Classic 1050 sequential mixer module from the '70s Authentic reproduction of the circuitry from the "2500" Series Features sequential switching for rapid selection of waveforms and signals in a conventional audio mixer format Dual 4-input mixers with electronically gated inputs and eight-step counter and clock Each of the 8 audio inputs has its own attenuator and each dual output has a master gain control Can be used as an 8-input mixer with 2 adjustable outputs or as 2 separate 4-input mixers Illuminated push buttons select and indicate which inputs are gated Exclusive-On push buttons turn on a specific channel while turning off all others to preview signals Clock pulse generator can be switched on/off to sequence the channels in numerical order at a rate set by the Pulse Rate control A rotary switch controls the step length of the sequence and can set the clock to off Module can be clocked externally or connected internally and controlled by the 1027 or connected to a 1026 module to generate preset voltages Eurorack specs: 24HP, 110 mA +12 V, 20 mA -12 V SPECIFICATION Inputs Inputs 1 – 8 Type 8 x 3.5 mm TS jacks,  DC coupled  Impedance 50 kΩ, unbalanced Max input level +20 dBu External advance input Type 1 x 3.5 mm TS jack,  AC coupled  Impedance 10 kΩ, unbalanced  Max input level +10 V  External gate link input Type 1 x 12-way 0.1"  box header, DC coupled  Impedance 10 kΩ, unbalanced Max input level +5 V  OutputsOut A / B Type 2 x 3.5 mm TS jacks,  DC coupled  Impedance 1 kΩ, unbalanced  Max output level +20 dBu  Controls Channel level knobs 8 x rotary knobs  Channel on / off buttons 8 x buttons, LED backlit  Exclusive-on buttons 8 x momentary switches Level A / B 2 x rotary knobs External gate 1 x 2-position switch Enable / disable, switchable Controls Pulse gen / Manual advance 1 x 3-position switch  Pulse generator on / off / manual advance, switchable   Counter / mixer 1 x 3-position switch  Left position, 4/2 counter with 4/2 mixer  Center position, 4/2 counter with 8/1 mixer Right position, 8/1 counter with 8/1 mixer"  Pulse rate 1 x rotary knob,  0.5 Hz to 150 Hz   Counter 1 x 9-way rotary switch  Off / 2 / 3 / 4 / 5 / 6 /  7 / 8, selectable" Power Power supply Eurorack Current draw 110 mA (+12 V),  20 mA (-12 V)  Physical Standard operating temperature range 5° C to 40° C  (41° F to 104° F)  Dimensions 122 x 129 x 42 mm  (4.8 x 5.1 x 1.7") Rack units 24 HP Weight 0.30 kg (0.66 lbs)
