Sonic Imagery Labs 898B 8 Channel Bal 8 Channel Unbal Line Level Shifter Interface

General Description:

Specifications, Datasheets and OpsManual available at: sonicimagerylabs.com


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).
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’s rugged steel one rack space package and performance provides the answer to the most demanding applications requiring precision level conversion and input - output line balancing and unbalancing.
