SA263 Collider Delay+Reverb Owner’s Manual
Frequently Asked Questions
What kind of instruments can I connect to the Collider’s inputs?
The Collider’s audio inputs are high impedance (~ 1 MΩ) and they can accept high impedance signal
sources like guitars/basses with passive pickups, as well as low impedance sources like line-level
audio circuits, guitars/basses with active pickups, electronic keyboards, or mixer outputs. The input
circuit can handle signals ranging up to 6.0 Volts, peak-to-peak.
Can I power the Collider directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the Collider needs 9 Volts, so the Collider cannot be powered directly
from USB. Make sure that you have plugged in the included 9V DC power supply when connecting to
the Collider’s USB port.
When connecting the Collider to a recording interface or mixer, should I used a Lo-Z
(microphone) or Hi-Z (line / instrument) input?
The Collider’s output will be low impedance when the effect is active or in buffered bypass mode, but
it will be high impedance when using true bypass mode and a guitar with passive pickups. Therefore,
it is recommended that you use a high impedance (Hi-Z) input on your recording interface or mixer to
avoid signal loss.
Why doesn’t the Collider respond to MIDI messages being sent to it?
By default, the Collider should respond to MIDI continuous controller messages on channel 1. The
Collider’s MIDI channel can be configured using the Neuro Editors. Channel numbers in MIDI use
zero-based counting, so MIDI channel 1 is described as 0 in hexadecimal, MIDI channel 2 is described
as 1 in hexadecimal, and so on, concluding with MIDI channel 16, which is described as F in
hexadecimal. A continuous controller message starts with a hexadecimal B and is followed by the
channel number (0 through F).
So, the command byte from your MIDI controller should be formatted as shown in the following
table:
Each continuous controller command byte is followed by two bytes, the CC number and the value.
So, each CC message consists of a total of three bytes. If the Collider is not responding to MIDI, make
sure that your MIDI controller is properly configured and sending messages in the format described
above.
Can I use the Collider in my amp’s effects loop?
The Collider’s audio inputs can handle up to 8.76 dBu or 6.0 Volts peak-to-peak, which allows it to
work in most amp effects loops. Be sure to check your amp’s documentation to verify that the
maximum send level is less than the Collider’s maximum input level.
