Soundcraft EPM6 Helimikser

Soundcraft EPM6 — A 6+2 Analog Console with Pro-Grade Mic Preamps

The Soundcraft EPM6 packs the GB30 microphone preamp into a 6+2 analog console suited for live venues, houses of worship, rehearsal rooms, and project studios. Surface-mount construction preserves repeatable gain settings, while balanced XLR connections and integrated 48 V phantom power cover routing for small-format setups. Two configurable auxiliary buses give the desk room to run monitors and effects from a single chassis. Engineers wanting console-grade mic stages without a full-format footprint will find the right tool here.

GB30 Preamps and Proportional Peak Monitoring

The console ships with Soundcraft's GB30 preamp, designed by Graham Blyth for the company's 30th anniversary and shared with the larger LX7ii and GB Series consoles. Every mono channel carries a TRS insert for patching external processors. A multi-point Peak LED listens along the channel strip and brightens proportionally as clipping approaches — monitoring the entire signal path rather than only the output stage, so engineers react before distortion reaches the main bus.

Microphone Preamps Built for Real Headroom

GB30 preamps deliver high-resolution adjustment across a 55 dB gain range, with global 48 V phantom power feeding every mono input. Hot condenser and dynamic sources stay clean because the chain carries +22 dBu of headroom from preamp to output, letting percussion peaks and loud vocalists pass through without the preamp giving up.

• Microphone Preamp: Soundcraft GB30 — shared design with the LX7ii and GB Series consoles
• Gain Range: 55 dB — covers quiet acoustic sources to hot stage levels
• Engaging a global 48 V phantom switch feeds every mono input at once, removing per-channel toggles from the soundcheck workflow.

3-Band Channel EQ with Parametric Mids

Each mono input carries a 3-band EQ with a swept midrange, the band where vocal presence and snare articulation live. The mid sweeps continuously from 150 Hz to 3.5 kHz with ±15 dB of cut or boost, while shelving filters at 12 kHz and 60 Hz handle the band edges with the same swing. Stereo channels receive a simpler 2-band EQ for source playback.

• Microphone Channel EQ: 3 bands, parametric mids — swept midrange for targeted correction
• Mid Sweep Range: 150 Hz to 3.5 kHz — covers vocal warmth and instrument fundamentals
• On stereo inputs the swept mid is dropped in favour of fixed 2-band shelving, so playback material lands in the mix without extra knob turns.

Aux Buses, Inserts, and Honest Metering

Two configurable auxiliary buses switch pre- or post-fader so one console handles stage monitors and effects simultaneously. TRS inserts on every mono channel and on the main mix patch external processors without rerouting signal flow. Ten-segment LED output meters paired with per-channel proportional Peak LEDs show real-time headroom across the entire signal chain.

• Auxiliary Buses: 2 configurable — pre/post-fader per channel for monitor and effects duties
• Insert Points: TRS on all mono inputs and main mix — patches gear mid-chain without repatching
• Per-channel Peak LEDs glow brighter as clipping approaches, letting operators track shrinking headroom across the full signal path before distortion reaches the main mix.

Built for First-Time Engineers, Small Venues, and Branching Setups

This desk suits engineers upgrading from a basic interface who need real mic headroom on vocal and instrument sources. Solo performers running two to three gain stages benefit from auxiliary sends that don't burn channels on returns. Houses of worship, community theatres, and small music venues value the lack of onboard effects — fewer controls mean fewer mistakes during services and shows. The EPM6 ships as a desktop console requiring optional rack ears for 19" installation, fitting the operator who wants flagship mic stages on a side table or in a shallow rack shelf.

Soundcraft and the GB30 Heritage

Soundcraft has engineered professional mixing consoles for over four decades. Founder Graham Blyth designed the GB30 preamp for the company's 30th anniversary, originally deploying it in the LX7ii and GB Series before bringing it into the compact EPM lineup. The EPM family launched as a low-cost, high-performance trio in 6+2, 8+2, and 12+2 frame sizes built around repeatable analogue settings and surface-mount construction.
