Audio Technica ATM250DE Dual-Element Instrument Microphone
Audio Technica ATM250DE Dual-Element Instrument MicrophoneDetails
The Artist Series new kick-drum mic, the ATM250DE dual-element instrument microphone features cardioid condenser and hypercardioid dynamic capsules combined in a single housing. Audio-Technica's innovative use of two polar patterns is ideal for kick drum: the hypercardioid dynamic element focuses tightly on the aggressive attack of the beater, while the condenser captures the round tonalities of the shell.

The elements are positioned in a perfect phase relationship, something practically impossible to achieve with two separate microphones. Includes a professional isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted mechanical noise.
The ATM250DE is intended for use in professional applications where remote power is available. It requires 11V to 52V DC phantom power only to the condenser output of the supplied cable.
Output from the microphone's 5-pin XLRM-type connector is low impedance (Lo-Z) balanced. The included 5.0 m (16.5') shielded cable features a 5-pin XLRF-type input connector and two standard 3-pin XLRM-type output connectors. The balanced signals appear across Pins 2 and 3 (condenser) and Pins 4 and 5 (dynamic). Pin 1 is ground (shield). Output is phased so that positive acoustic pressure produces positive voltage at Pins 2 and 4.
To avoid phase cancellation and poor sound, all mic cables must be wired consistently: Pin 1-to-Pin 1, etc.
An integral 80 Hz hi-pass filter on the condenser element provides easy switching from a flat frequency response to a low-end roll-off. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically-coupled vibrations.
The ATM250DE's condenser element is also equipped with a switchable 10 dB pad that lowers the microphone's sensitivity, thus providing higher SPL capability for flexible use with a wide range of performers and system configurations.
The ATM250DE includes an AT8471 isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted mechanical noise.

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 6 years from the date of delivery.
- Our Money Back guarantee is extended from 30 days to 180 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 6 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 2 years warranty.
