OSCILLATOR DEVICES Siren Quick Start

• Input A/B: Two 1/4" mono jacks. Check chapter Input Sensitivity for high input levels like active pickups.
• Output A/B: Two 1/4" mono jacks for outputs.
• Power: 9VDC only, Center Negative, Boss Style power supply. Min. 150mA.
• MIDI In: 3.5mm (1/8") MIDI Input according to MIDI Standard MIDI TRS Type-A.
• MIDI Thru: 3.5mm (1/8") , latency free MIDI Thru
according to MIDI Standard MIDI TRS Type-A
• Phase: With the Phase function, the phase
of Channel A is flipped.
• Split: The Split function connects Channel A
with Channel B BEFORE the volume control.
• Mix: The Mix function blends Channel A
with Channel B AFTER the volume control.
The blended signal is provided on Out A and Out B.
To select the Split and Mix settings press and hold the PHASE button until it starts flashing. By repeatedly pressing
the PHASE button, you can scroll through any combination of Split and Mix shown by the orange light of the LEDs.
Press and hold the PHASE button to save the selection.
Upon delivery the SIREN is set to +6dB pre-gain. With that the knobs at noon is unity gain. When running hot signals
into the SIREN, for example active pickups or already boosted levels, said pre-gain can be set to 0dB to avoid
clipping. Unscrew the backplate and set the DIP switch between the sockets to either On (0dB) or Off (+6dB) for
each channel seperately.
MIDI commands override the knob settings (except the MIDI command for relative volume). When turned, the
knobs override MIDI commands.
