The NTS-4 is a small performance mixer from Korg's Nu:tekt line, made to sit at the centre of a hardware setup. Six channels, an effects loop and a bank of onboard processing handle a table full of grooveboxes and synths. Assembly comes first, since it arrives as a kit.
Inputs for a table of boxes
Four stereo channels and two mono ones take in six sources. Everything on that side uses 3.5 mm sockets, which is what most desktop gear puts out. Main outputs are quarter-inch, and a headphone jack covers monitoring.
Effects on the send and the master
Seven options live on the send and return loop: delay, ping pong delay, chorus, and four reverbs covering hall and slap types. Ten more sit across the master bus, from filters and an isolator through flanger, phaser and decimator to drive, distortion, compression and limiting. Between the two, a whole mix can be dubbed out from the front panel.
Sync and power
MIDI leaves on a 3.5 mm TRS jack, so clock and notes reach the rest of the rig. The unit runs on bus power through its Type-C port. Idle draw is 0.1 W. A 9 volt adapter is offered separately, and it is worth checking whether your setup needs one before you order.
Build and size
You put it together yourself, with a USB Type-C to Type-A cable and printed instructions in the box. Finished, it measures 195 by 125 by 38 mm and weighs 613 g. A three-digit display shows what you are adjusting.
