Thank you for choosing Senal.

The Senal ASM-6 Two-Way Active Speaker is designed for near-field monitoring in professional audio applications. The ASM-6 features active filter technology and a dual-channel power amplifier, driven by a 6.5" 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-6 to handle high sound pressure levels in a compact 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. There is also a three-position high-pass filter for low-frequency cutoff that makes it easy to match the speaker with a subwoofer. The ASM-6 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 speaker can also be mounted on a wall or a stand via the mounting threads on the cabinet.

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 3.5" (9 cm) or more from the wall to prevent early reflections, which can interfere with stereo imaging.

For stereo placement, space the speakers equally to form an equilateral triangle with the listener at the third point of the triangle.

For five-channel placement, arrange the speakers in a circle, with the listener in the center. As with stereo placement, the left and right speakers should form an equilateral triangle with the listener. Place the center speaker between the left and right speakers, so they are spaced evenly at 30^ from each other. Place the rear left and rear right speakers behind the listener, at an angle of 100^ to 120^ from the center speaker.

Note that both setups are perfectly symmetrical, with each speaker at an equal distance from the listener, and the right and left sides a mirror image from each other. For optimal audio performance, the listener and the center speaker 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

Before connecting your speaker to the audio source and the power source, make sure that the speaker and the audio source are turned off and that the volume controls are turned all the way down.

1. Determine whether the line level output of your audio source requires an XLR or an RCA connector. If your audio source requires an XLR connector, use the included XLR to XLR cable. If your audio source requires an RCA connector, use the included XLR to RCA cable.

1. Use the included AC power cable to plug the speaker into an AC power source.
2. Turn on your audio source and the speaker.
3. Use the volume controls on the speaker 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 speaker 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.

You can adjust the high-pass (HP) filter to cut off low frequencies at 38, 48, and 58 Hz. This feature is ideal when matching the speaker with a subwoofer. When using the speaker in pairs, we recommend setting the HP switch to 38 Hz.

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 recommended that you do not adjust this setting.
