What is an ADSP Filter Kit?

The ADSP Filter Kit consists of a 3⁷/₈" L x 2³/₈" W x 2⁵/₈" H BHI ANEM MKII noise suppressing filter, 2.5 watt amplifier, and interconnecting cables.

What does the ADSP Filter Kit do?

The ADSP Filter Kit removes noise and static from the audio signals as they travel from the Icom M802 radio to the Icom M802 speaker. The ADSP FilterKit provides three important benefits:

Improves your ability to hear weak signals. It does this by electronically removing atmospheric white noise, hiss, and static, and passing the voice signal, effectively "popping" the desired signal up above the background noise.
Helps to eliminate "listener fatigue" caused by the constant din of atmospheric noise, hiss, and static.
Provides filtered audio to your headphones. You can listen to the same clear sound through your headphones/ear buds that you hear through your Icom speaker.

What the ADSP Filter Kit doesn't do.

While the ADSP Speaker Kit eliminates atmospheric white noise, hiss, and static, and significantly improves your ability to hear the weak signals, it cannot correct problems caused by a poorly designed, maintained, or improperly installed SSB system. The ADSP Speaker Kit eliminates noise from the audio coming out of the SSB radio. It does not prevent the SSB from receiving interference radiated by other onboard equipment (RFI), nor RF noise entering the radio through the antenna or power leads (not usually a problem with Icom Radios). This means that if you have a refrigerator, battery charger, ac inverter, etc., that shows as 2, 3, or 4 bars of noise on the radio's LCD display, you'll still have to turn that equipment off in order to receive weak (1-bar or less) incoming signals.

How does the ADSP Filter Kit connect to an Icom M802?

The ADSP Filter Kit uses the Icom Speaker supplied with the radio, maintaining the Icom-designed aesthetics of your radio installation.

Unplug the Icom SP-24 M802 speaker from the main unit of the M802.
Plug the 3.5 mm speaker extension cable into the speaker jack on the back of the Icom M802 main unit.
Plug the other end of the 3.5mm speaker extension cable into the "Audio jack on the ADSP module.
Plug the Icom SP-24 3.5mm plug into the "Audio Out" jack on the ADSP module.
Connect the fused 12 power cord to the vessels 12-24 vdc power.
Turn the Icom M802 and ADSP module on.
Select the level of DSP filtering you want (see ADSP manual for instructions).

What is an ADSP Speaker Kit?

The ADSP Speaker Kit is a BHI NES 10-2MKIII noise suppressing speaker system consisting of a DSP (Digital Signal Processing) chip-set and a 2.5-watt audio amplifier, packaged in a compact 4.3"L x 2.6"H x 2.2"D aluminum speaker case, a 1/4" to 3.5mm (1/8") phono jack adaptor to fit the Icom M700Pro/M710, and a fused power cable for connecting the speaker to your vessels 13.8 vdc power.

What does the ADSP Speaker Kit do?

The ADSP Speaker Kit takes the place of the M700Pro and M710's built-in speaker. The ADSP Speaker Kit provides three important benefits:

Improves your ability to hear weak signals. It does this by electronically removing atmospheric white noise, hiss, and static, and passing the voice signal, effectively "popping" the desired signal up above the background noise.
Helps to eliminate "listener fatigue" caused by the constant din of atmospheric noise, hiss, and static.

How does the ADSP Speaker Kit connect to an Icom M700Pro or M710 SSB?:

Three simple steps to connect:

Plug the 1/4" to 3.5 mm phono adaptor into the headphone jack on the back of the Icom M700Pro/M710.
Plug the DSP speaker lead into the phono adaptor.
Connect the fused 12 power cord to the vessels 12-24 vdc power.
Power-ON the M710/M700Pro and ADSP module
Select the level of DSP filtering you want (see ADSP manual for instructions).
