Bought the SQ-5 with two DX168 stageboxes for a dawless production rig with 8 stereo synths, guitar, mics, and outboard FX. After full configuration, here's the honest take.
What's great: Excellent 96 kHz audio quality. 32-channel USB multitrack to DAW is the killer feature — every channel captured individually with stereo mixdown alongside. The free DEEP Tube Stage Preamp adds real character, especially on thin sources like Volcas. Internal FX are competent (2× SMR reverb, delay, ADT) and integrate cleanly alongside hardware effects. SLink rock-solid — two DX168s on a single Cat5e cable, plug and go.
What to know before buying: The "Getting Started" guide assumes prior digital console knowledge. Realistic first-session config time: 4-6 hours. Several gotchas: FX engines used as channel inserts don't reset cleanly when unassigned. Scene Recall filters and Safes need genuine understanding to avoid overwriting your work. Insert toggle isn't assignable to a Soft Key (long-standing feature request). The Windows generic USB driver can't handle 32 channels at 96 kHz — install the proper A&H ASIO driver. The 48-channel engine includes 3 stereo + 1 USB slot, but they're convertible to mono in Input Stereo config (not obvious from the manual).
On the DX168: Quality remote I/O over one Ethernet cable, but each box adds 16 physical inputs that land on the existing channel pool — it doesn't proportionally double your usable capacity. Plan accordingly.
Verdict: Punches above its price tier on audio quality and recording integration, but unforgiving of casual setup. Once configured, it disappears into the workflow. Ideal for methodical builders doing hybrid hardware/DAW production. Less ideal if you want plug-and-play analog-mixer simplicity.
5 stars for capability, 4 for first-week experience, 5 once you're past the learning curve.
