QUAD 44
¥ 210,000 (around 1986)
Commentary
Control amplifier with module configuration.
All input / output terminals of QUAD44 are modularized and can be replaced as needed.
Equipped with tilt control and base control, it can respond to changes in characteristics depending on the listening room and speakers.
The tilt control adds gradual changes throughout the frequency band without changing the overall level.
The base control consists of a LIFT position and a STEP position. The LIFT position is used to smoothly increase the low-frequency characteristics of small speakers, and the STEP position is used to cut howling when speakers are installed on walls or corners.
Phono Input has 5 types of modules to support all MM/MC cartridges.
In addition, matching with the cartridge is handled by replacing the module.
There was a separately sold wood case named sleeve.
