We are unable to provide individual customer support with kit building so please see the detailed assembly guide at Rakit to gauge difficulty before purchasing. Once started, kits cannot be refunded.
Level: Channels 1-4
Each channel has a level control which ranges from off (fully anti-clockwise) to +10dB gain (fully clockwise).
Mute: Channels 1-4
Each channel has a mute switch which can be
useful to keep a level setting but still mute the sound on an individual channel.
Master Level
The master level control is used to adjust the level of channels 1-4 but does not affect the auxiliary input.
The Rakimix can be daisy chained with other Rakimixers to create a larger channel count mixer.
This input can be used with any mono audio signal up to approx 4Vpp, the signal will be buffered and mixed with channels 1-4.
Any level adjustment of the auxiliary input signal should be done on the source device.
4 x Mono, perfect!
2 x Stereo, great!
Channel 1 > Tip/Left
Channel 2 > Ring/Right
Channel 3 > Tip/Left
Channel 4 > Ring/Right
1 x Stereo, 2 x Mono, outstanding!
Channel 1 > Tip/Left
Channel 2 > Ring/Right
The mixer output signal is a mix of the 5 input channels transmitted to the tip and ring of a stereo output. A mono or stereo cable can be used on the output.
When using a stereo jack both left and right signals will be identical.
