Earthquake Sound iQuake IQ-52B iPod Dock


The Design

The iQuake consists of two speakers, one of which has an iPod connector on top (see photo above). There are no grille covers.

The rear panel has lots of connections for flexibility (photos below).

Besides the iPod input slot on top, there is a pair of RCA analog input jacks and a 1/8" stereo phone jack. Since the iQuake has a volume control, you can connect the stereo analog ouputs from a CD player, a TV, or whatever other source you have. The Input Selector button is used to select which set of input jacks you are using. There is a volume control knob, but 99% of the time, you will be using the remote control for that purpose. Note that the remote controls the volume in the iQuake directly, it does not adjust the volume setting on the iPod.

The iPod connects to the iQuake with a digital bitstream, and there is a DAC inside the iQuake for decoding into analog.



The iQuake has two 100 watt power amplifiers (Class D) inside, so there is plenty of power. In fact, because of their size and power, you could useseveral sets of these speakers connected to a surround sound processor for home theater use (connected with the RCA jacks). The cable that connects the two speakers is quite long, so you would have no problem extending the speakers to either side of a large HDTV. This cable is basically a speaker cable as both power amplifiers are in the main speaker enclosure.

The woofer is 5" and made from carbon fiber. This is a very high tech material that is increasingly used in speakers. However, notwithstanding the high tech woofercone material, you still need a subwoofer if youwant deep bass. You can use the subwoofer output jack on the rear panel of the iQuake, or if in a surround system, just use the sub-out on your processor.

If you have a Video iPod, the S-Video output jack on the rear panel will send the videosignal to your TV.

The USBjack lets you connect the iQuake to your computer for sync with your music in your iTunes library, so if you add music to the library, it will automatically upload to your iPod as it sits in the dock. TheiQuake also recharges the iPod while it is in the dock. (Various sets of cables come with the package for the various connections discussed.)

The AuxAC outlet is for a wireless accessory module (optional) that will allow you to connectto your network and play music from your PC into the iQuake.

The included remote control operates from 32 feet away and gives you complete control of the audio system, and also control of the iPod itself (although you might have a little trouble reading the iPod screen from across the room!)


So, now you see what I mean about the feature set distinguishing this product from most of the others out there. It's not the cheapest iPod dock, but what is the point of exchanging listening through good earphones to listening through a cheap speaker that has audible distortion?
