The RL 906D is a compact two-way loudspeaker consequently optimised for usage as a near-field
monitor. Either in an outside broadcasting van, on top of the meter bridge or in the home studio
and even as an precious hi-fi monitor it is more than convincing.
The RL 906D is identical in construction to the RL 906, which comes with an additional AES3 digital
input. There is an input selector on the back, where the left channel, the right channel or the
mono sum could be selected. According to all our other products, there is also the possibility to
use an analogue input signal. To synchronize the digital audio signal, with the video signal, you
could delay it in 16 steps frame wise. The frame refresh rate could be programmed internal.
By Musikelectronic Geithain’s coaxial technology a directivity was realised, that is especially adjusted
to the requirements of near-field monitoring, meaning small base widths and short listening
distances. Homogeneity, neutral tone quality and directional definition are most widely compatible
to the greater speakers from the RL series. This allows seamless working without familiarisation
phases along the whole audio production, regardless if it is in an outside broadcasting van, the
cutting room or in the great studio. The RL 906D is barely greater than a controlling monitor, but
it houses the power capability of a full-valued studio monitor. The bass reproduction as well as the
maximum level meet the requirements of most challenges. In 5 channel applications, demanding
a higher level in the lowest frequency range, the RL 906D is perfectly combined with our models
from the Basis series whereby it moves closer to the greater models.
The loudspeaker is equipped with a 13 cm (5”) cone woofer and a coaxial arranged 25 mm (1”)
tweeter. Each is powered by a separate MOSFET-amplifier with active crossover and electronic
overload protection. The amplifier is situated in the back of the cabinet. The RL 906D provides
a balanced XLR-type input with an adjustable input level. To compensate their placement, the
speaker features three controllers to continuously adjust the high- and low-frequency response
and also the frequencies around 300 Hz. These
controllers are attached to the cabinet’s backside. A
two-coloured LED indicates the state of the amplifier
and warns of clipping.
A variety of special stands and racks is available as
accessories. According fixing elements have been
integrated into the loudspeaker cabinet.
