About the D8B UFX Card
The Mackie UFX card provides robust processing power for computation-heavy plug-ins. The UFX card is a 4-in/4-out architecture, which means it can support four mono, two mono and one stereo, or two stereo sends simultaneously. Up to four UFX cards can be installed in the D8B, allowing up to sixteen simultaneous single-channel effects, eight stereo plug-ins, or combinations thereof.
Note: It is recommended that you increase the D8B’s memory if you install more than one UFX card. Memory upgrade instructions are supplied with each card.
About the RTA-31
Acuma Labs' RTA-31 is a dedicated software plug-in for the Mackie Digital 8•Bus that utilizes 24-bit digital processing power to view and modify the frequency response from any given signal within the D8B. An invaluable tool for live sound and studio applications, the RTA-31 lets you create great sounding mixes quickly and easily. View frequency response using the onboard spectrum analyzer to quickly identify the peaks and valleys of your signal. Modify frequency response using the To EQ function, which automatically compensates for the highs and lows of your signal. A unique feature called Sweep Draw lets you quickly paint any EQ curve using your mouse like an on-screen paint brush. Save your edits and settings as presets or create comparative editing references by toggling (morphing) between the Memory A and B settings. The Spectrum Analyzer has a selectable dB reference level (0dB to –60dB) that enables you to zoom in on a specific signal range. Five different graph types (bar, peak hold, peak difference, point, and peak bar) are available for various display options. As with all Mackie plug- ins, 31-Band Graphic EQ+ Analyzer can be routed via channel insert, auxiliary sends, or inserted on the main Left and Right Masters.
