Background and Identification
The Grace Digital Mondo saw its release in 2011. With a clear color LCD screen for navigation, as well as combining a 3-inch subwoofer with a powerful 1-inch tweeter, the Mondo has been a popular Grace Digital product, even as newer and more powerful internet radio platforms have been released. It is distinguished by its division, with the left half devoted to its speaker systems and the other half devoted to user input. It also has a cavity on the rear for an optional battery pack add-on. Go to the Official Product Page to get a feel of the product and company.
The device itself has a smooth, polished texture. The casing can be very difficult to open due to the design. It has an LCD screen in the middle of the right side, and the left edge of the right side of the product is a column of buttons, bordering the speaker area. The speaker area is a blank black fabric, with the only design being a logo near the bottom of the speaker cover. There are only 3 screws visible from the exterior of the product, and two of them are sunken so as to not be immediately obvious. Still have more user questions? Go to the Mondo User's Guide to see how the device work's and frequently asked questions. Reviews of the Grace Digital MONDO are also found on their Amazon Product Page.
The ear phone jack can wear out, I found a replacement
I use my Grace Digital Mondo with ear phones very often, and it finally stopped working, in that it would cut the speaker off when plugged in, but one day it did not restore the speaker when I unplugged it.
After taking the Mondo apart, and separating the two boards, the one with the display has the ear phone jack. It can be easily taken out by anyone with good soldering skills. I used a hot air tool that I often use on surface mount parts, but you can easily solder suck the pins to remove the old jack.
The replacement part that fit like a glove, came from Digikey. With the help of one of their parts locators, I measured the parts pin spacing and general description, and the part I got fit like a glove. Part # CPI-3525NG-ND
This part will not have gren on the neck, but it will do everything the old part did, and fit perfectly in the board. My mondo is back in service. The part cost under a dollar.
