bhi DTNA Loudspeaker

bhi DTNA

The "Desktop Noise Away" (DTNA) loudspeaker greatly improves the intelligibility of any voice communications, by it amateur radio on shortwave or mobile radio (PMR, police etc.) on VHF/UHF. The large speaker is intended for stationary use with practically all radios, what's required is just a loudspeaker jack on the radio and a power supply. Equipped with a 4" base driver and a 1" tweeter, in conjunction with the ingenous noise reduction technology, the DTNA offers stress free listening over long periods of time.

Up to 8 levels of noise reduction are selectable with a button on the front panel. Another buttons turns the loudspeaker on and selects a few basic parameters. The integrated 2.5W RMS amplifier offers a good volume level even in noisy environments.

Included in the shipment is a 1.2m long connecting cable to the speaker jack of the readio, equipped with a 3.5mm phone plug, plus a power supply cable with fuses. The power requirements of the DTNA speaker is 12 to 18 VDC at max. 300mA. With the equally included mounting bracket the loudspeaker can be mounted to the wall, when used on the desk the bracket can be removed.

bhi DSPKR Loudspeaker

bhi DSPKR

Low profile DSP loudspeaker with large diameter (c. 10cm) for rich audio. The proven DSP technology by 'bhi' does the trick: with the push of a button you select one of 7 levels of noise reduction. This gives you the perfect adaption for every situation. Very easy to operate and ideally suited for amateur radio, in a taxi, for police or fire brigades, anywhere where wireless is used. And of course especially useful in a vehicle...
Built in is a powerful 10W RMS amplifier, which greatly helps in a car or another noisy environment. The large volume control sits conveniently on top of the case, just besides the other controls (push button, LEDs). At the side a 3.5mm phone socket offer connection for an additional loudspeaker or for headphones.
A sleepmode helps to conserve power, an evermore important feature wether in the car or at home. With a single touch of the push button the DSPKR comes back to work... Protection circuits against overcurrent and wrong polarity assure an easy installation.
Please note that this loadspeaker was designed for optimal voice audio reproduction, and is nit very well suitable for music.

bhi DSP loudspeaker and modules

Loudspeaker NES-10-2 Mk3 with built-in DSP filter. These loudspeakers are suited for HF and VHF use to reduce static, background noise etc. The comprehensibility is greatly enhanced, fatigue when listening for extended periods is avoided.

The model NES-10-2 allows for a variation of the DSP filter level in 8 steps (DIP switches on the rear of cabinet). Additionally the model NES-10-2 offers a volume control, On/Off switch for the DSP function and a 3.5mm mini jack for connection of a headphone or an additional external speaker.

Both models come with a 2m AF cable with 3.5mm mini plug (mono) and must be supplied with 12 to 28V DC, a DC cable is supplied. The supplied mounting bracket is helpful for installation in a car or at home.

NEIM-1031 Noise reduction module

Take advantage of latest DSP technology also without the loudspeakers, with the NEIM-1031 DSP noise elimination module. Utilizing the same DSP technology as the above shown loudspeakers but has several connections for audio in- and output. With these connections the NEIM-1031 can be easily integrated into any existiing audio system.

• Inputs: Line-In and loudspeaker input
• Outputs: Line-Out, loudspeaker and headphone
• DSP with 8 different levels of noise reduction
• Volume control
• Power requirements 12 to 24V DC, 500mA

NEIM-1031 with horizontal labelling

To use the NEIM-1031 in a horizontal position, we offer a sticker with horizontal labelling (instead of vertical).

NEDSP-1061 AF DSP Noise elimination module

Stamp size PCB (30x38mm) for internal use in most radios. Uses the same DSP technology as the well known loudspeakers. The module is simply installed in the AF line. Potentiometers for input and output lines are provided for required adjustments to different rigs. A LED serves as a tuning aid. 4 different filter shapes (or none) are selectable with one button.
This module is especially suitable for installation in the FT-817 transceiver. Due to it's small size it fits into the unit without sacrificing any space, say for the battery or similiar. The control button and LED are mounted in the upper cover of the FT-817.

NEDSP-1062 AF DSP Noise elimination module with amplifier

NEDSP1062 Amplified DSP Noise Eliminating PCB Module – This module incorporates an on board power amplifier and has an integral microcontroller connected to a small keyboard assembly. The microcontroller and keyboard provide single button operation of all the module’s functions. The module can be retrofitted into the speaker path of extension speakers like the Kenwood SP31, Yaesu SP8 and Icom SP20/21/23, or used to 'revive' your old receiver/transceiver by fitting the module into the speaker path of your equipment (space permitting). The module is supplied with Generic Instructions, a fused DC power lead, fitting kit and specific fitting guides for the Kenwood SP31 and Yaesu SP8. Requires 12-18V, includes cable and fuse.

NE-ANEM Noise Away module for direct integration before a loudspeaker

New DSP module with amplifier, for integration into the loudspeaker cable. No mechanical work required, just plug it into the cable to the external speaker and supply with 12VDC. Reduces noise in all modes, eight filters selectable, integrated amplifier, DSP bypass function (Off), can be installed anywhere with Velcro™. Necessary cables are included.

The ANEM unit was developed as a result of feedback from potential customers of the NEDSP1062-KBD pcb module. These customers felt that they did do not have the skills, or didn't want to drill holes into their beloved extension speaker or radio to fit the NEDSP1062-KBD. As a result of some market research, we decided to fit the NEDSP1062-KBD pcb module into a small black compact ABS box, allowing these customers to put the unit close to, under, or even fix the ANEM to their speaker by means of velcro (supplied with the unit). It also complemented the fully featured bhi NEIM1031 in-line module because the ANEM has just two push button controls for all the DSP functions, and is more of a "plug and go" unit, whereas the NEIM1031 is more of a "plug and play" unit, with separate controls for all the functions.

NE-1042 Loudspeaker/AF switchbox

Small switchbox with 6 inputs (three of them terminated to 8 Ω) and one output (or vice versa). For connection of several radios to one DSP loudspeaker. Connections 3.5mm phono plug, includes 2 cables 120cm.

NE-MINISW Mini switchbox

Small compact two-way switch box enabling the connection of two separate radios to your bhi DSP noise cancelling product:
Inputs: 2 x Mono 3.5mm Jack sockets. Output: 1 x 3.5mm mono jack socket & 1 x 3.5mm mono jack plug lead. Power handling: 3 Watts Maximum. Unused input is always terminated with a load to protect your audio outputs. Velcro pads are supplied to enable securing of the Mini Switch to your radio equipment.
