bhi DSP Noise Cancelling In-Line Modules
bhi DSP Noise Cancelling In-Line Modules eliminate noise and interference to let you hear more clearly! This new audio DSP unit cleans up noisy signals and works on most radios and receivers. It comes with the latest bhi DSP noise cancelling technology—which brings improved audio quality to the listener when operating in noisy conditions across all radio bands. The audio is clearer and more intelligible as a result. It's very easy to connect the In-Line Module between your radio and external speaker with the included 3.5mm male mono patch cable. This model delivers plenty of clean, noise-free audio with its 5W audio amplifier. The speaker output is muted when headphones are connected to the mono headphone output jack. When the unit is switched off, the audio bypass feature routes the signal directly through to the loudspeaker. bhi In-Line Modules provide simple control of all features. Their three-position switch turns the unit on and switches the noise cancellation on and off. The "Status" LED illuminates red when power is applied and changes to green when the noise cancellation is active. Set the radio AF gain to provide an audio input level that does not flash the overload LED. An audio output control adjusts speaker or headphone levels. Also included are a User Manual and four small rubber feet, plus the previously mentioned 3.5mm male mono patch cable for connection to your radio and a fused 2.1mm DC power lead. This unit may be powered by a user-provided 10 to 16V DC power supply or optional wall supply, BHD-PSU12-2A-WW. bhi In-Line Module features and specs: - Eight noise cancelling levels, 8 to 40dB - Tone reduction up to 65dB - 5W audio amplifier - Audio input overload indicator - Status LED indicates power and DSP operation - Audio bypass feature when switched off - Speaker output connection 3.5mm mono jack - Headphone 3.5mm mono jack - DC Input: 2.1mm center positive, requires 10 to16V DC @ 500mA min. - Dimensions, WHD: 5.315 x 2.559 x 1.811 in.

bhi LLC1 Stereo Line Level Converter
bhi Ltd LLC1 Stereo Line Level Converter enables you to use powered speakers with your EQ20 audio DSP unit. It converts your bhi EQ20 speaker level audio outputs to line level stereo and isolates the EQ20 Class D audio amplifier stage. This enables the connection of the EQ20 to powered speakers, an amplifier, or recording device. Background: The bhi EQ20 uses a Class D amplifier for efficiency and to reduce the need for heavy metal heatsinking. The only down side is that grounds or speaker outputs cannot be connected together as this may cause damage to the amplifier chip, which means that powered speakers cannot connected directly to the speaker outputs of the EQ20. The bhi Line Level Converter LLC1 converts the speaker level audio output of your bhi ParaPro EQ20 audio DSP unit to an isolated RCA line-level audio signal. This isolates the Class D amplifier stage from the line level output connection enabling powered speakers, an amplifier, or a recording device to be used with the bhi EQ20 unit. The LLC1 can handle the output from class D amplifiers designed for driving up to 10 watts into a standard 4 ohm or 8 ohm speaker. Connections: The LLC1 has an audio lead with two RCA phono plugs at one end for connection to the bhi EQ20 unit, and a stereo 3.5mm (1/8 in.) socket at the other end for the connection to powered speakers, an amplifier, or a recording device.

bhi Bypass Switch
bhi Bypass Switch is an audio bypass switch for the bhi Dual In-line and Compact in-Line DSP noise cancelling units, which don't have an internal audio bypass facility. When you switch the power off on these bhi units, the audio does not pass directly through to your external speaker. So, with the Bypass Switch, you can route the audio from your radio directly to your extension speaker without powering on your bhi unit. This can be particularly useful if you just want to listen to your radio without your bhi noise cancelling unit switched on. A single push-button switch on the Bypass Switch provides this facility. Press the button in and the audio routes through your bhi DSP noise cancelling unit (power on). Press the button again and the switch returns to the out position and the audio is routed directly from your radio and loudspeaker. bhi Bypass Switch features: * Complete audio bypass of bhi DSP unit * Latching switch: In--DSP audio, Out--Bypass audio * Four 3.5mm mono jacks * Two 3.5mm mono plug patch cables * Audio power 5 watt RMS max * Unit Dimension, WHD: 3.150 x 1.969 x 0.866 in.

bhi Ltd Ground Breaker
bhi Ltd Ground Breaker is an audio pass-through, RF blocking device that can solve the unusual dilemma of distorted audio bleed-through cause by RFI. First, you tried to provide a better ground system, wrapping the audio leads round ferrite rings, clamping ferrite beads onto the cables, running your systems on different power supplies, and you have checked the connections. If RF is still getting into the audio, the Ground Breaker may be the final solution. It totally isolates the ground of your accessory audio equipment from those of the radio system. Ground Breaker units come in impedances covering the main values of 10,000 ohm, 600 Ohm and 8 ohm that are used in most audio systems. Line level units can handle up to 100mW and the 8 ohm speaker units can handle up to 500 mW of audio. The Ground Breaker is simple to install. Simply plug the unit into the appropriate socket on your radio and then plug the audio accessory, such as the DSP or powered speaker into the socket on the Ground Breaker. The direction of connection doesn't matter; the unit works both ways with either the radio or the audio unit connected to the socket or the plug. Do not add extensions and try to keep the leads as short as possible to minimize RF pickup off the air. Sometimes, proper grounding of devices doesn't take care of that one nagging, RF bleed-through problem. In that case, use a bhi Ground Breaker audio RF blocking device from DX Engineering.
