Tape / CD Switch

A Simple Solution to a Common Problem

• Interfaces a tape record/playback deck to a monaural sound board as typically found in church applications.
• Contains a built-in resistive stereo to monaural combiner circuit.
• Designed for a line-level (10K) unbalanced interface.
• Positively prevents the creation of a feedback loop through the recorder by eliminating the possibility for record and playback signal paths to be opened simultaneously.
• Eliminates the necessity for using separate record and playback decks.
• Increases versatility by permitting multiple decks (when available) to be used for both record and playback.
• Permits the selection of only the left or only the right channel for use with split-track tapes where the music is on one channel and the vocals are on the other channel.
• Permits the selection of left plus right where both channels of a stereo tape are combined into a single monaural signal.
• The left plus right position can be used to combine music and vocals on a split-track tape for practice sessions.
• The record position disables both playback channels and routes the mixer output to both left and right record inputs in order to produce a monaural recording.
