[. . . ] This feature saves a great deal of time, as in a matter of seconds the operator can flick through all the outboard settings on every channel, and make any necessary adjustments without leaving the console's central mixing position. There is also less chance of adjusting the wrong output's EQ by mistake. BACK PANEL CONNECTIONS Each monitor output has a fully balanced insert point, with sends and returns on separate 1/4" jacks. There are therefore 20 sets of jack sockets, designated 1-6, 7A thru 12B, L and R. There are also balanced XLRs for the main outputs and external inputs. INPUT STAGE The SM20's mic input stage uses identical circuitry to that developed for Soundcraft's highly successful Series FIVE front-of-house console, which in turn was developed in response to customer feedback. The external inputs feature is useful as a bus input when linking two consoles together. GROUPS TO L/R Another element of the SM20's flexibility is that it can be used as a front-of-house console if required. The GRP to L/R switches feed the monitor busses into the master L/R outputs (outputs 19 and 20), allowing you to manufacture a front-of-house mix. Each monitor output can be switched into either L or R, regardless of which side of a stereo send it occupies. Master Section (1) Master Section (2) WEDGE MONITOR SECTION In addition to the 20 output busses of the SM20 console, another four outputs are provided, which are designated wedge and alt wedge, in two stereo pairs. The wedge output normally outputs any PFL or AFL signals caused by an input or output solo being pressed, and when no solos are selected, the wedge output would normally be silent. However, the L/R TO WEDGE button allows you to listen to the L/R mix through the wedge output as the default monitoring state. An alternate wedge output is also provided, to allow you to monitor your outputs on another system, e. g. you could have the wedge output feeding conventional wedges and the alt wedge output feeding an in-ear system. The MONO SOURCE L & R buttons allow you to send the left or right monitor, or solo signals, to both sides of the wedge output if you're monitoring in mono. If both buttons are pressed, a mono sum of both sides of the signal is heard. The headphone volume control is also situated within the wedge monitor section. The headphone socket itself is recessed and positioned at an angle to the console's control surface, and is driven by a high-power (1W into 8) headphone amplifier. LAMP ILLUMINATION The LAMP DIMMER control affects the brightness of the LittliteTM connected to the adjacent XLR socket, and also of any connected to the back of the console. Another feature of the SM20 is the Clear-ComTM loopthrough connection on the console's back panel (two XLRs: one male and one female). When this is connected to an intercom loop, it will detect a call signal and the console lamps will flash, making it easy for your front-ofhouse engineer to attract your attention. PSU TALLIES Three LEDs offer constant visual confirmation that the 48V, ±17V and +5V rails on the console's power supply unit are running correctly. The SM20's power supply is the CPS800, which shares many design characteristics with the high-powered CPS2000, as used on the Series FIVE front-ofhouse and FIVE Monitor consoles. [. . . ] Phase reverse and insert switching work in an identical fashion to the output section. The TB OSC button allows the L and R busses to receive talkback, tone or pink noise from the oscillator and talkback sections on the right hand side of the master section.
