The Sonic Imagery Labs, Model 898B is a high performance professional grade tool used to convert single-ended unbalanced -10 dBV consumer line level analog audio signals to balanced +4 dBm professional line levels - and vice versa. It is the only product available on the market that provides 8 channels in each direction, simultaneously. The 898B does not use transformers and it’s active circuitry is specifically designed to be uncolored and reproduce at it’s outputs, what is input, to a extremely high degree of accuracy.
Unbalanced input connections typically should be kept as short as possible to prevent the undesirable effects of microphonics, hum and noise pickup. The Model 898B allows the conversion to and from balanced lines that can be run up to 500 feet without audible loss of audio quality.
Signal to noise and common mode rejection performance are perfectly preserved by using the 898B. The 898B incorporates precision trimmed components that are fully specified for high performance analog audio frequency applications. It has outstanding AC characteristics, including ultra low harmonic distortion (0.0006% at 1KHz), and the ability to drive capacitive lines and remain stable, high slew rate (15V/uS) and DC to 200Khz bandwidth.
The Sonic Imagery Labs Model 898B is designed and manufactured for use in applications in the areas of scientific research, data aquisition, broadcast audio, recording studios and playback/transport audio systems. It's features include the following:
• 8 Channels of -10dBV to +4dBm Conversion
• Nominal input reference level -10 dbV(0.316Vrms)
+4 dBu to -10 dBV (XLR3 Input to RCA Type Output)
• Nominal input reference level +4 dBu (1.228Vrms)
• Unit Size
