Connections¶

Power¶

The PolyPulse power input is 5V DC center positive. The actual power consumption is around 600-800mA but a stronger power supply of at least 2A is recommended.

While the PolyPulse can also be powered with a USB-A to barrel jack cable, it is not recommended to connect the PolyPulse to a computer or USB hub as it might result in audible hum/noise.

Disconnect headphones before turning on the PolyPulse, otherwise a pop is sent through the headphones (even if the volume knob is set to 0).

Warning

Connecting a power supply with an wrong voltage or wrong polarity WILL damage the PolyPulse. Please only use the supplied cable and power supply.

Turning off the PolyPulse¶

To safely shutdown the PolyPulse press edit+settings, select shutdown PolyPulse with X and press yes. Wait 10 seconds after the screen goes black before disconnecting the power cable. If the PolyPulse is not safely shutdown recently saved projects or samples might be corrupted.

Audio¶

The PolyPulse has balanced in- and outputs which allows for long cable runs with excellent rejection of noise and interference.

In live audio settings there is no need to use DI boxes for the outputs. As the PolyPulse outputs are already balanced they can be directly connected to the mixer or amplifier with TRS cables or a TRS → XLR cables.

Tip

Always connect the PolyPulse using TRS / balanced cables even when it is connected to a device with unbalanced inputs. When TS / unbalanced cables are used a hum/noise might be audible on the outputs.

MIDI¶

By mistake the arrows above the MIDI connectors are labeled the wrong way around on the first batch of PolyPulses. This is fixed starting with PolyPulse #00051. For older PolyPulses a sticker is supplied which can be placed on the back of the PolyPulse:

Trigger/gate¶

The PolyPulse has 5 trigger outputs and 2 trigger inputs. When power is applied to the PolyPulse the first trigger output (and corresponding LED) turns on for about a second.

Ethernet¶

The ethernet connector is used for uploading samples, downloading projects and Open Sound Control.
