I am not really familiar with Bluetooth receivers but assume you are picking off a signal into the Bluetooth receiver for listening/monitoring on an external Bluetooth enabled device.
The W1 contact is one of several Playback/Record contacts. If I understand the circuitry correctly, when the W relay is energised it is then in Playback mode, where the ECC81 output at C22 is switched by W1 to the Playback equalisation components. With the W relay de-energised it is in Record mode and the C22 output is switched by W1 to the EM84 Magic Eye for record signal monitoring.
Sorry but from your information I cannot really advise much else from what has already been said.
