Hi all
I came to know about an old IC called probably "HE100" which was being used in DIFAR Sonobuoys for generation of composite signal. This IC takes 'Omni', 'Sin and Cosine Dipoles' signals as input and generates composite signals using internally generated 7.5 KHz and 15 KHz carriers. This...
Hi all
I need to design a band pass filter of 14 KHz bandwidth (3dB) such that its centre frequency can be varied from 80 KHz to 900 KHz by some means e.g. tuning voltage. Is there any commercial IC available for such application? If not, how can i design voltage controlled band pass filter...
Currently we have National Instruments digitization system for real time data acquisition & streaming. Do we have a option to synchronize multiple preamplifiers devices and to use their digitized outputs real time?
Hi, I am bothering you again with another 8-channel preamplifier rack i.e. TASCAM SERIES 8p Dyna microphone preamplifier with analog compressor . I have attached its manual here. In this manual, at page 9 &17 it talks about D-sub 25-pin connector for analog outputs and TRS jacks for Line...
Hi all
A guy from another forum has suggested my Behringer "ULTRAGAIN DIGITAL ADA8200" 8-channel microphone preamplifier. I have attached its data sheet here. Kindly help me whether this module will meet my requirement of independent preamplified outputs?
Thanks
During search on net, i came across dBx profession audio preamplifier "TR1616". Its manual is attached with this post. Its manual, says that it has 16 analog IOs. From this what i understand is that it has 16 independent analog inputs with which i can connect 16 transducers and it has 16...
Thanks for reply. The acoustic transducers operates in 5 KHz to 13 KHz frequency range and act as transreceiver i.e. both transmit and receive. Each transducer has input impedance of 500 Ohm. Each transducer can handle upto 330 Vrms but we know we are not getting any COTs solution in reasonable...
Hi all
We are planning to develop an experimental test setup for 32-channel acoustic transducers array and for that purpose, we require 32 channel Power Amplifiers (PAs) and Preamplifiers available in COTs. We need to simultaneously drive 32 transducers using PAs and similarly simultaneously...
Thanks. I will try them

Do i need to introduce inductor only in positive supply line or in ground line also? Should i connect capacitor b/w + and - supply terminal of SBC? Thanks
Hi all
I am driving a preamplifier in frequency range of 3 KHz to 40 KHz with 60 dB Gain with 12V DC Power Supply (R&S bench power supply). The noise floor at preamplifier output observed on oscilloscope is around -60dBV (in frequency range of 3 KHz to 40 KHz) when input is being short...
Hi
If we take example of D1650 PA, it has specifications of 50W across 8 Ohm load i.e. around 20 Vrms across 8 Ohm load. 1/100 of rated power means 0.5W across 500 Ohm load i.e. 15.8 Vrms across 500 Ohm impedance transducer. Am i correct in my calculations?
Hi all
I want to drive 16-channel low frequency acoustic transducer array using commercially available audio power amplifiers. The input impedance of single transducer varies from 500 Ohm to 700 Ohm at 8KHz. The two commercially available 16 channel models i searched are "D1650 Digital...
Hi all
I am searching headphone with a specific connector type "Lemo FFP.2S.310.CLAC42" . I also need to know how audio signals from/to headphone are connected on this Lemo 10-pin connector? If anyone has information about such product please share with me?
Regards
The signal cable is Flexible 150 Strands 0.08mm of Tinned copper wire having impedance of 20m ohm/meter.
Currently i have interface ADC with a FPGA to store data as well as to generate control signals. Now, how to proceed further for data transfer over 500m cable was my initial query.
