Soundtracs - Topaz 12 4 Manual

Using the 24-8 manual, keep these differences in mind:

| Feature | 24-8 Manual says... | On your 12-4 | | :--- | :--- | :--- | | Channel count | 24 mono + 4 stereo returns | 12 mono + 4 stereo returns | | Master section | 8 group faders | 4 group faders (G1-4) | | Aux sends | 6 aux sends | Same (6 aux sends) | | Direct outs | Post-EQ, pre-fader | Same (on each channel) | | Tape returns | 24 channels | 12 channels (TR1-12) | Soundtracs Topaz 12 4 Manual

Soundtracs (later Soundtracs/QSG) went out of business years ago. The 12-4 was the baby of the Topaz series, and sadly, the specific manual for the 12-input, 4-bus version is extremely rare. Most of the "manuals" floating around are actually just the block diagram and spec sheet. Using the 24-8 manual, keep these differences in

Mic/Line → Gain Trim → HPF (80Hz) → Insert Send → EQ (3-band, fixed mid) → Insert Return → Aux Sends (1-4) → Pan → Channel Fader → Routing switches (Group 1-4 / L-R / Off)
