Know before you buy
The C32 features a 12-watt-per-channel monitor amplifier that allows you to drive a pair of small speakers or headphones directly. This is particularly useful for monitoring your audio source or recording process without needing to power on your main power amplifier.
Yes, the C32 is equipped with two dedicated phono inputs. This makes it an excellent choice for audiophiles who run multiple turntables or have different cartridge setups they want to switch between easily.
The front-mounted 5-band equalizer allows you to fine-tune specific frequency ranges to compensate for room acoustics or personal preference. Because it is a vintage analog design, it provides a tactile way to shape your sound signature without the need for digital signal processing.
This specific unit has been completely overhauled and restored to ensure it meets its original performance specifications. While it is built to the high standards of 1970s McIntosh engineering, it is always recommended to keep the unit in a well-ventilated area to protect its internal components.
The C32 provides a maximum gain of 62 dB for the phono stage, which is generally sufficient for many moving magnet and high-output moving coil cartridges. If you are using a very low-output moving coil cartridge, you may need an external step-up transformer to achieve optimal volume levels.
Yes, you can connect modern digital sources like DACs or streamers to the auxiliary RCA inputs. The C32’s input impedance of 50k Ohms is well-suited for the output levels of most modern consumer audio equipment.
