电脑声音调节技巧平衡音量和音质电脑声音调节技巧：平衡音量和音质现代人在使用电脑时，经常需要调节音量和音质，以便获得更好的音乐、游戏和视频体验。

本文将介绍一些电脑声音调节的技巧，帮助用户平衡音量和音质，提升听觉享受。

1. 系统音量调节：操作系统通常提供音量调节功能，用户可以通过调节音量滑块或者快捷键进行操作。

要平衡音量和音质，首先确保系统音量适中，不过高或过低。

过高的音量可能会导致失真，而过低的音量则会降低听音乐、看电影等体验。

2. 音频驱动程序设置：音频驱动程序提供了更精确的音量和音质调节选项。

用户可以在控制面板中找到音频驱动程序，然后根据自己的需要进行调节。

具体的设置可能因不同的驱动程序而异，但通常包括音量增益、音频均衡器、DSP效果等选项。

通过微调这些设置，可以改善音质并提高音量效果。

3. 使用均衡器调节音频频谱：均衡器是调节音频频谱的重要工具。

通过调节不同频率的音量，在保持平衡的同时，可以突出特定频段的声音。

比如，如果你想突出低音，可以适当提高低音频段的音量。

不同音频播放软件和驱动程序提供的均衡器可能略有不同，用户可以根据自己的喜好进行微调。

4. 使用音效增强器提升音质：有些声卡或音频软件提供音效增强器的选项，可以通过增强音频细节、虚拟环绕音等功能，提升音质。

然而，要注意不要过度使用音效增强器，以免造成失真或变形。

5. 使用耳机音频解码器：如果你使用的是高端耳机，可以考虑购买并使用耳机音频解码器。

耳机解码器可以提供更高的音频采样率和比特率，从而提升音质。

此外，耳机解码器还通常具有均衡器和音效增强选项，用户可以根据自己的需求进行调整。

6. 避免音频压缩：音频文件经过压缩后，往往会损失一部分音质。

尽量选择无损音频格式，如FLAC、APE等，以获得更高的音质。

对于在线音乐和视频，选择高比特率的版本也有助于提升音质。

7. 消除电脑噪音：电脑在工作时会产生一些噪音，如电流声、风扇声等。

这些噪音会干扰音频的听感。

音频音域控制：Adobe Premiere Pro的均衡器和音效技巧Adobe Premiere Pro是一款功能强大的视频剪辑软件，除了视频处理功能外，它也提供了一系列优质的音频编辑工具。

其中，均衡器和音效技巧提供了音频音域控制的有效方式，让您能够为您的视频添加令人惊叹的音频效果。

首先，让我们来了解一下均衡器的基本知识。

均衡器是一款音频处理设备，能够通过增强或削弱不同频率范围内的声音，来改善音频的音质。

在Adobe Premiere Pro中，我们可以使用均衡器来调整音频中特定频段的音量。

在添加音频轨道后，您可以在效果面板中找到“均衡器”效果。

将均衡器拖动至音频轨道上，通过打开“效果控件”窗口，您将能够查看和调整均衡器的各个频段。

每个频段都有一个滑块，您可以将其向上或向下拖动来调整该频段的音量。

通过使用均衡器，您可以增强或削弱音频中的低音、中音和高音。

此外，Adobe Premiere Pro还提供了丰富的音效技巧，以进一步改进音频效果。

例如，您可以使用“回声”效果在音频中添加回音效果，使其听起来更加立体和空灵。

您可以通过调整回音强度和回音延迟来控制回声的效果。

另一个强大的音效技巧是“混响”。

混响可以模拟不同的房间或环境中的声音反射，为音频增加自然的环境感。

通过调整混响的参数，如混响时间和混响强度，您可以让音频听起来像是在一个小礼堂、大教堂或其他不同的环境中。

除了回声和混响之外，Adobe Premiere Pro还提供了许多其他音效技巧，如音频失真、音频延迟和音频扩展等。

这些技巧可以根据您的需求和创意来使用，以创建独特而令人惊叹的音频效果。

在调整音频的过程中，还有一些重要的事项需要注意。

首先，确保您的音频调整与视频内容相匹配。

音频效果应该与视频的情感和氛围保持一致，以提供更好的观影体验。

其次，谨慎使用音效技巧，过度使用可能会导致音频效果过于夸张或不自然。

最后，通过反复尝试不同的音频效果和设置，找到最适合您视频的音频效果。

The amplifier can be reset by turning the remote power off and then on again. If the amplifier shut down due to a thermal overload condition, please allow it to cool down before restarting. If the amplifier shut down becauseof an input overload or short circuit, be sure to repair these conditions before attempting to power up the amplifier again.Controls & FunctionsThe mounting position of your Amplifier will have a great effect on its ability to dissipate the heat generated during normal operation.Under normal conditions, the heatsink will dissipate sufficient heat to avoid thermal shutdown. However please do not install the amplifier in a wooden box or similar device as this will prevent heat dissipation into the atmosphere.Temperatures in car trunks have been measured as high as (155'F) in the summer time. since the thermal shut-down point for the amplifier is (158'F) it is easy to see that it must be mounted for maximum cooling capability. To achievemaximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a horizontal position.Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not often allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least1 inch of clearance (2.54 cm) above the Amplifier's fins for ventilation.A. Select a suitable location that is convenient for mounting, is accessible for wiring. And has ample room for air circulation and cooling.B. Use the amplifier as a template to mark the mounting holes.

The Eris XT studio monitors provide a choice of three line-level input types: balanced XLR, balanced ¼” TRS, and unbalanced RCA. Do not connect more than one source to your Eris XT studio monitors simultaneously. Power User Tip: Whenever possible, it is recommended that you utilized the balanced line-level inputs on your Eris XT studio monitors. Balanced cables and connections are resistant to induced noise from radio frequencies and electromagnetic interference (RMI and EMI). If your audio source has only unbalanced connections (either ¼” TS or RCA), it isPower Switch. This is the On/Off switch for your Eris XT studio monitor. When yourEris XT studio monitor is powered On, the blue LED on the front panel will illuminate.AC Select Switch. The input-power voltage is set at the factory to correspond withthe country to which the Eris XT studio monitor was shipped. Use this switch only ifPower User Tip: The High control on the Eris XT studio monitors is a high-shelf EQ and raises or lowers all frequencies above 10 kHz. This EQ is much like the treble control on a car stereo and likewise can make big changes to the sound very quickly. If you find yourPower User Tip: If you are using a subwoofer that doesn’t feature a variable low pass filter, like the PreSonus Temblor T10 provides, you will use this control to set the crossover point for your 2.1 system. For information on configuring a 2.1 system in the studio, please visit /Learn/Technical-Articles.Cuts the level of all frequencies below 800 Hz by either -4 dB or -2The closer your studio monitors are to a wall or a corner, the more thefrequency response and help to mitigate a compact mix position. For more informationon studio monitor placement, please review Section 3.1.2.2 Hookup DiagramsBasic Setup2.2.12.2.2 Advanced Setup with Monitor Controller and Speaker SwitchingSceptre S6Eris E5XT3 Application Guide3.1 Monitor Placement and Acoustic Space Settings Eris XT-Series E5XT / E8XTOwner’s Manual33.1 Monitor Placement and Acoustic Space SettingsBefore placing your studio monitors in your mixing environment, position yourdesk or monitor stands so that your speakers will be at least 8 to 12 inchesaway from walls and corners. This will be adequate to prevent sound wavesfrom hitting the wall and reflecting back to you, causing phase cancellationand other potentially harmful acoustic interactions. This might not always bepossible, and there are some ways to mitigate cramped mixing spaces.When a monitor is placed close to a wall, or in a corner, the low frequenciestend to be emphasized more than if the monitor is some distance away fromany room boundary. Commonly referred to as “boundary bass boost,” it ismost pronounced if the monitor is in a corner and less pronounced, but stillpresent, if the monitor is near one wall. While an increased bass responsemay be desirable in a listening environment, for studio mixing this cancause mixing to sound too bright when played on consumer stereo systemsbecause the audio engineer will instinctively reduce the bass content inthe mix to counterbalance for what they are hearing in the studio.To compensate for this phenomenon, every PreSonus studiomonitor is equipped with an Acoustic Space control that cutsall frequencies below 800 Hz by a specified amount:•If your Eris XT studio monitors are close to the corners ofthe room, start by setting the Acoustic Space switch to -4dB. This will provide the most bass attenuation.•When Eris XT studio monitors are placed closer to theback wall, set the Acoustic space switch to -2 dB.•If your mix environment affords enough space for your studio monitorsto be placed away from the room’s boundaries, leave the AcousticSpace switch at 0 dB as no bass attenuation should be necessary.3 Application Guide3.1 Monitor Placement and Acoustic Space Settings Eris XT-Series E5XT / E8XTOwner’s Manualthis will provide a more balanced listening position. Place your speakers so that they are the same distance from the sides of the room. That is, if yourleft speaker is six feet from the wall to the left and two feet from the wall behind, your right speaker should be six feet from the wall to the right and two feet from the wall behind. By centering your mix position, your monitor system will provide more reliable low-frequency intelligibility. In a rectangular room, it is best to set up along one of the long walls, especially in a smaller room. This will minimize problems caused by side wall reflections.Just like it’s not a good idea to set up your mix position in a corner, it’s not a good idea to create a corner with your mix position. Make sure the distance from the speaker to the wall behind it is different than the distance fromthe side wall closest to it. For example, if your left speaker is one foot from the wall to its left, it shouldn’t also be one foot from the wall behind it.The Eris XT’s focused EBM waveguide design ensures wider horizontal coverage with a tight vertical dispersion that helps to limit early reflections from your desk or console. Unlike other Eris monitors thatcan be placed horizontally or vertically, this design requires that theEris XT monitors always be placed in their vertical orientation.Whenever people talk about listening to speaker systems, theytalk about the “sweet spot.” As mentioned earlier, this is the middleposition between the two sides of a stereo system, where the speakers overlap, and it is where the stereo image will be the best.Creating the sweet spot is relatively easy. Simply angle, or “toe-in,” eachspeaker so that the tweeters form an equilateral triangle with yourhead—that is, the speakers are the same distance from each other asthey are from you. The monitors should be angled, or “toed in,” so thatthey are each directed to an ear, rather than pointed straight ahead.The main purpose of speaker calibration is to ensure that a specific metered audio level in your DAW or on your mixer equals a predetermined SPL in your studio environment. Depending upon the method and reference levels used during calibration, proper calibration can help reduce unwanted noise, minimize the risk of damage to your studio monitors and to your ears, maximize the reference capabilities of different speaker types, and ensure you hear the audio as accurately as possible. When calibrating reference monitors in a studio, the acoustic level orsound pressure level (SPL) should be measured from the mix position atseated ear height. There are an assortment of great SPL metering appson the market for smartphones, and many are free! You can also findaccurate SPL meters at your favorite local electronics-supply store.The SPL meter should be held at arm’s length, with the microphone pointed atthe center point between the left and right speakers (where your head will be), angled at 45 degrees to ensure an accurate reading. If your SPL meter is also your cell phone, make sure your finger or cell phone case isn’t covering the mic!You should calibrate the right and left monitors independently to ensure that both monitors are set to the same acoustic level. This will ensure that your stereo mixes are balanced and will translate well across different speaker systems.The goal of this Standard Reference Calibration is to ensure that when the output meters in your DAW or mixer register 0 dB, the SPL at your mix position is 85 dB. 1. Connect the main outputs of your audio source to your studio monitors.dB instead. The important thing is that both speakers are set to the same SPL level, not the level itself.4 Resourc es4.1 Technical Specifications Eris XT-Series E5XT / E8XTOwner’s Manual44.1 Technical SpecificationsInputs 1- Balanced XLR1- Balanced ¼” TRS1- Unbalanced RCA Performance E5XT E8XT Frequency Response 48 Hz to 20 kHz 35 Hz to 20 kHz Crossover Frequency 3 kHz 2.2 kHz LF Amplifier Power 45W 75W HF Amplifier Power 35W 65W Peak SPL (@ 1 meter) 102 dB 105 dB LF Driver 5.25” 8”HF Driver 1” Silk Dome 1.25”User ControlsVolume Range A-Type TaperMF Control -6 to +6 dBHF Control -6 to +6 dBLow Cut Flat, 80 Hz, 100 HzAcoustic Space Flat, -2 dB, -4 dBProtection RF interferenceOutput-current limitingO ver-temperatureTurn-on/off transientSubsonic filterExternal mains fusePower 100-120V ~50/60 Hz or 220-240V ~50/60 Hz Cabinet Vinyl-laminated, medium-density fiberboard PhysicalWidth 8” (203 mm) 9.75” (248 mm) Depth 9” (229 mm) 11.5” (292 mm) Height 11” (279 mm) 16” (406 mm) Weight 11 lbs (5 kg) 23 lbs (10.4 kg)4 Resourc es4.2 Troubleshooting Eris XT-Series E5XT / E8XTOwner’s Manual4.2 TroubleshootingNo Power. First ensure that your Eris XT studio monitor is plugged in. Ifit’s connected to a power conditioner, verify that the power conditioneris turned on and functioning. If problem still exists, disconnect the powercable from your studio monitor and check the fuse on the back panel.The fuse housing is located directly beneath the IEC power cable connection. Ablown fuse may look black on the inside or the wire inside might appear broken.A very black fuse is a sign that something may have shorted out. Try replacingthe fuse with a new one. The E5XT uses a T1L fuse. The Eris E8XT uses a T2Lfuse. If the fuse blows again, you will need to contact PreSonus for a repair.No audio. If your Eris XT studio monitor appears to power on but youhear no sound when playing audio from your audio source (the lights areon but nobody’s home), first make sure that the cable connecting youraudio source to the monitor is working correctly. Also, verify that theInput Gain control is set to provide enough amplitude for the signal.Hum. Usually, hum is caused by a ground loop. Verify that all audio equipment isconnected to the same power source. If you are not using a power conditioner,we highly recommend that you add one. Not only will this help to minimizehum, it will better protect your equipment from power surges, brownouts, etc.Use balanced cables whenever possible. If your audio device does not offera balanced output, you can connect it to a direct box, which will provide aground-lift switch and a balanced output. Finally, make sure that your audiocables are not run near power cables, and use cables that are the appropriatelength for your application. Using cables that are too long not only increasesthe risk of noise, it increases the likelihood that the cables are coiled, which willessentially create an antenna that picks up all kinds of audio interference.© 2019 PreSonus Audio Electronics, Inc.
