Thank you for choosing Senal.
The ASM-3 Two-Way Active Speakers are a pair of powered
stereo speakers designed for near-field monitoring in
professional audio applications. Their convenient size
makes them equally ideal for desktop audio systems. The
ASM-3 features active filter technology and a dual-channel
power amplifier, driven by a 3″ woofer and 0.8″ metal dome
tweeter that deliver a wide and flat frequency response with
pristine audio reproduction and accurate sound imaging. The
cabinet’s curved port tube provides natural low-frequency
output and minimizes distortion, while the ellipsoidal
design and rigid, high-intensity aluminum alloy construction
prevent diffraction and cabinet resonance. This meticulous
engineering allows the ASM-3 to handle high sound pressure
levels in an ultracompact cabinet size.
Fine-tune settings allow the user to adjust the high, mid, and
low frequencies to compensate for the listening environment,
speaker placement, and audio source. Each ASM-3 comes
with a rubber base that isolates the speaker from its resting
surface to prevent resonant coupling, and makes it easy to
adjust the vertical angle of the speaker to down fire or up fire.
The speakers can also be mounted on a wall or a stand via the
mounting threads on the cabinet.

Precautions

Setting Up
Mounting the Speaker
For desktop placement,
place the speaker on the
included rubber base. This
base serves to isolate the
speaker from its resting
surface and prevent
resonant coupling. The base
is designed to make it easy
for you to adjust the vertical
angle of the speaker to
down fire or up fire, so you
can aim the acoustic axis at
the listener’s ear.
The speaker may also be mounted on a wall via the mounting
threads on the rear of the cabinet, or on a speaker stand via
the threaded mount on the bottom of the cabinet. To mount
the speaker on a wall, you can use the Senal speaker bracket
kit, sold separately.

Speaker Placement and Positioning
Position the speakers 2.3′ to 6′ (0.7
to 1.8 m) from where the listener will
be situated, and aim the tweeter
at the approximate height of the
listener’s ears. There should be no
obstructions between the speakers
and the listener. Each speaker
should be 7.9″ (20 cm) or more from
the wall to prevent early reflections,
which can interfere with stereo
imaging.
For stereo placement, space the two speakers equally to form
an equilateral triangle with the listener at the third point of
the triangle.
For optimal audio performance, the listener should be on the
centerline of the room.

The Listening Environment
A room with dimensions that are multiples of each other,
such as a room that is twice as wide as it is tall, may result
in standing waves that can blur the bass frequencies. Large
areas of a smooth material like glass will cause acoustic
reflections and may interfere with sound-field reproduction
and imaging. You can avoid reflections by strategically
placing sound-absorbing materials like acoustic foam,
carpeting, and heavy curtains around the room.
Connecting the Speaker
1. Plug the stereo 3.5 mm connector of the included audio
cable into the audio output of your audio source.
2. Plug the left and right RCA connectors into the audio
inputs of the left and right speakers.
3. Use the included AC power cables to plug the speakers
into an AC power source.
4. Turn on your audio source and the speakers.

5. Use the volume controls on the speakers and your audio
source to adjust the audio level. When using an audio
source that has its own master level, such as a recording
console, turn the volume on the speakers all the way up,
and control the volume through the master level on the
console.
Fine-Tune Settings
You can fine-tune the frequency response of the speaker via
four fine-tune settings on the rear of the cabinet.
You can adjust the high frequency (HF) by ±1 dB and the low
frequency (LF) by ±2 dB. We recommend adjusting these to
suit the listening environment.
You can adjust the mid frequency (MF) by
-2 and -4 dB. We recommend adjusting
these to suit your speaker placement.
When the speaker is placed on a stand or
mounted on a wall, we recommend setting
the MF switch to 0. When the speaker is
placed on a desk or table and its face is
3.1″ to 9.8″ (8 to 25 cm) from the edge of
the desk, we recommend setting the MF
switch to -2. When the speaker is more than
9.8″ (25 cm) from the edge of the desk,
we recommend setting the MF switch to
-4. These measurements are approximate
and will depend on your specific listening
environment.

The frequency adjust terminal is for testing and adjusting the
curve. It had been adjusted in an anechoic chamber to its
optimal position, and we strongly recommend that you do
not adjust this setting.
