    Crossover Melt Down - Looking for an Explanation

    Hey all, hope I am posting this in the right place. We've all had our fair share of speaker and amp mishaps I'm sure, but I'm trying to make sense of something that happened the other night. I have a pair of Aerial Acoustic LR5 speakers. I had been driving them with a pair of mono blocked...

    Safely Using Pre Gain without Clipping

    I have a WiiM Ultra streamer as my main source. If I’m using ReplayGain for my Qobuz and personal library listening, but not the WiiM's room correction or PEQ, is it safe to apply some positive adjustment in the WiiM's Pre Gain control under Inputs without causing distortion or clipping? I use...

    Cleanest most Audiophile way to reduce preamp output by 10db

    What would, be the cleanest most pure way to reduce the output gain from my EAR 834P Phono stage (clone) from about 50db (seems to be the consensus on the output) to about 40db? So a reduction of about 10db. I’m fine with adding a high quality volume pot at the output sections but was...

    How important is transistor gain (HFE) in an amplifier?

    Without going into calculus, how important a role does the gain of BJTs play in the performance of an amplifier? I ask because I’m in the process of restoring a Harmon Kardon 330c and I’ve read in other threads that there may be “noisy” transistors in it. I don’t have golden ears, more like...

    What is the gain of a Marantz 2270

    Does anyone know the gain of a 2270 with calculations? I can’t find it on the spec sheet. I try to calculate it based on the rated output at 8 ohm but I get Gain = 100. That can’t be right, right?

    Line Level Attenuation and Volume Dial position - Discussion

    So, as the title suggests, I'd like to have a discussion about line level attenuation and volume dial position. Apologies if this has been discussed before. I did have a search, but didn't see anything specific. So here's some background that has prompted me to want to discuss this subject...

    Gain requirements: Ultra LOMC cartridges

    Hi all, In the past, I've used a selection of MM and MC cartridges. However, just recently, for cheap I acquired an ultra low output MC, a MC-20 by ortofon, and it needs a re-tip. The output is super low: 0.07mV. (This is the MK1 version, with the purple/blue body, circa 1980, much lower than...

    Fix Gain Pot With Diamond PC Thermal Paste?

    Hi i recently bought a preamp from a pawn shop. It works and everything the only thing is that the gain knob had to be pushed sideways to allow signal through i wasn't sure if it was broken. I didn't think so since i could get audio by maneuvering the knob. So i decided to clean it with contact...

    Gain matching for biamp

    Hi folks, I have acquired an ADS C2000 and will be looking to bi-amp some ADS L1230. I don't have a lot of knowledge on the demands I will be putting on the amplifiers. What I think is, as different program content puts demands on the amplifiers, they will respond accordingly and the output...

    Amplifier Gain Settings Question

    Hello everyone, I have a Hitachi Ha 610 that has three gain settings buttons below the stepped level attenuator. I've had this amp for a couple months but never really paid attention to these buttons. What exactly do they, I know they adjust gain but I'm still a little confused when it comes to...

    When I am guilty of the one thing I chastise others the most on, gain staging.

    I have been battling a odd problem with my system. Strange distortion behavior on certain high bandwidth tracks. I also run mixing boards for bands and churches, and nothing gets my goat as much as improper gain staging, seeing the trims set randomly and the sliders having unequal control...

    Question about gain and my chain of components.

    Howdy y’all, I’ve had new and very exciting changes/improvements to my system in the past few weeks and I’m not sure I’m utilizing these very powerful and awesome tools correctly. I’m hoping for an understandable explanation of gain as it applies to me and my system. As of right now, I’m...

    Output transistors subs with higher gain

    Hi, I've been wondering whether the gain of output transistors is critical if the subs have 2 to almost 3 times the gain of the originals and what changes should be done to compensate. I'm interested in this quesiton in a general case after trying to find subs for a Sony output stage using...

    Adjust MC2255 channel gain question

    Hi, I have been fine-tuning my very nice mc2255 amp. I have found that the gain on one channel is slightly higher (6%) than the other channel with both gain knobs set to max. I have cleaned both pots, but no change. I was thinking of adding a small resistor in series to the louder channel, but...

    Max cartridge output for MC input

    Hello, My current system has 2 turntables, plugged into a Harman-Kardon A402's two MM phono inputs. One table has an Ortofon OM cartridge with a 4mV output; the other has a Stanton 681 eee: moving iron, 0.7mV output. Right now both work fine (naturally, I have to crank up the volume when using...
