SE Electronics DM3 Dynamite Active Direct Box
Thank you!
Thank you for choosing the sE Electronics DM3. We hope you enjoy using it as
much as we’ve enjoyed designing and building it for you.
The DM3 is an active DI, employing the well-established DYNAMITE technology of
our DM1 and DM2 inline preamps. Its Ultra Hi-Z input, massive headroom and
dedicated Class-A output-buffer amplifier ensure that you’ll 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. Its compact size allows it to easily fit into your pocket,
so the sound quality you’re looking for is always at your disposal.
Please note: The DM3 requires +48V Phantom power for operation.
Ultra Hi-Z input
The DM3’s ultra-high input impedance preserves the individual sonic character of your instrument without any compromise. Instruments with passive pickups (i.e. electric guitars, stringed instruments with piezo pickups, vintage high- impedance microphones) will especially benefit from the DM3’s stunningly high input impedance of 10 MOhms.
Attenuation pad
For high-output instruments (i.e. electric guitars with active pickups,
keyboards, drum machines) a three-position attenuation switch allows you to
reduce the signal by 15 or 30 dB. This is useful if the signal level is too
high for the input of your preamp or mixer.
Please note: The switch is embedded in a recess to prevent unintended access;
you will need a miniature screwdriver to change its settings.
Ground lift switch
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 our innovative new On+ circuitry. The
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. Please be aware that results depend
on the noise source; your individual setup and radio frequency environment
(i.e., cell phone proximity, wireless broadband services, power supplies, Wi-
Fi and Bluetooth devices, transformers). Not all humming or buzzing is
generated by group loops.
Please note: The switch is embedded in a recess to prevent unintended
access; you will need a miniature screwdriver to change its settings.
Lockable 1/4” input jack
The DM3’s 1/4” input jack has a locking mechanism that
prevents unintended disconnection. This is ideal for both studio and stage
applications.
Powering
To ensure proper operation, your sE product requires a Phantom power source that provides 48 Volts according to IEC 61938.
Risk of damage
Do not connect your sE product to any power supply other than a Phantom power
source (input with Phantom power or external IEC standard Phantom power
supply) with a floating connector, using a balanced cable with studio-grade
connectors to IEC 268-12 only. This is the only way to ensure safe and
reliable operation.
Please be aware that Phantom power cannot pass through TRS connectors. A
balanced microphone cable with XLR connectors at both sides is required to
provide Phantom power to a microphone.
