1/28/2024 0 Comments Passive vs active reamp![]() It's a choice everyone should make for themselves. ![]() You may be looking for 'effect boxes' (the preamps that are said to be more musical to some) that may have tube amplification or LDR volume control. There are also passive amplifiers (so there is some gain) but this requires extra care with the connected loads. hi fi, phantom powered, high impedance (1MO or 10MO) instrument buffer. But they are used for the purpose of matching levels and impedance. The Red Eye 3D Phantom is a passive direct box/re-amp box with unique expansion. In all other circumstances a good active one is preferred for reasons already stated by others. Some DI boxes can function as a preamp if they a fitted with built-in preamp. When you don't need more gain and don't need to switch between XLR and RCA then a passive one might be a solution. In both cases one can choose between stepped (or relay) or stepless. If yes consider: A good pre-amp is better than a passive one.Ī passive (volume control + input selector) can be better than a mediocre or poor pre-amp.Īn active pre-amp and some passives require mains voltage. If you can answer with at least one yes you do need a pre-amp. And most analog pots, even the good ones, have some degree of channel imbalance at low volume settings, and are noisier than metal film resistors of equivalent resistance.ĭo you need more gain than just 1x ? (power amp/speakers not reaching clipping levels as it is)ĭo you need / want a physical volume control ?ĭo you need balance and tone control (on more than 1 input) ?ĭo you have a mix of RCA and XLR inputs / outputs ?ĭo you want to add 'effects' (think tubes, LDR volume control etc.) ? A passive attenuator can give you that 30 dB reduction with a smaller drop in SNR. If your listening level is 30 dB below max, the SNR might only be 80 dB. The preamp spec might say for example 110 dB SNR but that is at max volume which nobody uses. So when you turn down the volume, the SNR drops with it. The fitted mute switch is also handy for cutting the signal to any connected amps while you move or swap mics. Most active preamps have an analog stage that has a fixed gain ratio with attenuation. The nicer more expensive ones have 48 or more steps with finer spacing.Īs I see it, the most relevant benefit of the passive is that it preserves SNR and perfect channel balance even as you turn down the volume. The volume you want may be between steps. The cheap ones have 24 steps which are typically 2 dB apart which is a lot. Also, a passive using stepped attenuators only gives you discrete volume levels. An active preamp is more flexible and buffers the devices from each other, so you don't have to worry so much about impedance matching. A passive that doesn't meet the above conditions can be worse than an active. IF all of your upstream devices (sources) have low output impedances, all your downstream devices have high input impedances, unity gain is more than you need, the attenuator's resistance is as low as possible but not too low (10k works in most cases), and you can use short cables. I'll bet you can find it with search.Ī passive using stepped attenuators of metal film resistors can be more transparent than an active preamp, under certain conditions. The passive Reamp HP features quarter-inch TRS and 3.5mm mini input connections, transformer isolation to eliminate ground loops and variable output control to optimise signal levels.There's another recent thread on this same topic with lots of opinions & advice for you. The Reamp HP is a compact device that accepts a signal from the headphone jack on an audio interface, making it easy to connect. The unit also features reamp level control, a filter and mute switches. Radial Engineering Reamp JCR Passive Studio Re-amping Device New. a 48V LED indicator signals if the unit is receiving phantom power. Inputs include a quarter-inch TRS and 3.5mm mini-plug for connecting mobile devices and tablets. Improvements to the active DI design include a unity-gain Class A buffer switch and circuit on the Thru output, which Radial say helps preserve guitar tone when using passive pickups. The Reamp Station is Radial’s first all-in-one recording and reamping solution, combining the JCR reamper and a studio-quality active DI circuit into one unit. The rights to his design were purchased in 2011, which led to Radial launching the legendary Radial JCR. Radial’s new Reamp Station is based on the designs of pioneering reamp engineer John Cuniberti, who built the first reamp box in 1993. The Reamp Station is an all-in-one active DI and reamp device and the Reamp HP is a compact mono reamp box that can receive the headphone output of an audio interface as its source. ![]() Radial have released two new reamp solutions, their first new reamp product launch in years.
