Get to know them!

The affordable Samson MDA1 is your ticket to clean, rich sound on a budget. Whether you need a faithful guitar signal to re-amp in the studio, or a discreet way to send your bass guitar or synth to front of house, the Samson MDA1 does a commendable job for the price. It includes a Thru output to go between your instrument and amp without coloring your sound. The Samson MDA1's custom transformer reproduces frequencies all the way down to 18Hz, and its rugged, noise-rejecting chassis stands up to nightly abuse and noisy conditions. The MDA1's -15dB attenuation switch keeps hot signals from overloading your DI.

  • Custom STL transformer is rich and dynamic
  • Steel chassis is built for the road
Custom STL transformer is rich and dynamic

Samson's custom STL transformer sounds great in the MDA1. The STL covers the full audible spectrum and beyond, able to capture all the subharmonic richness of a synth and high-end detail of an acoustic guitar and carry it noise-free to your mixing board or interface.

Steel chassis is built for the road

The Samson MDA1's 14-gauge steel housing resists noise and stage abuse to keep your events running smooth night after night. Sweetwater knows sound professionals can expect years of performance from their Samson MDA1.

  • Converts an unbalanced, 1/4" instrument-level signal to a balanced, XLR line-level signal
  • 15dB input attenuator prevents overloading from hot signals
  • Sends bass guitar, synthesizer, or acoustic guitar to a mixer/recording console
  • Makes an affordable front end for studio re-amping and guitar modeling

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
