XTA Announces New DP548 Dynamic Audio Processor

“You can think of the DP548 as ‘a DP448 on steroids’, but that only paints part of the picture." - Bill Woods, XTA

On top of all this is powerful dynamic EQ. Three bands of SiDD’s dynamic EQ are available on each input, with all four modes of operation supported (so, cut/boost either above or below the threshold).

Each band covers the full 20-20k range and has controls for envelope (attack/release) as well as setting the maximum allowable amount of gain adjustment and choosing the “strength” of the effect (the ratio in dynamics terms).

Dynamic EQ may be stored in its own memories, as can graphic EQ settings, all other input settings or all output settings, and every combination of these if necessary.

It is all still editable via the front panel, and AudioCore opens up the dynamic EQ ediitng in a highly intuitive manner.

Routing inputs to outputs is very flexible, with any input or combination of inputs being switchable to any output. There are also various useful templates to get users started (along with default crossover points to help).

The DP548 also supports a full matrix mixing mode where inputs may be mixed in any ratio to any outputs with four “sends” being available on each output channel instead of just switching on/off.

Looking at output sections, the requisite crossover filters offer slopes from 6 dB/octave up to 48 dB/octave. Nine more bands of parametric EQ follow, and then there is a choice of dynamics useful for protection or for creative use.

Before the limiter sections there is now a fully featured compressor with variable knee to turn it from a safe corrective tool with hard knee to a gentler (but still with a high ratio if required) effect that only makes its presence felt gradually as the threshold is approached and exceeded.

Each output also features a combination of limiters – a limiter designed to protect individual drivers from over-heating, and an additional look-ahead “D-Max” limiter for added safety and to prevent driver over-excursion. Add to this sub-millimetre accuracy when introducing time alignment with completely flexible ganging of all channels.
