1/4" TS to XLR Hydrophone Preamplifier

18dBV Gain, active phantom power preamplifier

Aquarian SKU: PA1dX
$45.00
  • Connects passive hydrophones (like the H1a) or high-impedance instruments (piezo contact mics, electric guitars) to standard consumer microphone inputs
  • Utilizes the same trusted, low-noise buffering circuitry found inside the popular H2d hydrophone
  • Runs on the Phantom Power supplied by your recording device (24V or 48V) eliminating the need for external batteries or extra power cables

NOTE: This amplifier is not waterproof.

What's Included:

  • 1/4" TS to XLR Hydrophone Preamplifier

Simply connect the hydrophone to the adapter and the adapter to the mic input of your audio device. Phantom power is required and will need to be enabled, either with a physical switch or within the menu system of your audio device.

Phantom power is an option with most professional-grade audio devices with microphone inputs. 48 volts (P48) is the original standard by which most manufacturers comply, but the need for lower power consumption in battery-powered devices, along with simplification of design, led to other standards. This module should work with any available phantom power supply, but performance may vary with alternate standards. If options for phantom voltage are available in your device, select the lowest voltage available to minimize noise and power usage. The following specifications are based on use with IEC P48 phantom power.

20 Hz to 20 kHz unweighted, RMS voltage, unless otherwise noted:

Gain 18 dBV 1
Noise < 20µV 10nF shunt
Response +0 / -1 dB
THD <0.1% 2
Input 6.3mm TS 3,4
Z in 300 KΩ 4
Max input 250mV 1 10% THD
Output XLR male 4,5
Z out 6.8 KΩ 1

1 Specs will vary with non-standard phantom power supplies.

2 Class “A” operation offers soft clipping at high amplitude and distortion is not noticeable at normal amplitudes.

3 Standard connector—also referred to as 1/4” mono phone plug.

4 Can be modified per user requirements.

5 Full-size 3-pin, pin 1=GND; pin 2= hot; pin 3=unused (single-ended output)
