Gold Line is pleased to offer the Model 7052PH from ACO Pacific Inc. DESCRIPTION The 7052PH is a phantom-powered measurement microphone system offering a cost-effective way to perform acoustic measurements. Designed to work with 18-48 VDC phantom power, the 7052PH system includes the 7052E Type 1.5tm microphone capsule (mic) and the 4048 ACOtron™ preamp. It works with pro audio interfaces (M-Audio, PreSonus, Lexicon, etc.), portable digital recorders, TEF20 and TEF25 analyzers that have phantom-powered 3-pin XLR mic inputs. The rugged Titanium diaphragm of the 7052E mic provides excellent long-term stability and temperature handling -- better than mics that use Polyester™ diaphragms. The companion 4048 ACOtron™ preamp features low noise and a wide dynamic range. .
