| Use Battery Backup For Preamp and TT? Most cheap battery back up units, when in the inverter mode, put out a square wave not a true sine wave.Square wave sucks.....A "True UPS" will put out a true sine wave. They are costly though....Found this doing a search on Googlehttp://www.jkova... | |
| Balanced vs standard power I'm curious about how incoming line harmonics would compare between a system with electronic tap switchers vs a sola system, maybe not an issue unless the o.p. went with multiple smaller units that could potentially be 'talking' to each other or h... | |
| Need to use my 220v preamp in 240v. You will need to use a transformer. Two choices, you can use a cheaper autotransformer or an isolation transformer.Step down the voltage at the existing wall outlet from the nominal 240V to 220V.If you are thinking about using the existing 240V ci... | |
| Help using integrated as power amp Whats wrong with the preamp in the Arcam? If it is the tuner section section in the receiver you wish to still use from the receiver, use the tape output of the receiver connected to a line input of the Arcam. | |

| System Hum Question However, when I disconnect the inputs from the preamplifier (and leave the other end connected to the amplifier), the noise in my speakers gets louder. Why is this?No doubt.... Don't do that. Having the ICs connected to the amp but not connected t... | |
| disc player/transport longevity I bought a Denon DCD 1500 CD player in 1988. My daughter still uses it to this day. It has never been serviced.I am still using an Arcam Alpha 9 I bought in 1999. | |
| New Ground Loop - What Could Have Caused? It was the Verizon FIOS box. Once I disconnected IC's running from FIOS box to pre, problem solved. No music stations through stereo, though.08-29-11: NglazerNglazer,Is it? Or is it actually caused by a difference of potential between the shield s... | |
| New Ground Loop - What Could Have Caused? Nglazer,Somewhere outside your house there should be a grounding block for the Verizon FIOS incoming cable before it enters your house. The ground wire that connects to the ground block is supposed to connect to the main grounding electrode system... | |
| New Ground Loop - What Could Have Caused? including Verizon FIOS box and TV,If it is indeed a ground loop hum problem I would start with isolating the CATV coax cable from the Verizon FIOS box. Disconnect the coax from the box, check for hum.If the hum is gone buy a ground isolator and in... | |

| Stylus Riding Too Low? Kldonne,Here are a couple of videos that might help.Watching the videos it appears the arm is higher at the back than at the front with the stylus resting in the record groove. Did you remove the three shipping transport screws?Make sure there is ... | |
| Stylus Riding Too Low? I noticed that the rear of the tonearm is actually so low that it touches the album as it progresses so that seems to be the cause.That can't be right. Sounds like the VTA at the pivot is too low.Are you sure the platter is seated down properly on... | |

I have an Audience Adept Response R12 power conditioner that displays the voltage from the wall. It is normally 112-114 during the day and up to 117-118 in the evening. It is currently a... |
