We present a concept design for a versatile, high throughput fiber couple spectrograph for the 9-meter Hobby-Eberly telescope. This instrument, designated the medium resolution spectrograph (MRS) will cover the visible spectrum from 350 nm to 1100 nm and have a resolution range 300 < λ/Δλ < 20000. It will reside in an environmentally controlled spectrograph room. Operating modes of the spectrograph will include single object, synthetic long slit, and multiple object spectroscopy. The dual requirements of spectral coverage and high resolution mandate that the MRS be a dual beam instrument.
