Speaker Wiring
Connect the 2-wire speaker cable to the speaker wiring cable provided. The speaker output audio is produced from a stereo mixer circuit fed into a mono bridged audio power amplifier capable of delivering up to 3W of continuous average power to the speakers. Connect the RED wire to both the RIGHT and LEFT speaker connections, and connect the Black wire to the speaker AGND. This provides consistent audio from both speakers while allowing the use of High- Off-Low volume levels.

Folder numbers must be sequential, with no skipped numbering. During disc map, the folder # is displayed as “Mapping Disc #42” A 100 folder memory card would typically take about 4-Min to map.

Warnings
- Folder names can only be a two digit number from 00 to 99.
- To the wallette, this folder number is also the disc number, and must be in sequential order with no skipped disc numbers.
- A missing number, such as 06 above, will cause the Disc Map process to end at disc number 05 allowing only 00-05 to select.
- Reduces Mapping time instead of always looking for 100 discs.
- Each folder can have up to 99 songs, 001-099.
- The song file format can be MP3 or WAV.
- The first three numeric digits of the filename identify the song track position and must be sequential starting at 001 up to maximum 099, the selection range for CD audio tracks.
- Any characters after the digit numbers are ignored, but can be used to identify the song.
- The example above shows song tracks for folder 00, which is disc 00 for the wallette.
- So, if you want to play the song “Snowbird”, you would enter “0008” on the wallette.
Just a Note …
I haven’t seen Rock-Ola CD Wallettes on eBay for quite a while. In fact, last time I contacted a previous seller, he told me “They were just an expensive Night-Light” without the jukebox. Well, not any more. I think these Wallettes are really nice. They look great, sound good and you no longer need a jukebox. Don’t have the 24VAC Wallette transformer ? We use the wall plug-in type, search for MGT2450P From my years of producing these type of products, I’ve seen prices soar on Wallboxes. But I truly believe this Wallette will do the same. And I think it’s time to put them up “For Sale”. Customers are waiting !
