Thanks for purchasing the Nady SW-21 AB/Y
Switcher Signal Routing Box. The SW-21 is
a useful compact signal routing box. A/B-Y
switching works two ways: (1) it enables routing
a common source signal (guitar, bass or key-
board) between two amplifiers or amp channels
or to both amps simultaneously, and (2) it allows
selecting between two source signals (e.g., two
different guitars) into the same amplifier or to
use both sources simultaneously. Two LEDs
indicate whether A, B or Y routing has been
selected. The Y routing combines both the A and B outputs in parallel so, for example, two amplifiers
can be driven at once or combines two source signals so that two guitars can be used simultaneously .
The SW-21 provides full A/B-Y switching functionality, plus two Parallel in/out jacks.
Connecting source signals and amp inputs in parallel can affect audio levels and might require readjust-
ing your volume controls.
FEATURES
• Switches a signal between two different targets (e.g., amp A or B)
• Directs a signal to two targets simultaneously.
• Switches between one of two different source signals sent to one target
• Barely audible low switching noise
• Combines two source signals in parallel switched between two different targets
• Combines two source signals in parallel directed to two targets simultaneously.
• No bleed-through between channels
• LEDs indicate all signal routing selected
• Unplugging from jacks labeled “PARALLEL” turns off 9V battery
CONNECTIONS & OPERATIONS
(1) 9VDC Battery Compartment — Battery only functions to power LED indicators and unit can oper-
