Getting the Basics Right

When it comes to Classic Series amplifiers, no feature is overlooked. Low noise circuits, precise volume control action, and accurate channel balance are all key characteristics of the C 328. With the added bonus of proper input and output impedance traits, plus high overload margins and stability with difficult speaker loads, the C 328 is the best choice for audiophiles who are just starting to build their dream systems. The C 328 also includes a MM phono stage with precisely correct RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs—all without affecting bass response.

 

ANALOGUE IN/HEADPHONE OUT

• Continuous output power into 8 Ohms
  and 4 Ohms
• 50W (ref. 20 Hz-20 kHz at rated THD, both channels driven)
• THD (20 Hz – 20 kHz)
• <0.005 % at 1 V out
• Signal-to-Noise Ratio
• >100 dB (A-weighted, 32 ohms, ref. 2V out, unity gain)
• Frequency response
• ±0.3 dB (20 Hz – 20 kHz)
• Output impedance
• 11 ohms

ANALOG IN/SUBWOOFER OUT

• THD (20 Hz – 20 kHz)
• <0.005 % at 1 V out
• Signal-to-Noise Ratio
• >100 dB (A-weighted, 32 ohms, ref. 2V out, unity gain)
• Frequency response
• ±0.2 dB (20 Hz – 20 kHz)
• Output impedance
• 200 ohms

ANALOG IN/SPEAKER OUT

• THD (20 Hz – 20 kHz)
• <0.03 % (100 mW to 40 W, 8 ohms and 4 ohms)
• Signal-to-Noise Ratio
• >95 dB (A-weighted, 500 mV input, ref. 1 W out 8 ohms)
• Frequency response
• ±0.3 dB (20 Hz – 20 kHz)

PHONO IN/SPEAKER OUT

• THD (20 Hz – 20 kHz)
• <0.03 % (200 mW to 40 W, 8 ohms and 4 ohms)
• Signal-to-Noise Ratio
• >75 dB with IHF MM cartridge (A-weighted, ref. 5mV input 1 kHz and 1W output in 8 ohms)
• Frequency response(RIAA deviation)
• ±0.3 dB (20 Hz – 20 kHz)

 
Note:The RIAA response is consistent with a pre-emphasis that is rolled off at 50kHz by a second order filter, such as used in Neumann cutting lathes.
