Model 898B - 8 Channel Balanced 8 Channel Unbalanced Line Level Translator "The Universal Translator" Updated July 2nd, 2013 Model 898B Datasheet and Specifications PDF Model 898B Operation Manual and Specifications PDF General Description: 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 an extreme high degree of accuracy. Today’s multichannel sound of 4, 5, 6, 7 or more channels makes using two channel interfaces cumbersome and expensive. Furthermore, the greatest need by far is to translate consumer level outputs to professional levels. It is perfectly suited to the vast majority of multichannel uses in the studio, broadcast center, live applications, and the theater. Mixing of consumer and professional grade audio equipment is occurring more and more. For example, consumer DVD players cost far less than pro versions, but don’t readily connect to the input of a studio console or monitor system. Another example: the high-end power amplifiers being used in home theaters have balanced line level inputs and can’t be driven directly from the consumer decoders and preamps. In such cases, a multichannel consumer-to-pro level interface is needed that can receive from a consumer level RCA jack at -10dBV (316mV RMS) and send to a pro level XLR jack at +4dBu (1.228V RMS). 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. Features: 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.
