1U 19″ rack-mountable quad amplifier with 4 input channels and 4 independent speaker outputs. Each output can deliver up to 60W to either low impedance (4 or 8 ohm) or 100V speakers by connecting either the upper or lower screw terminals on the rear panel. An internal media player can play audio files from a USB pen drive, tune to FM radio stations or connect via Bluetooth® to a smartphone for wireless playback of stored audio tracks. A paging mic input has switchable Vox function to override other channels. 2 further balanced inputs can be selected to accept mic or line level input with switchable phantom power. Channels 1 to 3 also each have Bass and Treble controls for tone adjustment. A separate line input has RCA or screw terminal connection and, if required, can be switched to serve the internal media player. Each of the four inputs can be selected to any or all of the four output zones, each with a separate output level control and line level output for expanding to further amplifiers or powered speakers. An optional CS4 call station may be added if specific area paging is needed, providing a fully independent and flexible zoning system for background music, recorded information and announcements.

Delivery Exclusions

PLEASE NOTE:

Some products are exceptionally large, heavy or bulky and require specialist freight services. This typically includes items such as large PA speakers, dual 15″ speaker cabinets, dual 18″ subwoofers, flight cases and other oversized or very heavy equipment.

We work hard to keep our prices as competitive as possible and, in most cases, delivery is completely covered by our standard shipping rates. However, for certain oversized items being delivered to regional or outlying areas, the actual courier cost can be significantly higher than standard deliveries. This is also owing to factors completely outside of our control (petrol costs and rising costs of delivery by courier partners)

If this applies to your order, we will always contact you before dispatch to discuss the available options. These may include:

Proceeding with a small additional freight contribution.
Collecting the order from one of our suppliers or a nearby courier depot where available.
Cancelling the order for a full refund if a suitable solution cannot be reached.

Please be assured that we only request an additional freight contribution in exceptional circumstances where the courier cost is substantially higher than normal. Our goal is always to deliver your order at the advertised price whenever possible.

If you’re unsure whether an item may be affected, you’re welcome to contact us before placing your order and we’ll gladly provide a delivery estimate.

Thank you for your understanding and ongoing support!
