This electronic preamplifier stands up to the test and will provide you with serious sound performance. The PP444 is perfect for bringing your studio equipment's phono-level output to a more suitable line-level output. It'll take your audio signal, amplify its strength and prepare it for further processing by your receiver or amplifier. Preamps technically provide voltage gain to your desired equipment and are key to assisting the signal source, whether it's a turntable, musical instrument or microphone. The ultra-low noise audio conditioning circuitry allows the preamp to boost audio to levels that are more manageable for various types of audio equipment. You'll find it easier to adjust the recording level volumes of different sources from microphones and instruments alike. You should position your preamp close to the source to reduce unwanted noise and interference.

GOgroove Mini Phono Turntable Preamp Preamplifier with 12 Volt AC Adapter , RCA Input for Vinyl Record Player - Compatible With Audio Technica , Crosley , Jensen , Pioneer , 1byone and More Turntables

Model: 4330356298   |    Mpn: GGAAPPA100BKUS   |    Ean: 0637836597901   |    PartNumber: GGAAPPA100BKUS   |   Asin: B00WNLIHJA

Integrate the Old with the New

What Does a Phono Preamp Do?
A phono preamp boosts your turntable's phono audio level up to a more speaker/stereo receiver-friendly line level , giving you better volume and increased sound quality. If you're planning on hooking up your turntable to a computer , stereo receiver , bookshelf speakers , or any other modern audio equipment , you're going to want this preamp to get the high sound quality that you expect from vinyl.

Do I Really Need It?
Most likely , you do. The majority of newer stereo receivers and speakers lack a phono input , which would directly connect them to the turntable. You'll need the preamp to connect to the phono output of the turntable and the line input of the receiver/speakers. And even newer turntables that may feature a built-in preamp probably aren't going to give you the highest quality sound that could be achieved from an external preamp.

Quick , Easy Setup
You don't need to be a sound engineer or techie to understand this preamp's setup process. It takes only a minute to power up the preamp with it's included 12 Volt DC Adapter. After that , it's just a matter of using RCA cables (NOT INCLUDED) to hook the preamp to both your turntable and your stereo receiver , speakers , or other audio device.

Works With:

Audio Technica AT-LP60BK , AT-LP120BK , AT-LP3BK
Crosley CR8005D-BK , CR6233D-BK

ViewHD HDMI Audio Receiver Extractor | Optical Toslink + L/R Stereo Analog Converter Outputs | 1080P 3D | Model: VHD-H2HSAs / VHD-H2HSAi

Model: VHD-H2HSAs   |    Mpn: VHD-H2HSAs   |    Ean: 0608819811826   |    PartNumber: VHD-H2HSAs   |   Asin: B00KBHX072

The ViewHD audio extractor (model VHD-H2HSAs or VHD-H2HSAi) supports Amazon FireTV, Roku, AppleTV, Chromecase, DVD player, cable and satellite STB, etc. Please make sure the AV receiver can support the specified audio formats to have sound.

This ViewHD HDMI extractor has one HDMI input, one HDMI output, one SPDIF / optical output and RCA L / R stereo audio output.

It can extract digital 2CH PCM stereo audio signal from the HDMI input and convert it to 2CH analog stereo output through its RCA style L/R analog output. The RCA L/R output will not have sound if the incoming audio is multi-channel audio (>2CH). Set EDID switch to 2CH for RCA L/T stereo application.

The SPDIF optical audio output supports all audio formats up to 5.1CH Dolby Digital 5.1CH / AC3, DTS 5.1CH formats. TOSLINK optical audio output does not support higher formats, such as Dolby TrueHD, DTS-HD Master Audio, PCM5.1 and beyond.

The HDMI output has identical video and audio signals as the A/V signals coming into its HDMI input, no modification.

Not recommended for DVI display application, unless the HDMI source can allow users to specify RGB color and disable deep color, to avoid video format conflicts with many DVI displays, DVI color space trouble typically introduces pink and green screen or no picture. PS3, PS4 and PS4Pro are the most user friendly HDMI sources to fix DVI compatibility issues.

Package includes:
Audio Extractor, Universal 100V - 240V AC to DC 5V1A Power Adapter with US plug & User Manual.

Application tips:
Set audio EDID to 5.1CH for DD5.1CH / DTS5.1CH, use optical output to connect to audio receiver for surround sound.

HDMI output supports all formats including PCM5.1CH and beyond.

For 5.1CH PCM or above, set audio EDID to pass, connect HDMI output to receiver directly.

If no video, do: 1) power up the TV, 2) power up this extractor, 3) Power reset the HDMI source unit. Or connect the HDMI source to the TV directly and use manual settings for all video related options, then put the extract in between.
