Series TWO Input ChannelsMONO INPUT CHANNELBenefiting from 27 years of Soundcraftconsole design experience, the Series TWO’sinnovative circuit design allows for theinclusion of more features than ever beforeat such a low cost. From the all-new micpreamp design at the top to the flattenedfader-tray at the bottom, the Series TWO’sfeature-packed mono input channel ensuresoptimum sound quality and controlthroughout the mix.

INPUT SIGNAL METERINGEvery input channel on the Series TWO has itsown, dedicated 12-segment LED bargraphmeter which reads the peak level of the pre-fade, post-EQ input channel signal. Theuppermost LED on the meter, identified by theadjacent legending ‘PK’, has a peak holdfacility which monitors both the insert sendand pre-fade signals, warning the engineer inthe event of clipping in either signal path.

INPUT STAGEThe -20dB gain change switch combines withthe SENS control to create an input stagewhich allows signals from -60dBu up to amaximum of +26dBu to be accommodated,and by splitting the control into two ranges,allows finer adjustment. The high maximuminput level means that even the hottest micsignals from snare or kick drums can behandled via the XLR input. The -20 switchworks as an active gain change rather than apassive PAD, and provides better noise andcommon mode rejection performance as aresult. Also included at the input stage is aphase (ø) switch which inverts the phase ofthe signal.

FILTERINGA switchable high-pass filter can be set toremove any unwanted low-frequency contentin the range 40 to 400Hz.

EQUALISATIONThe Series TWO’s EQ section follows the classic4-band design pioneered by Soundcraft in the1970s. Two sweepable mid frequencies areprovided, the lower of which operates between80Hz and 1.9kHz, with the high-mid accessing550Hz to 13kHz. LF and HF are also provided.All four bands provide an impressive gainrange of ±15dB. The entire EQ section can beswitched in and out of circuit.

AUX SENDS8 Auxiliary sends are provided, switchable inpairs to be pre or post fade. When the PRE=PREQ switch is engaged then anyAuxiliaries which are set to pre-fade will alsobe sourced pre-EQ.

ROUTING & PANNINGThe channel output is routed to the 8 Groupoutputs in pairs, with the PAN controlsweeping between the odd and even-numbered busses. The MIX switch routes thesignal to the main Stereo output bus, while theMONO switch allows a separate Mono Mix tobe generated from a selection of channels, foruses such as a foyer mix or for driving acentral speaker cluster.

FADER & MUTINGThe Series TWO frame is designed to separatethe faders from the rest of the input channel,placing them in a flat area at the front of theconsole. This provides a clear, uncluttered areain which to mix.

The MUTE switch, accompanied by an LEDactivity indicator, cuts the output to all busses- Auxiliary and Group - regardless of pre orpost-fade settings. It can be operated locallyor controlled by a mute group or MIDIsnapshot from the master section. The mode ofthe SOLO switch, which again is accompaniedby an LED, is determined on the mastersection. It can either function as a mono PFLto the engineer’s headphones or monitors, orcan be configured to trigger a Solo-in-place(SIP) whereby all other channels are muted.

The DIR PRE switch causes the direct channeloutput to be sourced pre-fade and pre-mute -very useful for providing feeds for livemultitrack recording.

REAR PANEL CONNECTIONS+48V phantom power is available on all monoinputs, and is enabled via the rear panelswitch. The mic input is via a low impedancebalanced XLR, while line level signals caneither be connected via the XLR input, or tothe high impedance balanced 1/4" line jack.Plugging into the jack socket will override anysignal connected to the XLR. The line jack isisolated from phantom power. The channelinsert is on a 1/4" jack with the send on thering and the return on the tip. The directoutput is on an impedance balanced 1/4" jack.

STEREO INPUT CHANNELAll the Series TWO’s frame sizes incorporatetwo stereo input channels, which are locatedjust to the left of the master section and aredesignated as STE 1 and STE 2. Similar inoperation to the mono channel, they providethat crucial additional flexibility required forcomplex live setups.

INPUT SIGNAL METERINGJust as the mono inputs, all four stereo inputs(L and R for each of STE 1 and STE 2) featurededicated 12-segment LED bargraph inputsignal meters.

INPUT STAGEThe Series TWO’s stereo input channels aredesigned for line level signals, and input gain isadjustable by a single rotary pot.

EQUALISATIONFour bands of EQ are provided: HF, HMID, LMIDand LF. The entire EQ section can be switchedin and out of circuit via the EQ switch.

AUX SENDSThe eight discrete Auxiliary sends route asummed stereo signal to each of the monoAuxiliary sends. Each pair of sends isswitchable pre or post-fade.

ROUTING & BALANCEThe channel output is routed to the 8 Groupoutputs in pairs, with the BALANCE controlgoverning the stereo spread between the oddand even-numbered busses. The MIX switchroutes the signal to the main Stereo output bus.

FADER & MUTINGAs on the mono channel, the LED-indicatedMUTE switch cuts the output to all busses -Auxiliary and Group - regardless of pre orpost-fade settings. The mute function can alsobe activated from the master section, via amute group or MIDI snapshot. The SOLO switchcan function as a PFL or, when Solo-in-place isengaged on the master section, can cause allother channels to mute while the soloedchannel is heard ‘in situ’ along with anyassociated effects.

REAR PANEL CONNECTIONSInputs to the two stereo channels are via fourbalanced 1/4" jacks.

Series TWO Master SectionThe Series TWO master section is positionedin the centre of the console, just to the rightof the two stereo input channels. It providesfinal level controls for all console outputs,houses the four stereo returns, and containscontrols for the 11x2 output matrix.

STEREO RETURNSAs well as the two fully-featured stereo inputchannels which are described earlier, the SeriesTWO also offers, as standard, four stereoreturns which are ideal for introducing pre-recorded sources or FX returns to the mix. TheTILT control emphasises either the high or lowend of the sound spectrum or, if left at itscentre detent, has no effect. Routing isthoroughly comprehensive; all of the 8Auxiliary busses can be accessed from 4 sendpots (Aux 1/3, 2/4, 5/7, 6/8) which are shift-switched in pairs to toggle between the formerand latter of the designated busses. All theGroup outputs and the main Stereo Mixoutputs can be accessed via individual routingswitches, while the 60mm fader is accompaniedby LED-indicated MUTE and PFL switches.

AUX MASTERSA bank of eight rotary master faders controlsthe final output levels of the Auxiliary busses.An AFL switch for each bus allows the outputto be checked on the monitor and phonesoutputs.

OUTPUT MATRIXThe presence of the output matrix offersadditional flexibility in the live mixingsituation. It feeds two additional consoleoutputs which can be sourced from any of 11sources: the 8 Group outputs, either side ofthe Stereo Mix output, and the Mono bus. Thisfeature is ideal for creating feeds for flownspeaker systems or for other parts of the

venue where different mixes are required. Twobanks of 11 rotary faders govern the mix forthe matrix, while master output rotary fadersare provided with AFL facility.

GROUP & MAIN MIX MASTERSIn the flattened fader tray at the front of theconsole, high-quality 100mm faders areprovided for Group outputs 1-8 and,immediately to their right, for the main Mixand Mono masters, which are coloured yellowand black respectively. Each of the Groups canbe routed independently to either or both ofthe Mix and Mono busses, and each has a panpot to determine its position within the stereofield of the Mix bus. PFL is provided for eachoutput. Each also has an insert point on theconsole back panel.

METERINGHigh resolution bargraph meters are provided,in the centre portion of the meterbridge.These provide metering for the eight Groupoutputs, each side of the Stereo Mix bus, andthe Mono bus. The mono meter also switchesto display PFL when required to do so. Themain left and right bargraph meters can beset to read the monitor output instead, bypressing MONITOR TO L-R METERS.

MONITORINGThe monitoring source, selectable betweenthe Stereo Mix bus, the Mono output and anexternal replay source such as a CD player, isfed to the front panel headphone socket aswell as to the stereo monitor output on theconsole’s back panel. The replay source hasits own level control and can be routed tothe Stereo Mix bus if required. Any soloedsignal will automatically override theselected monitor source for as long as theSolo is engaged.

TALKBACK & OSCILLATORThe talkback signal from a front panel mic XLRor the 1kHz test oscillator can be routed toany combination of Aux busses 1-4,Mix+Mono, matrix 1 and matrix 2.

MUTE GROUPS & MIDI SCENE CONTROLEight mute groups are provided, which arecreated by enabling the individual channelmutes and simply pressing STORE togetherwith the required mute master buttons. 128MIDI snapshots can be set up in the same way- when one is recalled, a MIDI program

change message is transmitted - ideal forchanging external effects patches. For scene-based mixing, mute snapshots can be recalledsequentially using the NEXT switch. Individualchannels can be set to mute safe to preventaccidental muting of important channels.

REAR PANEL CONNECTIONSThe master rear panel houses all the audioinputs and outputs for the master section, aswell as the heavy duty connector for thepower supply. The connections are as per thetable below.
