control to adapt the TUBE ULTRAGAIN to either home recording level (-10 dBV) or professional level (+4 dBu). When this level is too low the tube effect becomes less audible and t...

12 TUBE ULTRAGAIN T1953 3.2 The TUBE ULTRAGAIN as a level converter Semi-professional devices in hi-fi and home recording environments are usually operated with a nominal level of -10 dBV (0.316 V), while the level used in studios is 0 dBu (0.775 V) or +4 dBu (1.23 V). So, when you connect devices o...
