In the 70s, the first 2500 series synth modules hit the market. They were super expensive back then, mostly featuring discrete transistor designs with some op - amps as op - amps were costly at that time. This discrete circuitry gave these modules a unique sound, and they were used by big - name artists like The Who, Jean Michel Jarre, Vangelis, and Kraftwerk to create some of the greatest records and film soundtracks. Modular synths were a huge milestone in electronic music, and now, it's getting even better.
Features:
- A classic 1027 clocked sequential controller module from the 70s.
- An authentic reproduction of the '2500' Series circuitry.
- Comes with an integrated circuit 8 - step counter and 3 control voltage channels (A, B, and C).
- 8 rows of 3 controls offer 3 independently adjustable voltage outputs for each counter step.
- A built - in time base generator enables the sequencer to step automatically.
- Each row has an adjacent LED indicator to show the sequencer count.
- An illuminated push - button starts and stops the internal clock.
- Adjust the internal clock rate from 20 steps per minute to 400 per second using the Pulse Repetition Frequency control and external rate control signal.
- Turn the internal clock on and off by applying pulses on the right input connections.
- Adjust the clock pulse width and step voltage duration from 0 to 100% with the Pulse Width control and external width control signal.
- Manually step and reset the sequencer using the front - panel push buttons when the clock is off.
- Control voltages on channels A, B, and C range from 0 to 10 V.
- Use the 1027 to control other 2500 Series modules like the 1026 Preset Voltages or 1050 Mix Sequencer modules.
- Rear PCB cable connections are provided (cable included).
- Eurorack specs: 26 HP, 50 mA +12 V, 30 mA - 12 V.
Using this Behringer 1027 sequencer is quite straightforward. First, connect it to other 2500 Series modules if you want to control them using the provided cables on the rear of the PCB. The built - in time base generator allows the sequencer to step automatically. You can start or stop the internal clock with the illuminated push - button on the front panel. To adjust the rate of the internal clock, use the Pulse Repetition Frequency control and the external rate control signal. This lets you change the stepping rate from 20 per minute to 400 per second.
The Pulse Width control and the external width control signal are used to adjust the clock pulse width and the duration of the step voltages from 0 to 100%. When you turn off the clock, you can manually step and reset the sequencer using the front - panel push buttons.
For maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If you notice any issues, check the cable connections first. The control voltages on channels A, B, and C range between 0 to 10 V, so make sure not to exceed this range to prevent damage to the module. Also, follow the Eurorack power requirements of 26 HP, 50 mA +12 V, and 30 mA - 12 V for proper operation.
