Inside the DM3

  • DM3_14-aspect-ratio-545-390

    Ultra-HiZ input for getting the best out of your instrument

    With virtually no load on your instruments, the DM3 has a stunningly high 10 megaohms of input impedance, preserving the individual sound character of your instruments. Thanks to our well-established DYNAMITE technology used in the DM1 and DM2, the DM3 ensures maximum signal quality even on low-output pickups without coloration!

  • DM3_11-aspect-ratio-545-390

    Massive headroom for even the hottest instruments

    Built to handle even the highest output levels of the hottest active pickups, any keyboard, drum machine, synthesizer or laptop, to name a few sources. The DM3 can easily handle the roaring output of a 10,000-watt solid-state power amplifier (285 Vrms or 805 Vp-p)! If the signal is too hot, lower the input signal by 15 or 30 dB with the integrated, recessed attenuation pad switch to accommodate any input load.

  • DM3_15-aspect-ratio-545-390

    A new standard to the ground lift switch

    The DM3’s recessed three-stage ground lift switch features a unique “on+” setting, efficiently reducing not only unwanted buzz and hum but also hiss and undesirable radio frequency interference noise. Dial in the perfect setting for the cleanest signal, whether you are in the studio, recording at home, on stage at a concert venue, or in a worship setting.

  • DM3_23-aspect-ratio-545-390

    Lockable ¼” input jack and custom sE plug keychain

    The DM3 comes complete with a custom sE ¼” plug keychain and is equipped with a lockable ¼ inch (6.3 mm) input jack, so great sound is always by your side! The lockable input jack provides a secure connection in the most demanding, fast-paced live or recording environments where snags can happen. In addition, the locking mechanism can be disengaged if preferred.

  • DM3_22-aspect-ratio-545-390

    Dedicated Class-A output buffer amplifier and premium finish

    State-of-the-art electronics provide the lowest noise in its class, and proven Class-A design prevents zero-crossover distortion from being added to the signal. The DM3 ruthlessly buffers the signal independent from load impedance or cable length so that you can always count on a powerfully clean and consistent signal with a sleek finish that will last for years and years to come.

  • DM3_12-aspect-ratio-545-390

    Slim, all-metal discrete housing and gold XLR connectors

    The DM3’s all-metal design, high-quality manufacturing standards, robust construction, and gold-plated XLR connector provide a roadworthy design and reliable loss-free signal in an exceptionally compact form factor. The DM3 connects directly to interfaces, mixers, stage boxes, or any standard XLR input with no extra cable needed. All while being compact enough to fit in a pocket or hang from the included sE ¼” plug keychain, so great sound is always by your side.

What are the system requirements?

– output: preamp/mixer/audio interface providing 48V phantom power

What kind of instrument does the DM3 work with?

The DM3 is intended for use with any 1/4″ instrument cable – i.e. instruments or playback devices that use a 1/4″ unbalanced cable for the audio output, like a keyboard, drum machine, electric / bass guitar to name a few.

My DM3 isn't doing anything / I don't hear any signal / all I hear is a buzz or hum.

Please ensure the DM3 is connected securely between your microphone and your mic preamp, and make sure that +48V phantom power is turned ON on your mic preamp / interface / mixer.
