Joranalogue DIM 2 Dual BNC Lamp Dimmer User Manual
INTRODUCTION
For whoever has ever struggled with finding their way around a Eurorack synthesizer on a dark stage or a dimly lit studio, Dim 2 presents an illuminating experience. In just 4 HP, it provides a complete solution to upgrade your modular system with a pair of dimmable console lights. The high- efficiency PWM dimmers run at high frequencies, ensuring flicker-free and noise-free operation. Additionally, extensive line filtering keeps your Eurorack power supply happy and clean. Not limited to just manual control, both dimmers also feature control voltage (CV) inputs, turning the connected lamps from simple light sources to voltage-controlled audio-visual spectacles. While the use of the included BNC LED lamps is recommended in order to keep power consumption low, halogen lamps may be used as well. Provided your power supply is beefy enough, up to 6 W of power may be drawn from each output. This even makes it possible to drive 12 V LED strips, truly making your patches shine bright.
CONTENTS
In the Dim 2 box, you’ll find:
- Product card, stating serial number and production batch.
- 16-to-10-pin Eurorack power cable.
- Mounting hardware: two black M3 x 6 mm hex screws, two black nylon washers, and a hex key.
- Two BNC LED gooseneck lamps, in a protective cotton bag.
- The Dim 2 module itself, is in a protective cotton bag.
If any of these items are missing, please contact your dealer or [email protected].
CONTROLS & CONNECTIONS
BNC LAMP OUTPUTS
The two BNC outputs each provide up to 6 W of power, PWM-dimmable between 0 V
and +12 V. To connect a lamp, first line its connector up with the notches on
the socket, then rotate it clockwise by 90º until the BNC connector locks in
place. To release a lamp, push the BNC connector towards the front panel and
then rotate it anticlockwise by 90º. Use of the included LED lamps is
recommended. However, it is possible to connect any standard BNC lamp,
including halogen types. Note that some aftermarket LED BNC lamps are not
dimmable, although they can be used normally when the dimmer knob is set to
100 %. BNC adapters can be used to connect led strips and other 12 V lamps. In
this case, keep in mind that all current will be drawn from the system’s +12 V
rail, which should have sufficient power reserve available.
DIMMER KNOBS AND LEDS
Each BNC output has an associated dimmer knob, which will adjust the lamp’s
brightness from 0 to 100 %. The current status of each dimmer is displayed on
the adjacent LED. When using any of the CV inputs, the corresponding knob
becomes an attenuator for the incoming CV signal.
DIMMER CV INPUTS
These input sockets are used to provide direct voltage control over the
brightness of the lamps, with a range of 0 V to +5 V when the corresponding
knob is set to its maximum setting. When the B input socket is not used, it
will receive its CV from input A.
CAUTION: rapidly flashing lights may trigger seizures in people with photosensitive epilepsy.
