A control amplifier with the same basic configuration as 44 but with a different number of input terminals.
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.
The QUAD34 has phono inputs, tuner inputs, tape inputs, and auxiliary inputs.
MM and MC can be used for phono input by changing modules.
In addition, matching with the cartridge can be handled by replacing the module.
There was a separately sold wood case named sleeve.
