The innkeeper LTD from JK Audio is a digital telephone hybrid designed for analog phone systems. The half-rack innkeeper LTD uses digital signal processing to keep caller signals separate from program signals.
Callers hear the program but not themselves and the XLR feed into the program and monitoring system carries the caller only. Digital echo-cancelling is also used to keep signals clean.
Signal separation can be up to 50 dB. Typical features such as auto-answer and drop switches are included. An auxiliary phone is required for outgoing calls. Two innkeeper LTDs can fit into an optional rackmount.
