The product price includes a one year warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

Comfortable During Performances

The Samson Airline 77 Vocal System E4 headset transmitter features the Samson QV10e Vocal mic element. This headset is designed to go around the back of your head rather than over the top meaning the transmitter can be attached directly to the headband, out of the way and comfortable during performances.

Cardioid Pickup Pattern

The QV10E is also designed with a unidirectional mic and cardioid pickup pattern that rejects feedback. The QV10e Vocal headset is ideal for singers who need hands free live performance because of the specially designed microphone element. The transmitter offers 14 hours of operation on a single AAA battery so you don't need to worry about it giving out before you do!

UHF Receiver

This system contains the CR77 true-diversity half-rack UHF receiver which is designed to work flawlessly with all AirLine UHF transmitters. Featuring dual tuned, moulded antenna, a front panel display with large segment audio level and RF level LEDs and a large rotary volume knob that allows easy adjustment of audio output. The synthesized PLL frequency control circuitry keeps the signal locked and true whilst the LED meters monitor the system's operation. The rear panel features balanced XLR and unbalanced ¼ inch outputs allowing multiple connection options.

It is possible to rackmount two CR77s together in a single space rack adaptor.
