INVENTORY #58409

BRAND: 4ms

MODEL: QPLFO Quad Pingable LFO

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for a 4ms QPLFO Quad Pingable LFO Eurorack Synthesizer Module. The 4ms Quad Pingable LFO (QPLFO) is a 12HP Eurorack module featuring four independent, clock-syncable LFOs with tap tempo and variable wave-skewing. It is widely used for creating rhythmic modulation and evolving textures in both small and large modular systems

SPECS:

• Four Independent Channels: Each channel functions as a separate LFO with its own frequency, wave shape, and reset capabilities.
• "Pingable" Frequency: The speed of each LFO is determined by the time between pulses ("pings") received either via the tap-tempo button or the external Ping jack.
• Wave Skewing: A dedicated Skew knob and CV jack allow for continuous transitions between waveshapes—from an exponential-like "pluck" at minimum, to ramp-down, triangle (at 50%), and ramp-up (at 100%)—without losing synchronization.
• Bipolar and Unipolar Outputs: Internal jumpers allow you to switch the output range between -5V to +5V (bipolar) and 0V to +10V (unipolar).
• One-Shot Mode: If the external ping clock is stopped, the Reset jack can trigger the LFO as a single-cycle envelope.
• Fire-on-Unmute: Optional jumpers per channel can be set so that unmuting an LFO automatically resets its cycle.
• Floating Reset: Holding a high gate on the Reset jack allows the LFO to run freely without re-syncing to the ping clock.
• Internal Patching: Rear headers allow for normalization to other 4ms modules, such as connecting to the 4ms Quad Clock Distributor (QCD) to automatically sync all four LFO channels to master clock outputs.
• Width: 12HP.
• Depth: 1.57” (40mm).
• Frequency Range: 0.0002Hz (approx. 71 minutes per cycle) to 500Hz, with marginal tracking up to 1kHz.
• Power Consumption:
  • +12V rail: 89mA max (with external 5V) or 154mA max (with internal 5V).
  • -12V rail: 73mA max.
  • +5V rail: 65mA max (if using external 5V source).
