Mackie DL32SE – a 32-channel digital rack mixer with 32 Onyx+ preamps, 10 fully assignable XLR outputs, a 32×32 USB audio interface and wireless control via the Master Fader SE app (iOS, Android, macOS, Windows). 48 kHz / 24-bit, 1.5 ms latency, THD+N <0.005%.
The DL32SE is a stagebox/rack enclosure with an integrated carry handle and rubber corners – fits 4U of rack space or sits directly on stage while the engineer mixes from anywhere on the floor via a Wi-Fi router. Steel construction, internal power supply, no touchscreen or physical faders – all control and DSP is handled by the Master Fader SE app running on up to 20 devices simultaneously. The absence of a hardware control surface is a deliberate design decision that removes the fixed FOH position entirely.
Per-channel and per-output DSP – a complete system in a single box
Each of the 32 input channels carries a 4-band parametric EQ (Vintage and Modern modes), HPF, gate and compressor. Each of the 10 outputs adds a 31-band GEQ, LPF, alignment delay and RTA/Spectrograph. Routing is fully flexible: 8 stereo-linkable aux sends, 6 stereo-linkable subgroups, Main L/R bus, 6 VCAs and 6 mute groups. Four stereo FX processors with dedicated sends and returns cover reverbs, delays, choruses and flangers without occupying input channels or physical outputs.
Multitrack recording and virtual soundcheck
The 32×32 USB 2.0 interface records all input channels simultaneously to a DAW during the show, then plays them back the following day as a virtual soundcheck – without musicians present. A dedicated stereo return channel accepts intermission music or backing tracks directly from a DAW or playback device. EIN sits at –127 dBu (A-weighted), analog dynamic range exceeds 110 dB (A-weighted) and SNR at +4 dBu is above 92 dB unweighted – figures that hold up against purpose-built studio hardware.
