RDL STA-1 Dual Balanced/Unbalanced Line Amplifier, Up to 20 dB Gain in an Audio Line, Conversion from Balanced to Unbalanced, Conversion from Unbalanced to Balanced, Conversion from High to Low Impedance, Conversion from Low to High Impedance, Bridge an Audio Line Feed, Precisely Match Audio Levels

The STA-1 is a dual-channel line-level preamplifier with bridging inputs, adjustable gain or loss, and low-impedance outputs. Each of the two identical circuits is both an electronic line transformer and a line amplifier. Hook up the STA-1 just like a pair of audio transformers with gain. True dc amplifiers produce unsurpassed audio clarity, high common-mode rejection, ultra-low distortion and low noise. The STA-1 is perfect for most line amplification, impedance or balanced/unbalanced conversion.

The STA-1 operates from floating or bipolar dc power. For installations where ground-referenced power is preferred, use the STA-2A Dual High Gain Line Amplifiers.

    Returns / Exchanges & Refunds

    30-Days Return Guarantee

    1. Returning/Exchanging
    If your product arrives defective or damaged, try refusing delivery from the Carrier. That will allow us to ship a replacement unit quickly. If refusing delivery is not possible, contact us and we will send you instructions for the return/exchange. Please do not return a product until you receive the Return Authorization (RA#) and instructions from us, as the product might end up lost if returned without an RA#. In such case no refund will be possible.

    2. Time allowed for Returns
    If you need to return a product for any reason, you can do so but you have to report the issue and request the return within 7 days of receipt and the return has to be postmarked within 30 days of receipt of the original shipment to you. After 30 days you will need to contact the Manufacturer directly for Warranty Repair.

    3. Condition of Returns
    In order to make a return, the product must be in NEW condition, with the ORIGINAL BOX, all the Accessories, Paperwork and Packing Materials intact, exactly as you received it.

    4. Shipping & Handling Costs
    If the return is due to our error, we will pick up the product at our expense. If the return is for any reason other than a fault of our Company, the actual shipping and handling costs (both ways) will be your responsibility. If you do not like a product or no longer need it, this is not considered our fault and we will not issue a shipping label for the return. If you ship the product at your expense please insure it for the full value of the order.

    5. Restocking Fees
    If the return is due to our error, the product was damaged in transit or DOA (Dead On Arrival), no restocking fee will apply and we will refund 100% of the item's price.

    If you refuse delivery or decide to return a product because you changed your mind, no longer need the product, have buyer's remorse, found a cheaper seller, you don't like the product or the product doesn't fit your needs, a restocking fee will apply:

  • Any unopened item in original condition: We will refund 80% of the item's price.

  • Any item that is not in its original condition, is damaged, or is missing parts or original packaging for reasons not due to our error: Depending on the condition of the item received, we will refund from 50% to 70% of item's price or we could also return the product to you and not refund anything if the product is in bad condition or missing important parts.

    6. Refunds
    Refunds can take 5-10 business days from the date the item returned was received by us or by our supplier.
