  KIC 4150611 is a high-order multiple composed of a triple system composed of
the F1V primary (Aa), which is eclipsed on a 94.2d period by a tight 1.52d
binary composed of two dim K/M dwarfs (Ab1, Ab2), which also eclipse each
other; an 8.65d eccentric, eclipsing binary composed of two G stars (Ba, Bb);
and another faint eclipsing binary composed of two stars of unknown spectral
type (Ca and Cb). In addition to its many eclipses, the system is an SB3
spectroscopic multiple (Aa, Ba, and Bb) and the primary (Aa) is a hybrid
pulsator. We employ a novel photometric analysis of the complicated eclipse
geometry of Aa to obtain orbital and stellar properties of the triple. We
acquired 51 TRES spectra at the Fred L. Whipple Observatory, calculating radial
velocities and orbital elements of Aa (SB1) and the B binary (SB2). These
spectra and radial velocities are used to perform spectral disentangling for
Aa, Ba, and Bb. Spectral modelling is applied to the disentangled spectrum of
Aa to obtain atmospheric properties. We obtain precise stellar properties of
the triple, including the mass ratios (MAa/(MAb1 + MAb2) = 3.61 +/- 0.01,
MAb1/MAb2 = 1.113 +/- 0.001), separation ratio (aAab/aAb1Ab2 = 21.81 +/- 0.01),
orbital periods (PAab = 94.29486 +/- 0.00008d, PAb1Ab2 = 1.522248 +/-
0.000001d), and stellar radii (RAa = 1.64 +/- 0.06 Rsun, RAb1 = 0.42 +/- 0.01
Rsun, RAb2 = 0.38 +/- 0.01 Rsun). Radial velocity fitting and spectral
disentangling arrive at orbital elements for Aa, Ba, and Bb in excellent
agreement with each other and with previous results in the literature. Spectral
modelling on the disentangled spectrum of Aa provides constraints on the
effective temperature (Teff = 7280 +/- 70 K), surface gravity (log(g) = 4.14
+/- 0.18 dex), micro-turbulent velocity (vmicro = 3.61 +/- 0.19 km s-1),
rotation velocity (v sin i = 127 +/- 4 km s-1), and metallicity ([M/H] = -0.23
+/- 0.06).
