Full DescriptionView Full Description
The 4050a features a number of tools to minimize distortion and protect speakers. This includes channel-independent clip limiters and high-current toroidal transformers. Additionally, its 30/50Hz low-frequency filters block out inaudible but potentially equipment-damaging frequencies.
- Compact size - up to 2500 watts in two rack spaces, or 5000 watts in three rack spaces
- High-current toroidal transformers, for greater 2-ohm power and low noise
- Independent user-defeatable clip limiters reduce distortion
- Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
- The 4000-watt RMX4050a operates on a standard 15 amp plug (120V)
- Both the RMX4050a and the RMX5050a feature a dual mono, high-current power supply for increased reliability and performance
- The RMX4050a's particularly exceptional combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications.
- Balanced 1/4" (6.3 mm) TRS, XLR, and barrier strip inputs
- Touch-proof binding post and Neutrik Speakon® outputs
- Front mounted gain controls for easy access
- Signal and clip LED indicators for monitoring performance
- Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers

The product price includes 2 years' 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 2 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.
All Products are new unless stated, and include a minimum of one year warranty.
This offer excludes computer software, in-ear monitors that have been opened, and items supplied to your personal specification.
If you also purchase items that do not qualify for free delivery, some delivery charges may be applied to your order which will be shown in your shopping basket.
