The EMC of the PANDA target spectrometer is one of the central detector components to achieve the physical goals. The barrel part will consist of lead thungstate (PWO) crystals operated at -25°C to achieve the required performance over a wide energy range. To achieve a good energy, position and time resolution, it is necessary to perform detailed tests of prototypes. The most recent one, PROTO120, represents a subsection of the barrel EMC. The design is close to the final concept of the EMC with respect to the detector assembly, cooling circuit and front-end electronics. The conversion of the scintillation light will be performed with two rectangular LAAPD, which are read-out separately via the APFEL-ASIC providing a large dynamic range, low power consumption and the optimized shaping. The talk will describe the details of the construction and a first test on the performance based on cosmic muons. *Supported by BMBF, GSI and HIC for FAIR
