The NAD C 298 is a stereo power amplifier designed to deliver high-quality audio performance. It functions primarily as a power amplifier, taking a line-level audio signal and amplifying it to drive loudspeakers. The device is capable of operating in both stereo and bridged (mono) modes, offering flexibility for various audio setups and power requirements.
The core function of the C 298 is to amplify audio signals. It accepts both balanced (XLR) and single-ended (RCA) analog audio inputs, allowing connection to a wide range of preamplifiers, processors, or other compatible audio sources. In stereo mode, it provides two channels of amplification, suitable for driving a pair of loudspeakers. When configured for bridged (mono) mode, the amplifier combines its two channels to deliver a single, more powerful output, ideal for driving a single, demanding loudspeaker or for use in a multi-amplifier system where higher power is needed per channel.
The amplifier features a +12V Trigger IN/OUT system, enabling it to be remotely controlled by other compatible devices. The +12V Trigger OUT can send a 12V signal to turn on other equipment, while the +12V Trigger IN allows the C 298 to be switched on from standby mode by an external 12V DC supply. This integration simplifies system control, allowing for synchronized power-up and shutdown of connected components.
An Auto Sense feature is incorporated, which allows the C 298 to automatically switch from standby to operating mode when it detects an active input signal above a specified level. This provides convenience, as the amplifier can power on automatically when the source device starts playing audio. The Auto Sense level can be adjusted to Low, Mid, or High settings, catering to different source output levels and user preferences.
The C 298 also includes a LINE OUT feature, which allows for "daisy-chaining" multiple amplifiers. This is particularly useful in systems requiring more than one amplifier to drive additional speakers for the same channel, or for distributing the audio signal to other compatible devices like receivers.
The NAD C 298 is designed for straightforward operation. On the front panel, a Standby button allows users to switch the amplifier ON from standby mode or return it to standby. An associated Power indicator changes color (amber for standby, blue for ON) to clearly show the device's status. A Bridge Mode indicator illuminates blue when the amplifier is set to bridged (mono) operation, providing a visual cue for the current configuration.
On the rear panel, several controls facilitate setup and customization:
Speaker connections are made via robust terminals on the rear panel, designed to accept bare wire, banana plugs, or pins. Clear markings for Left and Right channels, as well as positive (+) and negative (-) terminals, ensure correct speaker wiring. In bridged mode, specific terminals (L+ and R-) are designated for the single mono output.
The NAD C 298 is designed for minimal user maintenance. The manufacturer advises against removing the cover, as there are no user-serviceable parts inside. Any servicing or repairs should be referred to qualified service personnel. This ensures the safety of the user and the integrity of the device.
For cleaning, a dry, soft cloth is recommended. If necessary, the cloth can be lightly dampened with soapy water. Users are cautioned against using liquid cleaners, aerosol cleaners, or solutions containing benzol or other volatile agents, as these can damage the finish or internal components.
Proper ventilation is crucial for the longevity and reliable operation of the C 298. The design incorporates ventilation slots and openings in the cabinet, which must not be blocked or covered. Adequate space around the unit (10 cm on left, right, and rear panels, and 10 cm on the top panel) is required to ensure proper airflow and prevent overheating. The amplifier should not be placed on soft surfaces like carpets or in enclosed spaces such as bookcases or cabinets without sufficient ventilation.
The device also includes a fuse holder, which is only accessible by qualified NAD service technicians. Attempting to open this fuse holder by unauthorized personnel may cause damage and void the warranty.
For environmental protection, the C 298 and its batteries (if any) are marked for separate collection and recycling at the end of their useful life, in compliance with environmental regulations. This promotes responsible disposal and recycling of electronic waste.
Overall, the NAD C 298 is a versatile and powerful stereo amplifier, offering robust performance, flexible configuration options, and user-friendly features, while emphasizing safety and proper maintenance practices.
