Legacy 6-82759 SD90Mac NS #7230 engine sound is too low

Raven87OGR Forum Member SUPPORTING MEMBER

I have two of the Legacy SD90Macs, Norfolk Southern models, #7245 (6-82760) and #7230 6-82759). Both are great engines and are basically identical - except that #7230’s engine noise is about HALF the volume of #7245’s!
The horns, crew talk, and bell sounds of both are of very equivalent volume. But the engine noise level difference is striking.
I’ve checked the volume knob (yep, fully cranked), speakers (no debris etc), but nothing makes a difference. If both are idling at the same time #7245 will easily drown out #7230. It’s bizarre.
One reason I bought #7230 was because I love the sounds of #7245, especially the engine sounds. But #7230 seems meek compared to #7245! Yet, the crew talk, bell, and whistle the same as #7245?
Why is this? I took videos of both and I’ll try to post them asap.

It sure has me puzzled…

You might try this:

So, when connecting via bluetooth, you also ensured you raised ALL volume controls to max right?
You click on the speaker icon from the home page when connected

Here are two vids. The difference doesn’t seem quite as much but #7245 is clearly much louder at idle. Could a previous owner have somehow set the engine noise volume lower but left the other sounds at normal volume? I’ve never heard of that but I’m new to the Legacy features game.😉

Ideas?

Doing it with TMCC or Legacy from the manual https://www.lionelsupport.com/...782761250SD90MAC.PDF

Remember most legacy supports Aux1 + volume to adjust prime mover and background sounds.

Page 16 of manual

When adjusting the overall volume, you'll hear a single bell hit that gets louder or softer
with each volume adjustment. When the volume is at maximum, additional button presses
have no effect and won't play the bell. When adjusting the background sounds (AUX1, then a
volume key) you'll hear the prime mover volume change without a single bell hit

Thanks Vernon! I never thought of that so I’ll check that first thing.

I never adjusted anything and just got #7230 today. I did adjust the volume on the CAB remote and the overall volume changed with the single bell sound accordingly but everything came down and up together. I never thought of the Aux 1 button.

But - I bet you nailed it. I’ll let you know tomorrow!

I never used the Bluetooth Lionchief App. I only use the Legacy Remote. i’m not sure these units have Bluetooth? It doesn’t say it on the box.
Thanks!

I’m also learning that Aux 1 button adjusts the sound and I just confirmed myself .

Raven87 that engine doesn’t have Bluetooth, it would be listed on the box (awesome engine btw)
