Studio Electronics BOOMSTAR 5089 Classic Analog Moog DB24 Ladder Clone Module

 

SPECIFICATIONS & FUNCTIONS

 

Construction

 

Sturdy steel chassis, 31 pots, 2 rotary switches, 18 toggle switches––15 three way for expanded functionality, through hole circuit boards, AC power adaptor.

 

Dimensions

 

Height: 2.05" (52.07 mm) at front, 3.625" (92.075 mm) at back, Width: 8.7 " (220.98 mm), Depth: 7.05" (179.07 mm).

 

Sound Generation

 

All discrete circuity. Hand matched transistors in filter and amplifier.

 

Oscillator 1

 

6 position rotary range switch; Two center off toggle switches select combinations of sine, triangle, saw and square waveforms; Pulse width for square waveform; Sub oscillator with center off toggle switch for half and full level positions; Sync oscillator 2 to oscillator 1 switch.

 

Oscillator 2

 

6 position rotary range switch; Three position toggle switch to select triangle, saw or square waveform; Fine tune pot; Mod depth pot with center off toggle switch to select modulation by envelope 1 or 2; Keyboard tracking on-off switch.

 

Filter / Envelope 1

 

Frequency and resonance pots; Center off toggle switch to select half and full keyboard tracking; Envelope mod depth pot; Additional mod depth pot with center off toggle to select modulation by oscillator 2 or the LFO. Envelope 1: Attack, decay, sustain, and release pots; Center off toggle switch to select envelope invert or envelope loop.

 

Filter Types

 

4075-classic Arp 2600, 5089-classic Moog® 24db ladder, SEM-classic Oberheim® 12db (full function, with LP to HP mix control), 303-classic Roland® TB.

 

Envelope 2

 

Attack, decay, sustain, and release pots; Center off toggle switch to select envelope invert or LFO gate trigger; Single or multiple triggering switch; Center off toggle switch to select drone and envelope 1 as master. With master selected, envelope 2 is the modulator for both the amplifier and filter frequency. Envelope 1 remains active for oscillator 2 frequency and oscillator 1 pulse width modulation.

 

XMod

 

Oscillator 2 mod depth pot with center off toggle switch to select modulation of oscillator 1 pulse width or oscillator 1 frequency.

 

LFO

 

Rate pot; Midi sync on-off switch; Waveform pot––sine, triangle, saw up, saw down, square, offset square 1 and 2, random and slew random waveforms; Mod depth pot with center off toggle switch to select oscillator 1 frequency or oscillator 1 pulse width; Mod depth pot with center off toggle switch to select oscillator 2 frequency or oscillator 2 pulse width.

 

Amplifier

 

Center off toggle switch to select two levels of overdrive; Volume pot.

 

Additional

 

Master tune pot; Bend range pot; Glide time pot: Dynamics to filter frequency pot; Envelope 1 to oscillator 1 pulse width pot.

 

Mixer

 

Oscillator 1 level pot; Oscillator 2 level pot; Ring Modulator level pot; Noise level pot; Feedback pot.

 

Front Panel Jacks

 

CV in, Gate in; Filter frequency modulation in; Amplifier modulation in; Oscillator out; External signal in.

 

Back Panel Jacks

 

Midi In, Midi Out, 1/4" Audio out, DC power input.

 

Back Panel Switches

 

Learn switch: Select midi channel, note priority, aftertouch and mod wheel assignment; Tap tempo for LFO.

 

Overflow Switch

 

For polyphonic "Boom-Starring."
