POWERHOUSE digital audio processor
Preliminary information on a current
design project at Weiss Engineering Ltd.
Overview ! 4 slots for audio I/O interface cards. on the back of the Powerhouse unit. How does the Powerhouse
The Powerhouse is a "black box" type universal Formats like AES/EBU, analog, Firewire The first interface available will be an 8 compare with the Weiss
digital signal processor for audio. Software is etc. are supported channel in / 8 channel out AES/EBU card.
! CF card on frontpanel for standalone Others to follow include analog and Gambit Series Equalizer and
downloaded via Ethernet from a host
computer. Control of the Powerhouse is also applications firewire. Dynamics units?
done via the host computer. The host ! extensive sync source selection (internal /
computer typically is a PC or Mac, but can also external / audio I/O) The Gambit Series Equalizer and
Synchronisation Dynamics units (EQ1 and DS1) are two
