Recommendation and specification of audio and video gear is an included service in most design packages and the recommendation includes your preferences.  Review what’s included with each package at this link here.  If however after design completion, you decide to change the recommendation by your own choice or due to the recommendation of an AV Integrator, our collaboration in that discussion is considered an extra service and may result in a design change order.  We refer to it as Equipment Selection Consulting and is available to purchase as a 3 hour flat service with extra time available at our billing rate.  Using components other than the ones we envisioned can change some fundamental aspects of the design and a successful high performance system is always our goal.
