18.1 Useful hints

When using hard covers as back panel protection for the iPad, the Connection Kit's plug may

not fit completely, causing a loose connection or partial functionality. If in doubt, remove the

cover.

No sound: Incorrect output gain settings, see chapter 8.5.1.

The iPad's volume control is inactive during USB operation!

If the XTC is not recognized:

Remove and reconnect the

Connection Kit.

Correct detection and operation of

the Connection Kit itself can be

determined in Settings / General /

About. The adapter will be listed

there right after connection, with

additional details like

manufacturer, model number etc.

Connected USB devices, i.e. the

XTC will not be shown here,

though.

Having tested several chinese replicas of the Apple Camera Connection Kit, from 2-in-1 to

5-in-1 adapters, we strongly recommend purchasing the original for use with the XTC!

All adapters seemed to work for the simple application of copying photos. Attempting to run the

XTC with USB Audio 2.0 was when the problems started. Some of the tested adapters would

not work at all, others only with short cables, and only one adapter came close to the quality of

the original. But as soon as 8-channel recording or 96 kHz playback was initiated, the Apple Kit

always performed much better.

We also recommend the purchase of a dock-to-dock extension cable, to avoid having the

CCK attached to the iPad directly with the heavy USB cable hanging down.

This can cause the CCK to slip out of the iPad’s connector, or to be in the way most of the time.

An extension cable provides enormous freedom of movement. We are working with cable

lengths of 50 cm and 1 m, both work flawlessly. These cables are available as DeLock iPhone

extension cable, or Dock Extender, e.g. from Amazon.

It is important to note that each individual component is responsible for stable operation of XTC

and iPad. As an example, a setup with an iPad connected to a 1 m DeLock cable, CCK, 5 m

USB connection to the XTC only worked with the original Apple CCK. Not only for simple iTunes

stereo playback, but also with 96 kHz playback and 8-channel recording. In this setup, the USB

cable could even be replaced with a 10 m active one. With lower quality cables or CCK replicas,

even 50 cm dock to dock to 1 m USB would be considered success...
