TWO WAY POWERED
STAGE MONITORS

The Road 15A is a 2-way powered stage monitor
that incorporates a 15R4 cone loudspeaker for
bass reproduction. High frequencies are
handled by an M-75 compression driver with

1.5” exit, a 3” titanium diaphragm and EFW
voice coil. The 60° x 40° rotatable horn allows
for high frequency coverage options when the
situation calls for it.

The biamplified system uses a 3G Class “D”
amplifier. With a 24-bit DSP providing FIR (Finite
Impulse Response) filters, unparalleled control
over critical signal parameters can be
accomplished.

The monitor’s low profile design, side
mounted handles, and strategically located
skid plates allow for ease of use onstage.
Hidden connector plugs and indicator LEDs
offer an undistractive reference for the artist
and a clean stage appearance.

Housed in the birch plywood enclosure
finished with durable Iso-Flex black paint and
sturdy speaker grilles for “performer’s abuse”,
the Road-15A is available in Left or Right hand
versions.

Frequency Response

Shows the frequency response
of one unit, radiating to a half
space environment, at the
position of the ear and driven
by a -20dBu swept sine wave
signal.

Black: Monitor EQ.
Red: Main EQ.

Distortion

Shows the Second Harmonic
Distorsion (grey) and Third
Harmonic Distorsion (dotted)
curves for a unit driven by a
swept sine wave signal
(-10 dBu input).

Horizontal Directivity of two
units, HF drivers outside
(Recommended).

Shows normalized horizontal
isobar plot for two units,
with the Low Frequency drivers
next to each other.
1/12th octave resolution.

Horizontal Directivity of two
units, HF drivers inside.

Shows normalized horizontal
isobar plot for two units,
with the High Frequency drivers
next to each other.

Measurements setup.

All measurements have been made
to reflect real-life usage conditions,
with the monitor on the floor and the
microphone placed on the HF axis
at the position where the ear of an
average height person would be.
Isobar directivity plots were obtained
in a closed space to resemble a
practical application.

NOTES: Frequency response measured outdoors at a distance of 1.95m (6.5ft) from the front grille.
For identification of potential feedback frequencies, only light smoothing (1/12th octave) has been used.

Product improvement through research and development is a
continuous process at D.A.S. Audio. All specifications subject
to change without notice.
