The dbx 150 series provides professional quality noise reduction for the small recording studio, semi-professional recordist, and serious audiophile. The 150 series is compatible with dbx professional studio systems. Tape recordings encoded on dbx 150 series may be decoded on dbx professional models and vice-versa. This compatibility allows recordings made on the 150 series to be re-mixed or mastered at studios using professional dbx noise reduction systems. The 150 series has models available with two modes of operation for the noise reduction process.

Simultaneous code-decode: Each channel has separate code and decode noise reduction electronics which allows monitoring of the decoded signal during recording.

Switchable code-decode: Models with this feature have only one noise reduction circuit for each channel. They must e switched to record (encode) and must remain in that mode continuously during the recording process. When playback is desired, the noise reduction electronics must be switched to the playback (decode) mode. 

Three models are available in this series:

Model 157 - two channels of simultaneous code and decode

Model 152 - two channels of switchable code or decode

Model 154 - four channels of switchable code or decode

Any pair of the 150 series can be rack mounted utilizing the RM-150 rack mounting kit (occupies 3 1/2" of panel space).

Features included 10 dB additional headroom, in excess of 30 dB noise reduction, over 100 dB dynamic range, low distortion for complete code-decode cycle, excellent transient tracking, no pilot tones or complex alignment procedure, and low cost.

Sound on sound, ping-pong, or duplication through several generations will not color the sound. Clarity of sound, perfect transient reproduction, and total absence of audible background noise can be achieved only with dbx noise reduction.
