BSS AR133 Aktiv DI-boks

Active Direct Box AR-133 . Signals from electronic instru- ments such as guitars, keyboards and similar sound sources gener- ally have a low level, high im- pedance output, which will not interface with the low impedance balanced input found on professional sound mixing con- soles. Furthermore these signals cannot be driven up long cable lengths without serious loss of level and degradation. The DI box converts this signal to a more suitable form without interfering with or modifying the signal at the instrument source, and should provide freedom from ground and power line related problems. Passive DI boxes have limited applications as they will inevita- bly affect the signal source for guitar type applications, and can also have an insertion loss of around 20dB. The only safe and predictable way to provide direct feeds from instruments or other sources is by using an Active DI box utilising an input amplifier driving an output transformer. The AR-133 fulfills all the requirements of an active DI and more.
