McIntosh C12000 Hybrid Preamplifier

The C12000 is comprised of the C12000 Controller module and the C12000 Preamplifier module. All power control, data ports, and external control connections are located in the C12000 Controller. Dual isolated power supplies drive the left and right channels, while a dual microprocessor gives robustness to the control system. The C12000 Preamplifier houses the audio connections and circuitry. Inside each, the left and right channels are electrically and mechanically isolated from each other to allow true dual mono operation – resulting in the ultimate stereo separation and sonic purity. The two units are connected together via a pair of specially designed, high performance umbilical cables that are shielded to prevent outside noise from leaking into the audio signal. Although they are two separate units, when connected they act as one and are easy to control and operate from the included remote control or the C12000 Controller front panel.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.
