Professional Portrait on Location

Will uses a Pilot to control a remote Trio, inside the street level broadcast booth and a Qflash around the corner for dramatic effect.Next Will moves inside and sets his Trio to manual. He uses the Pilot to remotely tweak the Trio’s power until the radio personality’s portrait is lite just right.

Child Portrait – Outdoors
Will uses Trio’s high speed sync capabilities and a really cool mulitiple Qflash bracket to shoot in bright sunlight and capture some nice child protraits.

Action Shot with Rearcurtain Sync
Will uses Qlash to freeze the action and rear curtain sync for motion effect to capture this image of a bicycle racer on the streets of Chicago.

There is a diagnostic fee of $35 per item being submitted for out of warranty repairs. This fee shall be waived should you proceed with the repair.

A limited 90 day warranty applies to all repairs and all equipment that passes our diagnostic test. Our service goal is to get our customers up, running, and taking pictures with their Quantum products quickly!

When a product is returned to us for service, it receives more than a simple check.

First, the serial number is checked against a list of updates to the product line for any improvements we made to current production, which will improve the performance of an older model.

For battery products, Quantum technicians test the charger, the charging circuit, and check for any anomaly. Circuit updates are then performed as needed. A final performance check must be passed before shipping the unit back to our customer.

The batteries (internal rechargeable cells) are not off-the-shelf stock items from our suppliers. Quantum performs its own performance check and rejects battery cells that do not meet the manufacturers’ or our specifications for capacity, longevity, and chargeability.


Please include the product serial number in your correspondence regarding any problem you are having with a Quantum product.

* Also include:*
* Your name and complete mailing address.
* Your daytime telephone number and time you may be reached.
* Your email address.
* Specific information regarding your inquiry and/or detailed description of a problem.

Equipment Be sure to include

Repairs are done on a first come first serve basis and could take up to twenty business days depending on our work load. You will be contacted, with an estimate after a tech has evaluated your equipment. Once the estimate is approved the work will be completed within 2 business days and your equipment will be sent back.

*Please note: *
Paying by check will delay the return of your repair until the check has cleared (up to 15 work days) which could be beyond our normal turn around time of ten to fifteen business days.
