A Beast of A DI In-Line Active DI for Instruments Ultra-Hi-Z, Lockable 1/4″ Input XLR 3-Pin Output Class-A Output Buffer and Amplifier Switchable 15- or 30-dB Input Pad Three-Way Ground-Lift Switch Runs off 48V Phantom Power Durable, All-Metal Housing The DM3 Dynamite In-Line Active DI from sE Electronics is an impressively compact, active DI with an ultra-Hi-Z input and massive headroom for connecting electric guitars, bass guitars, piezo pickup instruments, keyboards, synths, drum machines, laptops, and even vintage microphones while preserving the individual sonic character of each to get the best out of your instruments. Leveraging the DYNAMITE technology found in the DM1 and DM2 in-line preamps, the DM3 sports a stunning 10 Megohms of input impedance, and the ultracompact form factor ensures you can take the DI anywhere, as long as there is 48V of phantom power, commonly provided by mixers, PAs, and audio interfaces. The DM3 comes with a switchable 15- or 30-dB input pad for high-output instruments, such as electric guitars and drum machines, and a handy three-position ground-lift switch, which can eliminate unwanted buzzing and humming in not only the low-frequencies, but also the high-frequencies as well. With a gold-plated XLR output, a locking 1/4″ input, which helps avoid accidental disconnects, and a durable all-metal housing, the DM3 is ready for the rigors of the road or the dynamic needs of the studio. Dynamite Sound in Your Pocket The DM3 employs the well-established DYNAMITE technology of the sE DM1 and DM2 in-line preamps in order to achieve high-quality sound in a pocket-sized form factor. Its ultra-Hi-Z input, massive headroom, and dedicated Class-A output buffer and amplifier ensure that you will always get the best out of your instrument. The DM3 can be directly connected to any phantom-powered XLR input, with no need for an extra cable. Active in-line DI Ultra-Hi-Z 1/4″ input with massive 10-megohm input impedance Locking 1/4″ input for avoiding accidental disconnects Gold-plated XLR 3-pin output Extremely high headroom with Class-A output buffer and amplifier Switchable 15- or 30-dB input pad for high-gain instruments Three-way ground-lift switch Runs off 48V phantom power New Ground-Lift Circuitry The DM3 features a dedicated three-position ground-lift switch. In the Off position, the ground lift is deactivated. If you are experiencing unwanted hum or buzz, a ground loop might be causing this. Turning the switch to the On position will break any such loops, greatly reducing noise. The switch’s third position engages the new On circuitry. This innovative electronic design can help to reduce unwanted noise, not only in the low-frequency, but also in the in the high-frequency range. This is a great option if you are still experiencing a hissing sound or radio-frequency interference with the ground lift engaged.
