System for recording from live source or dubbing to multiple tapes

A system for copying program signals from a master tape to a slave tape having a nonrecordable tape leader, comprising:

• master and slave drive units for master and slave tapes;
• a first head for reproducing program signals prerecorded on said master tape;
• a second head for recording program signals on said slave tape;
• and
• control means coupled to a control panel and said master and slave tape drive units and responsive to a panel selection of a dubbing mode of operation for energizing said master and slave drive units and controlling said first and second heads to copy program signals from said master tape to said slave tape;
• wherein said control means includes a delay circuit coupled to said master drive unit and operative during said dubbing mode to delay energizing only said master drive unit following a start-up of said system for a duration sufficient to enable the nonrecordable tape leader of said slave tape to bypass said second head;
• further comprising multiple slave drive units operable simultaneously by said control means to make multiple copies of said master tape program signals;
• wherein
• (a) said master and slave drive units are incorporated in cassette decks, including a microphone input;
• (b) said control means is responsive to a panel selection of a live performance recording mode of operation for recording live performance signals received through said microphone input onto cassettes in said multiple decks simultaneously;
• and
• (e) said control panel includes a first bank of switches for controlling said system to operate in the dubbing mode and a second bank of switches for controlling said system to operate in the live performance recording mode, and override circuitry coupled to said first and second banks of switches to override one or the other when switches of both banks are operated simultaneously.

A system for recording making multiple copies of program material derived from a live performance or a master cassette, comprising:

• master and slave decks for master and slave cassettes;
• a first head for reproducing program signals prerecorded on said master cassette;
• second heads for recording program signals on each slave cassette;
• and
• control means coupled to a control panel and said master and slave decks and responsive (1) to a panel selection of a dubbing mode of operation for energizing said master and slave decks and controlling said first and second heads to reproduce on said slave cassettes program signals reproduced from said master cassette, and (2) to a panel selection of a live recording mode of operation for energizing said slave decks and controlling said second heads to record on said slave cassettes live program signals received from a microphone;
• wherein said control panel includes a first bank of switches for controlling said system to operate in the dubbing mode, and a second bank of switches for controlling said system to operate in the live performance recording mode, and override circuitry coupled to said first and second banks of switches to override the recording mode of operation when recording mode and dubbing mode panel switches are operated simultaneously, so as to prevent recording on said master cassette.

A system for recording to multiple cassettes program material derived from a live performance or a master cassette, comprising:

• master and slave decks for master and slave cassettes;
• a first head for reproducing program signals prerecorded on said master cassette;
• second heads for recording program signals to said slave cassettes;
• a control panel having control means coupled to said master and slave decks and responsive (1) to a panel selection of a dubbing mode of operation for energizing said master and slave decks and controlling said first and second heads to reproduce on said slave cassettes program signals reproduced from said master cassette, and (2) to a panel selection of a live recording mode of operation for energizing said slave decks and controlling said second heads to record on said slave cassettes live program signals received from a microphone;
• said control panel including a first bank of switches for controlling said system to operate in the dubbing mode and a second bank of switches for controlling said system to operate in the live performance recording mode;
• and
• override circuitry coupled to said first and second banks of switches to override the recording mode of operation when first and second banks of switches are operated simultaneously, so as to prevent recording on said master cassette;
• each deck including a cassette lid pivotable open and closed, and a pack switch coupled to said lid for controlling the corresponding drive unit independently of the others.

• wherein said control panel includes control switches to commonly control multiple slave decks, and means for generating a control signal in response to operation of a control switch;
• said master cassette deck including an input terminal for receiving control signals from said control panel and an output terminal for sending control signals to a slave deck;
• and
• each slave deck including an input terminal for receiving a control signal from said master tape or another slave tape and an output terminal for sending control signals to a slave deck, and further including a control signal conditioning circuit for amplifying and removing spurious components from said control signal.
