Undertone Audio
Summary
Abstract
Undertone Audio (UTA) is a boutique manufacturer founded by Eric Dela Cruz, known for versatile, high-quality preamps and channel strips. The MPDI-4 and the discontinued MPEQ-1 are community favorites. UTA gear is described as “incredibly versatile” and “made for the everyday recording engineer,” with a mic preamp that ranges from crystal clean to usable distortion and a DI flatter than an Avalon U5.
Key Characteristics
- MPDI-4: Four-channel mic preamp with built-in DI, praised as a major upgrade from interface preamps
- MPEQ-1 (discontinued): Combined mic preamp, DI, and parametric EQ described as criminally undervalued — “should be worth 5x what it’s selling for”
- The EQ on the MPEQ-1 is unique and difficult to grasp but does things “no other EQs do in the hardware world”
- DI section is flatter than an Avalon U5, making it excellent for clean DI capture
- Mic preamp can go from crystal clean to usable distortion
- Also makes a Varicap cable system for guitar DI recording
Use Cases
- Vocal tracking — versatile enough to handle any genre
- Clean DI capture for bass and guitar reamping
- MPEQ-1 used across mix bus with gentle Pultec-style boosts
- Swiss army knife EQ for problem-solving difficult sources
- Replacement for interface preamps as a significant step up
Settings & Sweet Spots
- MPEQ-1 on mix bus with gentle low and high shelf boosts — “incredibly musical”
- The MPEQ-1 manual includes recipes for replicating Pultec, API 550, and other classic EQ curves
- Clean DI with Varicap cable for guitar captures intended for reamping
Comparable Alternatives
| Gear | Notes |
|---|---|
| Chandler Limited TG Channel | Different flavor; some prefer Chandler for vocals, UTA for flexibility |
| Neve 1073 / BAE Audio | More colored; UTA offers broader tonal range |
| Focusrite ISA / Audient ASP880 | Budget alternatives that UTA significantly upgrades from |
| Fearn VT-1 | Different color; tube-based alternative |
Common Mistakes
- Dismissing the MPEQ-1 EQ as too complex without investing time to learn it
- Not realizing the MPEQ-1 is discontinued and increasing in value on the used market
- Expecting 500-series headroom from UTA gear — the full-size units have significantly more headroom
- Overlooking the DI section, which is one of the flattest available

“If it’s in the cards financially, it’s a tool that really should be worth 5x what it’s selling for. The mic-pre is amazing and can go from crystal clean to usable distortion, the DI is flatter than an Avalon U5, and the EQ is just on its own planet.” — cian riordan

“I loved the undertone solo’d but the chandler worked better for me. On the other hand oaklandmatt and cian riordan get fantastic results with the undertone.” — BatMeckley
