    The SM16 is a 16 bus dedicated monitor console to complement the Vienna and Europa FOH desks. The key features of the SM16 are: • 16 mono sends • stereo send • individual ON and PRE/POST fade switching on all sends •...
  • Page 7 Metering Each input module has its own bargraph meter in the overbridge. The groups are metered by bargraphs which are next to the faders on the output modules. The stereo mix/solo metering is by two illuminated VU meters, with integral peak LEDs, in the overbridge above the master module.

  • Page 8: Precautions And Safety Instructions

    General Precautions Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions where it is likely to be subject to vibration, dust or moisture. Do not use any liquids to clean the fascia of the unit: a soft dry brush is ideal. Use only water or ethyl alcohol to clean the trim and scribble strips.

  • Page 9: Signal Levels

    Signal Levels It is important to supply the correct input levels to the console, otherwise signalto noise ratio or distortion performance may be degraded; and in extreme cases, damage to the internal circuitry may result. Likewise, on all balanced inputs avoid sources with large commonmode DC, AC or RF voltages, as these will reduce the available signal range on the inputs.

    The SM16 is designed for reliability and high performance, and is built to the highest standards. Whilst great care has been taken to ensure that installations are made as troublefree as possible, care taken at this stage, followed by correct setting up will be rewarded by a long life and reliable operation.

    Input The sensitivity of both the XLR and the HIGH IMPEDANCE (HI-Z jack) inputs is adjusted by the SENS control. Both inputs are electronically balanced. XLR input sensitivity: -2dBu to -70dBu, +10dBu to -20dBu (switched range.) High Impedance input sensitivity: +10dBu to -20dBu When the RNGE (Range) switch is depressed the lower sensitivity range of the input is selected to allow line level signals to be used.
  • Page 21 The HMF’s Q is 1.3, and is increased to 2.6 by depressing the HI-Q button. The peaking LMF (Low Mid) section has a maximum cut or boost of 15dB and the frequency is variable between 150Hz and 3kHz. The LMF’s Q is 1.3, and is increased to 2.6 by depressing the HI-Q button. The shelving LF section has a maximum cut or boost of 15dB and the frequency is variable between 20Hz and 400Hz.
  • Page 22 Insert Point The module insert point uses a groundcompensated send and an electronically balanced return, at a nominal level of -2dBu. The signal is accessible via separate 1/4" jacks on the rear connector panel. The insert point may be set to pre- or post-EQ by pushon jumpers. The factory default is post-EQ.

    Stereo Mix The post-fader signal is sent to the stereo mix bus via the L/R (level) and PAN controls. The PAN control gives a 4.5dB centre drop. The mix bus send is activated by the ON switch, which has an integral green LED, and may be set pre- or post-fade by the PRE switch.

    Eight output modules are fitted in each console. The output module contains two group output sections, stacked one above the other. The lower sections control groups 1 - 8, while the upper sections control groups 9 - 16. The two sections have identical facilities.
  • Page 29 Talkback The momentary TB switch feeds the signal from the TALKBACK MICROPHONE to the group output; it is independent of the Fader position and the CUT switch. The group output is dimmed by 6db, and the engineer’s wedge speaker is dimmed by 20dB while the TB switch is active. Talkback may also be routed to all the group buses simultaneously by the INT talkback function on the master module;...

    RS5512 LAMP OSCILLATOR The master module contains the stereo mix or sidefill output, the operator’s LEVEL headphones and wedge speaker outputs, a noise or sine wave test oscillator, the solo mode controls and master solo clear function, and internal/external talkback FREQ functions.
  • Page 35 Output Phase The PHASE switch, which has an integral red LED, reverses the phase of both left and right outputs. The outputs themselves are electronically balanced at +4dBu, on male XLRs on the rearcon. External Input A stereo external input, from XLRs on the lower rearcon, may be added to the mix buses.
  • Page 36 RS5512 LAMP External Solo Signals OSCILLATOR The PFL, AFL Left and AFL Right external inputs, from XLRs on the lower rearcon, allow signals from another console to be added to the PFL and AFL buses. The LEVEL external PFL level is trimmed by the PFL TRIM pot. When no solos are active on the console, both PFL and AFL left and right external signals are monitored by the FREQ ’phones and wedge.
  • Page 37 -20dBu and -50dBu. The momentary action FOH button, which has an integral green LED, initiates talkback to the front of house console using a Soundcraft proprietary system. The talkback mic signal is switched to the FOH OUT XLR, with a +15v DC common-mode voltage to signal the FOH console (a Vienna, Europa or 8000) that talkback is occurring.

    Mute Masters The four, latching, Mute Master buttons M1 - 4, which each have an integral red LED, control the four mute buses. Any inputs assigned to a mute bus will be cut by the appropriate mute master. PSU Status Indicators The three PSU Status Indicator LEDs (red) show that the PSU rails +/-17v (both sets of rails), +24v and +48v are working.

  • Page 42 SPECIFICATION NOTES AND CONDITIONS A The Console has a nominal output level of +4dBu: all input sensitivities are relative to this, i.e., with line input gain set to ’0’, an input of 0dBu will give an output of +4dBu at any group or mix output, and a sensitivity of +4dBu gives unity gain from input to output.
