DirectOut has announced v6.4 firmware update for its Andiamo series of audio converters, adds the ability to sum input signals onto four summing buses such that communication signals maybe be gathered from a larger number of devices (remote/mobile cameras) and be distributed as a bundle throughout a production site.

The summing can be configured with the routing matrix of the Andiamo Remote control software. All inputs that are routed onto a bus are summed to the same signal level. To avoid clipping, each bus has an individual master level that can be reduced in 6dB steps. The bus output may be routed to any physical output on the unit.

Demanding measurement tasks can also be performed by using the unit’s summing feature. Correlated input signals that are split across several analogue inputs may be summed to increase the signal-to-noise ratio (SNR) without compromising signal resolution when the bus master level is reduced. Using a simple splitter, the same signal can be routed to eight analogue inputs, for example. While the correlated part of the signal sums up by 18dB in this case, the uncorrelated noise of the inputs sums up by only 9dB, effectively increasing the already good SNR of the Andiamos to a -127dB (A weighted).

The latest version of Andiamo Remote and the new firmware can be downloaded from the DirectOut website. The new firmware is available for Andiamo 2 and Andiamo 2.XT (SRC), including the legacy hardware Andiamo and Andiamo.XT (SRC) units.
