    Replaced my stetsom 2448 with this to get more overall control of each individual speaker and the sound is amazing. You wont regret this purchase. Just take your time tweaking it to get the sound to what your looking for, it is a process.

    I think this is best dsp out there for the price..I wish the you tube videos would go more in depth with the functions on how to tune it in... all the videos I watched, each one of them, the person doing the review says they will do another in depth video but none of them have yet..

Through an LCD display and intuitive interface, it allows real-time audio adjustments. The DSP 2.8X features 2 audio inputs (A and B) and 8 independent outputs and allows you to choose the audio source (A, B or A + B) for each output. It has an integrated equalization system, with 15-band graphic equalizer, manual tuning, or through 12 presets (Flat, Loudness, Bass Boost, Mid Bass, Treble Boost, Powerful, Electronic, Rock, Hip Hop, Pop, Vocal and Pancadão).

For professional equalization adjustments, it has 1 INPUT Parametric Equalizer and 1 OUTPUT Parametric Equalizer with gain control, specific frequency setting, and equalizer bandwidth, allowing fine adjustments and detailed equalization control. The Crossover function allows you to precisely define the cut frequencies, attenuation rates, and topology of the LowPass and HighPass filters with Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB / 8ª).

To aid in the protection of amplifiers and loudspeakers, the DSP 2.8X features a Limiter with Dynamic Attack-Release system that dynamically controls the Attack and Release parameters in real-time, providing security and sound fidelity.

In the audio treatment, it also has Alignment capabilities through High Accuracy Delay, Phase Inversion, Independent Gain by Output and Master Level. For accurate measurements and adjustments, the DSP 2.8X features an integrated Audio Generator with tone generation and frequency sweep, and Pink Noise. Configuration Copy functions between output channels. It also has the functions of Management, Save and Load Settings in memory, Security Password that blocks the editing of the parameters, Marquee / Text Display, and Language Selection.

Sequencer Feature

Allows sequential triggering of other products through the remote trigger connection (REM). Use a cable of at least 20 AWG. The sequencer has three outputs (S1, S2, and S3) which are sequentially activated and deactivated according to the input signal from the remote input (REM IN).

The triggering interval between each output can be set from 0s to 4s. When the set time is 0s, all three outputs will be enabled and disabled at the same time after 3s of the input remote (REM IN) signal change.
