Citronic D2400 2 x 900W Class-D Amplifier

The Citronic D2400 is a stereo power amplifier built around Class-D circuit architecture, converting power efficiently for cool, reliable operation even under sustained high-output use — the kind of demand a busy bar, gym, or event venue places on an amplifier over a full night's running. Custom cool guide technology keeps that efficiency consistent, while an inbuilt limiter circuit engages automatically at peak output to protect connected speakers from overload.

Flexibility comes from switchable parallel and bridge modes, selectable input sensitivity, and a 75Hz low-cut filter, allowing the D2400 to be configured for a wide range of sound reinforcement setups rather than locking the installer into a single fixed configuration. All of this is housed in a compact, lightweight 1U rack chassis, keeping the amplifier practical for installations where rack space is limited.

2. If you have not requested a return within 28 days of receiving an order, we will have assumed that you are intending to keep it and we will not authorise a return.

3. We always refund the payment according to how the original purchase was made and aim to do so within 72hrs of the return being received by us.

4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.

5. Delivery charges will not be refunded unless the delivered goods are faulty.

6. Replacement products are dispatched immediately after the returned goods have been received and accepted by Inta Audio.
