Information

This new AKG reverberation system has been improved in many design aspects but continues on the veil proven and superior design elements of our well known BX 20, Special care has been taken in expanding the sound qualities and at the same time reducing size and weight of our previous system. Our patented Torsional Transmission Line (TTL-System) has been improved by extending the overall length of the system by about 25 % in relation to the BX 20 system and at the some time reducing the overall size dramatically to about one-third. Besides conventional shelving type frequency controls for the reverberated output signal, we incorporated o high-cut filter at the input/reverb drive Amplifier. This feature will provide the selection between a bright, more aggressive sound or an alternatively mellower, more natural sound in reverberation. Both types of reverberation will be required, depending on the program material. The reverb section has been separated from the electronics and from channel to channel for easy serviceability. Plugin p.c. boards are used for the electronic circuitry within the control module. This module may be removed from the main housing and operated by an optional extension cable up to 10 m (30 ft) away from the reverb section . The decay time of both channels may be adjusted independently on the remote control unit, which is included in the delivery . Features- o Genuine two-channel design. Either channel can be used and control led separate I y . o Smaller and substantially improved design to well-known BX 20, o Improved low sensitivity to structure born vibrations . o Patented circuitry to avoid any direct (dry' signal at the reverb output. o Frequency response may be altered both, at input and output of reverb section . o Built-in limiter for reverb drive signal with LED indication on front panel . o Input and output level adjustable on the connector panel. o Remote control of reverb time. o Switchable to mono drive of both channels. o No locking or re-adjusting when used in OB-vans or on the road. o Built-in protection for shipping, which may be easily removed upon receipt of unit.
