Hi Alain,
for the purpose you describe it is a good choice. You can prepare all work at home on the 7000, save to SD, and play back on the transportable 2600, including audio tracks. The 2600 has equalisation in the same way, so you can tweak the sound or balance for any external monitors you have. The 2600 sounds are similar to the 7000 sounds, you just have to remember not to use any of the 7k soundcard sounds in the setup, or those sounds in the 7000 explorer that do not appear on the 2600, then there will be no surprises on playback!
