Author Topic: Audio Inputs to USL 105/195 Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 11-16-2005 01:07 AM                     I have the audio for my on-screen ads going into the "EXT" input of the Ultra Stereo 105/195.The audio is coming direct from the sound card of a PC(Volume on PC turned up full) but the sound level is not loud enough without having to adjust the main fader which we don't want to do all the time.There does not seem to be any way of increasing the volume like you can with the Non-Sync trim pot.Any ideas on how to overcome this problem?

You may have some resistors place in line with that input with the 5/95 since the sensitivity of the N/S is quite high and the resistors cut down the input current of certain N/S source devices. thx-Monte  |  IP: Logged Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 11-16-2005 03:23 AM                     Hi Monte Yes the volume of the PC is turned to full. This USL is a 105/195-a newer model to the 5/95. The trim pot is used for the Non-Sync input which I have my background music playing through. The audio for my on-screen ads is connected to the EXT input which does not have a trim pot for adjustment. I'm not sure whether the EXT input has a higher input impedance than the Non-Sync which would cause my reduced volume or whether i need a small pre-amp to boost the signal to the EXT input.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-16-2005 07:13 AM                     Then you may have to use an inexpensive external mixer of sorts to boost that level and allow you to have contol of that level seperately. That input needs a line level signal and apparently your audio card is not capable of delivering that.

That input needs a line level signal and apparently your audio card is not capable of delivering that. If you want to use the non-sync input then just place a 50 to 100k stereo pot in the line to have control of that, mount the pot on a single rack plate above the processor.

The mixer you describe will work perfectly. Alternatives are any form of stereo line amplifier such as an RDI #STA-1 with 20 db of gain. www.rdinet.com Louis  |  IP: Logged Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 11-16-2005 08:26 PM                     Thanks guys-I thought I may need an in-line amplifier.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

Try that first and see if it gives you enough level without audible distortion. Your PC may also have some kind of "sound effects" or "media effects" control program installed which essentially all do the same thing.  |  IP: Logged Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 11-17-2005 06:44 PM                     Thanks Michael That is definitely worth trying before I look into an in-line amplifier.
