Hi all,
I Have been using the audio trigger in the Halo A51 five channel Amplifier for music and movies, paired with a Halo P7 Stereo/Multichannel Analogue Preamplifier. The Audio trigger's sensitivity is rated between 50mV to 250mV and only through Input 1 of the A51 as per the manual. But in actuality Inputs 1 and 2 are capable of triggering the A51
The Left channel is connected to Input 1 of the A51 and it triggers on when the volume is about 43-46 on the P7 while playing Stereo music. But the A51 turns off if the volume is 38 or lower on the P7.
Input 2 on the A51 is connected to the centre channel for 5 channel movie watching the volume on the P7 needs to be 60 or above to trigger the A51. But this is too loud for normal movie watching and the Volume on the P7 has to be lowered to about 50-53 for comfortable listening. In movies where most of the sound is in the form of dialogue(Centre Channel) the A51 turns off after a few minutes.
My query is the following:
Is there a way to increase the sensitivity of the A51 Audio trigger from 50mV down to about 25-35mV(or any advisable level)? Will I have to Change the Potentiometer or make changes in one of the Resistors connected to the Potentiometer on the Audio Trigger PCB?
Thanks in advance for you replies.
