Millenium DI-33 Active DI Box User Manual
Introduction
Using a DI box eliminates the need for miking of the backline speakers, providing a clean feed to both console and amplification. The D1-33 has a parallel feed from the input connector so that the instrument may be simultaneously connected to the D1-33 and the amplifier. This means that no special splitter cables are needed.
The striking visual design of the D1-33 also has functional qualities. For example, cables can be run underneath to keep cable runs neat on stage, and all from one end of the unit. The molded sides make stacking of multiple units easier, and help isolate the case of the D1-33 from the stage both electrically and mechanically.

the system.
Functions and Facilites
The Link Connector
The 1/4” LINK socket carries a parallelwired direct feed from the input.
The On/Off Switch
The On/Off switch is used for both phantom power and battery. To avoid battery
drain when the unit is not in use, ensure that this switch is set to the upper
OFF position when storing or packing the D1-33.
Phantom Power
The D1-33 can work reliably on a wide range of phantom power voltages,
although of course the typical supply provided by modern consoles is +48
volts. The D1-33 accepts supply voltages of +48 volts down to +20 volts
without loss in performance.
While the Dl-33 is receiving good phantom power, the power LED is lit continuously. Should the supply fail for any reason, the Dl-33 will switch over automatically to run from the internal battery (as long as one is fitted!). Under these conditions, the power LED flashes approximately every 2 seconds. Installing a battery To install or replace the internal battery, first undo the knurled screw on the battery compart-ment – DO NOT undo the flush panel screws. The battery cover should now fold back towards the edge of the unit, revealing the compartment. Attach the flying lead battery terminals to your battery, and slide the battery into the compartment, with the connector towards the outside of the Dl-33. For best reliability and long life, we recommend you use only high quality alkaline batteries in your Dl-33.
Cable Management
To keep cables tidy on stage and in the studio, both input and output cables
can be arranged to run in the same direction by bringing one cable back under
the Dl-33 .
Environmental Protection
For the transport and protective packaging, environmentally DC friendly materials have been chosen that can be supplied to normal ‘1:J recycling. Ensure that plastic bags, packaging, etc. are properly disposed of. Do not just dispose of these materials with your normal household waste, but make sure that they are collected for recycling. Please follow the notes and markings on the packaging.
