Description
introduction
New TOPP PRO TDI -A2 direct injeciton box active is made for stage use and its rugged case ensures it will last for years
A Di box is an impedance matching and singnal balancing device for Guitars and other musical intruments
A Direct injection box converts high impedance unbalanced signals to low level balanced output signals for use with audio equipment such as mixing consoles etc
it also ensures propeer electrical signals are maintained throughout the signal chain and allows long
cable runs while cancelling interference and noise
FEATURES
converts high impedance unbalanced signals to low- level balanced signals
Rugged construcction
solid rubber feet
unbalanced input/output impedance 50k ohms
balanced i/o is low noise for long-distance and weak signal transmit
Ground botoom make the noise of input lower when transmitting
Attenuation 0dB 20dB
