I'm using a T-amp with only speaker level outs. It is fairly common to find power amp input stage clipping voltages of 4 Vrms (+14 dBu). Home. Eight speaker outputs with up to 160 Watts RMS @ 2 Ohms, two processed RCA outputs for the connection of additional amplifiers, six RCA and eight highlevel inputs with up to 32V RMS input sensitivity and an optical SPDIF input make this amplifier absolutely unique in its class. These will boost or cut the low frequencies and high frequencies. So, if the input sensitivity is +4 dBu, the sensitivity control can be set at -10 dB re. If the input sensitivity isnt lowered on a higher voltage input signal there is a strong risk of clipping and distortion at higher volume levels. The sensitivity rating tells you how many dB the speaker will produce with 1 watt. I've got the Input Sensitivity set at -10dBv on the 305, which I think is the right setting for a Focusrite Scarlett 2i2 using TRS-XLR cables. Turn the input sensitivity control on the amplifier all the way down. My thought was since my headunit does 4 volts that I should set the amp to 4 volts. For example, an amp with 500mV input senstivity will only need 1/4 the output of a normal 2V CD player to reach full power! Input sensitivity is the maximum voltage strength of an input signal that an amplifier can handle and still produce unclipped full output. This is important to understand because not all audio signals have the same voltage. And, when a signals voltage exceeds the input sensitivity of an amp clipping and distortion can occur. In the world of speakers and speaker design, speaker sensitivity refers to how loud a speaker will be given a specified signal input of 1Watt. 68 mm Slim fuselage, installed under the seat. JL Audio Help Center - Zendesk Sponsored. My head unit is the JVC KD-R988BTS This head unit claims 4 volt preouts. Calculating Amp Input Sensitivity - Craig Vecchione's Live Sound & Production - Harmony Central By mikekars, March 28, 2014 in Craig Vecchione's Live Sound & Production Your studio monitors might have settings for LF- and HF- Trim. The rated input sensitivity is 1.2 Vrms (approximately +4 dBu). maximum sensitivity to make the amplifier clip when driven at +14 dBu. So, with an input of one watt (usually white noise), a speaker with a sensitivity of 90 db/Wm will produce 90 decibels of sound at a distance of one meter. The only reason for the speaker level inputs being there is so you can use the sub with an older receiver that doesn't have a subwoofer line level output. the input sensitivity of the speakers amp, can be adjusted from 1V to 2V. This is usually specified for a loudspeaker in a non-reverberant environment, in dB SPL and referenced to 1 meter on the reference axis with an input of 2.83 volts RMS, typically at one or more specified frequencies (often 300, 400, 500, 600Hz or the average of these). Sensitivity should always be accompanied by an impedance specification. Choose whichever settings suit your taste, but make sure that these settings are the same on both speakers. Disconnect the speaker (s) from the amplifier. Volume control For example, some speakers have a sensitivity of around 81 dB or so. Equipment Forums. Speaker Sensitivity. Speaker sensitivity is a measure of how loud a speaker will play at a given input power or at a given input voltage. Sensitivity is normally measured with a 1 watt power input or a 2.83 Vrms voltage input. The acoustic output is normally measured in an anechoic space at a distance of 1 meter from the speaker. So since the preouts are pushing 4 volts (according to JVC) I set the 'input sensitivity' of the Kenwood amp to {4} for both input sensitivity knobs. However, what this means is that it's related to the number of volts out, nothing to do Input sensitivity is indeed by convention related to rated output in watts into 8 ohms. Thanks for the info. What is Sensitivity in Speakers? This means that the speaker measured 97dB SPL from 1 meter away with a signal of 2.83 Volts. The input sensitivity setting in Genelec speakers is defined as the level of the input signal required for 100 dB SPL at 1 meter distance. I rarely have the Scarlett turned up much past halfway. This means an active Sensitivity is usually measured with a microphone connected to a Set the source unit volume to 3/4 of full volume. It is a measurement of the amount of sound output derived from a speaker with one watt of power input from an amplifier. Power output: 21W (per speaker) 42W total. Lets assume you have three speakers lined up with the following sensitivity rating: Speaker A:85dB Speaker B:88dB Speaker C: 91dB. Sony STR-D865 AV Receiver Amplifier Tuner Dolby Surround Digital Phono Input. Know This Before - Greatest Input Sensitivity Settings You may also find an Input Sensitivity switch on your studio monitors. Typical sensitivity for a PA loudspeaker is 95 to 110 dB-SPL/watt/meter. Installed a KSC-SW1 sub woofer today in my Prius with JBL option. The equation for the sensitivity of a speaker is expressed as: S = 20 log 10 (P/P ref) Quantities P and P ref are the sound pressure produced by the speaker under test and a reference sound What is Input Sensitivity? The input sensitivity setting in Genelec speakers is defined as the level of the input signal required for 100 dB SPL at 1 meter distance. At this distance, most speakers at a given input of 2.83 volts will have an If there is a sensitivity range switch, set it to the low position. Place a microphone in front of the speaker, about 3.3 feet (1 meter) from the microphone. Input sensitivity: 500 mFFS (optical) 450 mV (Line in) Those are powered speakers so the only way you could blow them is if they are defective be design, or you feed them an overpowered analog signal. Forums. 97dBSPL, 2.83 Volts, 1Meter. This only shows that the amp gain structure is different with the two inputs, which is of no consequence. The speakers are connected to an Interface (UA Apollo 16) with Output of 20dBU. So if you set the sensitivity setting 1 x Active Subwoofer. In this case there is no headroom for peaks, so youll have to drive the speaker at less than its full rated power if you want to avoid distortion. This means with one watt of power, they'll deliver just a moderate listening level. What is input sensitivity on speaker? Sony STR-GX69ES Receiver Amplifier Dolby 5.1 Pro Logic Surround. $335.00. It is measured as a voltage. Cables, Power, Tweaks, Speakers, Accessories (DBT-Free Forum) Thread starter Technopiper; Start date Apr 15, 2018; Tags sensitivity speakers Apr 15, 2018 at 6:02 AM Thread Starter Post #1 of 3 Technopiper New Head-Fier. the maximum voltage strength of an input signal that an amplifier can handle and still produce unclipped full output. 1 x Subwoofer High Level Input Line. You'll Speaker input sensitivity: lower or higher? The HELIX Extension Card slot (HEC) allows adding. + $113.02 shipping. So if you set the sensitivity setting to the So the math goes like this: 1w = 80.4dB 2w = 83.4dB 4w = 86.4dB 8w = 89.4dB 16w = 92.4dB 32w = 95.4dB 64w = 98.4dB 128w = 101.4dB I have the volume on the back of my 305s turned right down to 2.5 (!! That way the speaker wont be damaged if the amp clips by overdriving its input. Sony STR DH500 5.1 Channel 100 Watt Surround Sound AV Receiver. High level Input Sensitivity: 0.9v. Use the RCA input. $79.95. A sensitivity of 90 is considered average, with ratings of 87 and below considered low sensitivity and above 93 considered high sensitivity. For example, your DC sub has a sensitivity rating of 80.4 dB, and can handle 300w RMS. Then for every doubling of wattage, you add 3 dB. The rated amp gain is 34.5 dB Therefore for a sine wave @ 1.2 Vrms, the output voltage will be 63.7 Vrms or + $47.20 shipping. ), and I control the volume from the Scarlett. Turn off all processing on the source unit and the amplifier (bass/treble, loudness, EQ, etc.). And in the later case, they would probably just clip and distort, not fail. Sensitivity is a totally different factor that has to be considered separately before purchasing your speakers. To put it simply, the sensitivity of a speaker means the ability of the speaker to convert power into volume. In other words, this refers to the amount of power required in order for your speaker to function well and properly.
