CAVS JB-199 mini II is a new ultra compact karaoke player with a built-in web server. It is the latest of JB-199 mini series and thanks to the web server, customers can connected to the player using any standard web browser. For example, a customer with an iPhone or iPad can connect to the player using the Safari browser. A customer with Android phone or tablet can connect to the player using the Google Chrome. Once connected, the customers can select, reserve, and play the songs in the karaoke player

Having a web server, the JB-199 mini II can also simultaneously play and stream the audio video outputs. That is, it will play through TVs and speakers as before and at the same time stream to the connected phones and tablets. The phones and tablets can then play the music and lyrics working as the satellite karaoke players. The customers can now carry the phones or tablets and enjoy the karaoke at pool sides, on decks, or in cabins.

The JB-199 mini II comes with comprehensive professional features following the tradition of JB karaoke series. It has the basic functions such as Pitch control, Tempo control, Sync control, Pre amp, Silence gap remover, etc. It has the advanced tools such as History, Announcement, Digital Mixer, International Interface, Advertisement, Bill acceptor, etc. It is based on Intel NUC architecture harnessing the power in a compact 4.6″ x 4.4″ x 2″ chassis.

The JB-199 mini II supports unlimited number of karaoke songs in CD+G, MP3+G, ZIP, AVI, MP4, and Super CD+G formats. It organizes the songs using a Playlist concept so that each song can be searched or played instantly and yet stored securely from accidental removal or overwrite. It also offers data encryption for added security and time lock for subscription management which can both be controlled remotely.

E-Songbook is a device such as a phone or a tablet that connects to a karaoke player to select, reserve, and play the songs. Until now however, the E-Songbook required an app to connect to a karaoke player. And since the app was hardware specific, a different karaoke player or a different phone or tablet required a different app. This complexity discouraged customers from using their phones and tablets and led to the karaoke hosts providing the E-Songbooks pre-installed with apps on the tables.

The E-Songbooks were also prone to connection failure, delays, and incompatibility. The connection failure came from non-standard app designs. The delays came from increasing contents. The incompatibility came from exploding varieties of new phones and tablets in the market.

The built-in web server of the JB-199 mini II solves the all problems above. The E-Songbook can now connect using a standardized web browser such as Apple Safari, Google Chrome, or MS Edge. It no longer requires individual apps. The connection follows the TCP/IP protocol, is fast and efficient, and supports all new and old models of phones and tablets.

With the ease of connecting, the customers can use their personal phones and tablets as the E-Songbooks. It is no longer necessary for the hosts to provide the pre-installed E-Songbooks on the tables. The cost saving starts immediately and continues for not having to replace the pre-installed tablets when they are dropped or drowned.

As options, the JB-199 mini II provides multiple privilege levels at which the E-Songbooks can connect. The lowest is to browse the songs but without the access to reserve or play the songs. The highest is to access all which is usually reserved for the Admin. Each level can be customized for your need.

A karaoke player typically plays the audio and video through the HDMI, VGA, or RCA outputs. The lyrics show on a TV and the music sounds through the speakers.

The JB-199 mini II with a built-in web server however can simultaneously play and stream the audio and video outputs. That is, it can play the music and lyrics as before and at the same time stream the audio and video to the phones and tablets. The phones and tablets can then play the music and lyrics using their own displays and speakers.

The customer interface that appears when a phone or tablet connects to the JB-199 mini II is as follows.

It is a karaoke player in a shell. It can select, reserve, and play the songs as well as control the pitch, tempo, and voice channel. And it can play the music and lyrics on its own.

A phone or tablet can thus become a satellite karaoke player having the controls, music, and lyrics when connected to the JB-199 mini II. And a customer using such a phone or tablet can enjoy the karaoke anywhere. A home owner, for example, can enjoy the karaoke in bedrooms, upstairs, outdoors, etc. A cruise guest can enjoy the karaoke at a pool side, on a deck, or in a cabin. The customers are no longer tied to a player or a location.

Online Karaoke
The online karaoke offers opportunity for people who are apart to get together online for karaoke fun. For example, the families who are spread across the states can join together for the holidays. The friends who are out of the country can get together for a karaoke party.

The JB-199 mini II can accommodate 10, 20, 30, or even 50 such customers connecting together online. And to each, it will send out the customer interface, music, and lyrics. It will also send out face to face meeting invites using Zoom, Skype, or Google Team SNS. Instead of driving to a local karaoke lounge, the customers are asked to join together in a face to face online karaoke party

The customers of the online karaoke party can sing solos, duets, quartets, or all together. The music and lyrics will be of sharp high quality directly streamed from the JB-199 mini II to each customer. For a free trial, go to CAVSKaraoke.com..
