The TC 4042 is a spherical noiseless hydrophone. With its built-in 20db Preamp it offers a high sensitivity and is able to drive up to 1000m cable, like the TC 4032.
The Ambient TC 4042 is the allrounder within the Ambient hydrophone range. Not as sensitive as the 4032 but with an exceptional SNR it is perfectly suited for every sea-state and high peak levels. Due to its compact size the TC4042 will fit perfectly inside both the 20 cm and 30 cm Sonar Surround Directivity Spheres where the high-pressure zone in front of the Sphere compensates for the slight high frequency roll-off compared to the 4032. This makes it a premium choice for submarine multichannel recordings.
This hydrophone is so good that the export is restricted for some countries. Please contact us for detailed informations.
