The RCF EVOX App ensures a comprehensive control of J Series mixers from your smartphone, via Bluetooth. The app allows you to navigate between pages and fully control the mixer’s parameters even while playing. DYNAMIC COMPRESSOR MIC/LINE inputs 1 to 4 are provided with a single control dynamic compressor. The control slider acts on the amount of compressor intervention. A dedicated button toggles the compressor ON and OFF. Up to 6 different presets can be selected from the Compressor Model list: LIGHT, HEAVY, VOCAL, BASS, ACOUSTIC, and DRUM. MAIN CHANNEL A 7-band graphic EQ on the Main Channel lets you shape the frequency response of the system. In order to have a powerful overall sound, limiting peaks and more harmonics, four mastering processing presets can be selected: MASTERING, MASTER BOOST, LOUD & PROUD, and HI-FI. TONS OF EFFECTS 80 High Quality effects presets from the premium Z.CORE.DSP, each with three parameter controls: 40 different reverbs, providing a realistic simulation of large spaces, such as halls, rooms or hardware reverbs; 20 different delay types; 20 modulation effects to shape any nuance of your music. MFX with AMP MODELING Line input 4 can be switched to a Hi-Z mode and offers a 3 stage multieffect, including a realistic amp modeling simulator. Guitar and Bass players can count on a whole range of 15 emulations tuned for maximum reality: Darkface ’65, Jazz C, Rock’64, Rock 800 Crunch, Rock 900 Lead, Top30, Modern, Bassamp, Bassmate, Markbass 1, Markbass 2, Slo 88 Crunch, Slo 88 Lead, Overange 120, Heavy 51 and others.

Verdict

The call

The clearest difference is review sentiment: K at 100% against Evox's 8%. K also leads on rating (5.0 vs 2.0) and update cadence (every 2 months vs every 9 months). Evox's advantage is ratings volume (14 vs 1) and iOS requirement (9.3 vs 13.4). On price, ads, in-app purchases and monetization model there is nothing between them.
