The Complete Guide to the Soundtracs Topaz 12-4 Manual and Console
Channel strip controls and use
- Front-end: Each channel provides mic/line input with gain trim, a low-cut/filter (on many units), and an insert point for external processing. Expect +4/-10 switching on line inputs in some variants.
- EQ: Usually a 2- or 3-band semi-parametric EQ per channel (high/low shelving with mid sweep on many models). EQ bandwidth and center frequencies are conservative—designed for musical clarity rather than drastic shaping.
- Routing: Channels route to main L/R mix plus four subgroups (4 buses). Subgroups let you group drums, guitars, vocals, etc., for collective processing or level control. Aux sends are typically pre/post switchable for monitor mixes or effects sends.
- Monitoring: Control room/phones section provides talkback, cueing, and level metering. Metering is typically analog VU or LED ladders—useful for setting consistent levels.
- Inserts/Direct outs: Many Topaz consoles offer channel inserts and direct outs to multitrack recorders; check the manual for insert point wiring (tip/ring/sleeve stereo insert wiring on TRS jacks is common).
- Power and grounding: Internal linear PSU on many older Soundtracs boards—good for audio character but ensure proper grounding in studio environments to avoid hum.
