The Target
Set channel gains so signal peaks around -18 dBFS on the DM7 input meters during the loudest moments. This gives you enough level to work with, enough headroom for transients, and keeps faders and processing operating in their intended range.
- Too low: You compensate by pushing faders and the mix buss too hard — noise floor comes up with it
- Too high: You clip the preamp before the signal reaches the fader — no amount of pulling faders down fixes upstream distortion
How to Set It on the DM7
- Have the musician play at their loudest — hard hit on drums, belted note on vocals, full strum on guitar
- Adjust the Gain knob (analog preamp, top of channel strip) until peaks land around -18 dBFS on the input meter
- Set the channel fader to unity (0 dB)
- Repeat for every active channel
Starting Points by Source
| Source | Typical Gain Range |
|---|---|
| Kick drum (mic) | 40–55 dB |
| Snare (top mic) | 45–55 dB |
| Overhead / room | 35–50 dB |
| Electric guitar (DI or mic) | 30–45 dB |
| Bass (DI) | 25–40 dB |
| Acoustic guitar (DI) | 35–50 dB |
| Vocals (dynamic mic) | 50–65 dB |
| Vocals (condenser) | 40–55 dB |
| Keys (DI) | 25–40 dB |
These are ranges, not rules. Trust the meter over the number.
Examples
Scenario: Snare sounds thin and quiet in the mix. The instinct is to push the fader up. The correct move is to check the input meter first — if it's peaking at -30 dBFS, the gain is too low. Bring the gain up to -18 dBFS, then evaluate the fader position.
Scenario: Vocal channel sounds distorted even with the fader pulled down. Gain is set too hot — the preamp is clipping before the fader. Pull the gain knob down until the input meter peaks around -18 dBFS.
