NAD has always had a formidable reputation when it comes to quality, budgetamplifiers. The NAD 3020 in its various guises, and more recently the NADC320 and C340 all have received world-wide accolades for their outstandingmusical performance and superb value. As an encore NAD is proud to pre-sent a new amplifier, further enhancing that reputation: the C350.Features:The C350 is fully remote controlled and comes supplied with the NAD CSeries system remote control. As the C350 has NAD Link the remote controlwill also operate many other NAD products such as CD players, tuners, etc.Flexibility is another NAD strong point. The C350 has 7 line inputs (including2 tape in/outputs with dubbing facility) and the pre-amplifier section can beseparated from the power amplifier for easy upgrades or adding ancillaryequipment. Thus the C350 can be expanded to meet future system needs.The C350 sports 2 pre-amp outputs: Many systems benefit from the use ofmultiple power amplifiers for "Bi-Amping" (using separate power amplifiersto drive the bass and treble section of a loudspeaker). With the second Pre-out 2 facility an extra power amplifier, such as NAD's forthcoming C270which has identical amplification factor (gain) as the C350's power amp sec-tion- is easily connected.For remote on/off switching of ancillary components in a system, such aspower amplifiers or active speakers, the C350 is equipped with a 12V-triggersystem. When switching the amplifier on, the 12V- trigger output is also acti-vated which in turn can activate a 12V-trigger input and switch on the remotedevices. Besides the 12V-trigger, the C350 also has an AC switched outlet(North American version only) so you can easily switch your entire systemon or off with the remote control or from the front panel.It is fashionable to omit tone controls nowadays: However, provided that thetone controls are properly designed, they can be really useful tools in makingimprovements to the overall sound. The C350 tone controls only work at thefrequency extremes leaving the critical mid-band essentially unaltered. The tonecontrol circuits can be completely bypassed by using the tone defeat switch.The C350 also incorporates NAD's acclaimed switchable "Soft Clipping" cir-cuit, which significantly reduces the risk of damage to loudspeakers due toprolonged high power operation.Design: Impedance Sensing Circuit (ISC):The C350 also benefits from NAD's proprietary Impedance Sensing Circuit(ISC) topology, now well established and used throughout the NAD productrange notably in the highly reviewed models such as the C320 and C340. TheISC topology allows the C350 to deliver maximum performance under virtu-ally any circumstance, independent of the loudspeakers it is driving. The cir-cuitry automatically senses the impedance characteristics of the loudspeakerand will then adjust its power supply settings to best cope with that specificload. This also gives it an unusual characteristic compared to traditionalamplifiers when measuring its continuous output power; the RMS outputpower remains the same at 60 Watts with either an eight or four ohms load.This is not unusual for NAD however.NAD takes a stance to the mindless "brochure power" approach which doesn'tgive a realistic indication of an amplifier's true capabilities. Instead, the ISCtopology is a practical approach to enable an amplifier to easily deal withdynamics and difficult loads. More meaningful are the C350's dynamic capabil-ities; up to 240 Watts into 2 ohms and up to 55 amps peak current capability!Other design features include relay input switching (located right behind theinput sockets for short signal paths) and the large Toroidal transformer (lessmechanical hum and stray magnetic field). The generous power supply andover-specified output devices further lead to low noise and low distortion forthe entire amplifier. Like all the other in- and output sockets, the Pre-out/Main-in sockets are gold plated for long-term contact reliability. Theheadphone socket will drive virtually any non-electrostatic headphone.C350 Stereo Integrated Amplifier• 60W x 2 Continuous Power into 8 ohms • 135W, 190W, 240W IHF Dynamic powerinto 8, 4 and 2 ohms, respectively • Impedance Sensing Circuit (ISC) topology• Full System Remote control including Stand-by/Off • Headphones socket• Relay Input Switching • Toroidal Power transformer • 7 Line inputs, includingtwo tape in/outs • All discrete circuitry • Short signal path from input to output• All sockets Gold plated • Tone controls defeat switch • Main-amp input& 2 pre-amp outputs • Soft ClippingTM • NAD Link • 12 volt trigger output
