HDCP (High-bandwidth Digital Content Protection)**
HDCP is a copy protection protocol used to prevent the unauthorized copying of digital audio and video content. HDMI inputs and outputs on receivers will support specific versions of HDCP. Most modern devices require HDCP 2.2 or HDCP 2.3 for 4K UHD content. If your source device (e.g., a UHD Blu-ray player) and your display (TV/projector) require a specific HDCP version, your receiver must also support it on the relevant HDMI ports. Receivers with HDMI 2.1 typically support HDCP 2.3 across all their ports.
Specific HDMI Input Features
Some HDMI inputs on receivers might have specialized features:
* **ARC/eARC:** As mentioned, these allow audio to be sent from your TV back to the receiver over the same HDMI cable that carries video to the TV. eARC, found on HDMI 2.1, offers much higher bandwidth than ARC, enabling it to carry lossless audio formats. If you plan to use your TV’s smart apps and want to send that audio to your receiver’s speaker system, ARC or eARC is essential.
* **CEC (Consumer Electronics Control):** CEC allows devices connected via HDMI to control each other. For example, you can use your TV remote to turn on/off your Blu-ray player or adjust the receiver’s volume. Different manufacturers have their own branding for CEC (e.g., Anynet+ for Samsung, SimpLink for LG, BRAVIA Sync for Sony). For CEC to work effectively, both the receiver and the connected devices must support it, and it needs to be enabled in the settings of all devices.
Connecting Your Devices: A Practical Overview
With your receiver equipped with ample HDMI inputs, connecting your home theater components becomes straightforward.
The Standard Setup
1. **Connect Sources to Receiver:** Use an HDMI cable to connect each of your audio-video sources (Blu-ray player, game console, streaming device, etc.) to a dedicated HDMI input port on your AV receiver.
2. **Connect Receiver to Display:** Use another HDMI cable to connect the receiver’s HDMI output port (usually labeled “HDMI Out” or “Monitor Out”) to the HDMI input port on your TV or projector.
3. **Connect Speakers to Receiver:** Connect your surround sound or stereo speakers to the appropriate speaker terminals on the back of the receiver using speaker wire.
Leveraging HDMI Capabilities
Once connected, you’ll typically navigate your receiver’s on-screen display (OSD) or a dedicated mobile app to select the desired HDMI input. The receiver will then automatically process the audio and video signals and pass them to your display and speakers.
For features like ARC/eARC, you’ll need to ensure the HDMI cable is connected to the correct ARC/eARC-compatible ports on both the receiver and the TV, and that the feature is enabled in the settings of both devices.

Do all receivers have HDMI inputs?
No, not all receivers necessarily have HDMI inputs. While modern AV receivers almost universally feature HDMI connectivity, older models or entry-level audio systems might rely on older analog or digital audio/video connection standards such as component, composite, optical, or coaxial. When purchasing a receiver, it’s crucial to check its specifications to confirm the presence and number of HDMI ports.
The prevalence of HDMI in receivers is directly tied to the evolution of audio and video technologies. HDMI provides a single cable solution for transmitting both high-definition video and multi-channel digital audio, significantly simplifying setup and improving signal quality compared to older connection methods. Therefore, any receiver designed for contemporary home theater systems will almost certainly include multiple HDMI inputs.
What are the benefits of using HDMI inputs on a receiver?
The primary benefit of using HDMI inputs on a receiver is the ability to transmit uncompressed digital audio and high-definition video signals through a single cable. This streamlined connection eliminates the need for multiple cables for separate audio and video signals, reducing clutter and potential for connection errors. Furthermore, HDMI supports advanced audio formats like Dolby Atmos and DTS:X, providing a more immersive surround sound experience.
Beyond convenience and superior audio/video quality, HDMI inputs on receivers enable features like HDMI ARC (Audio Return Channel) and eARC (Enhanced Audio Return Channel). These functionalities allow audio to be sent from a TV back to the receiver via the same HDMI cable used for video, simplifying audio setup for smart TV apps or broadcast content. eARC, in particular, offers higher bandwidth for uncompressed, object-based audio formats.
How many HDMI inputs do most modern receivers have?
Most modern AV receivers typically come equipped with a generous number of HDMI inputs, often ranging from four to eight on entry-level to mid-range models. Higher-end receivers, designed for more complex home theater setups, can feature ten or even more HDMI inputs, catering to a wide array of source devices like Blu-ray players, gaming consoles, streaming boxes, and cable/satellite receivers.
The exact number of HDMI inputs can vary depending on the receiver’s target market and price point. It’s important to consider your current and future needs when choosing a receiver. If you anticipate connecting numerous devices, opting for a receiver with ample HDMI inputs will prevent the need for external HDMI switches down the line and ensure a cleaner, more integrated system.
Can I use HDMI inputs for audio-only devices?
While HDMI is primarily designed for combined audio and video transmission, it can indeed be used for audio-only devices if they output audio via HDMI. However, this is less common for dedicated audio-only sources. Typically, audio signals from devices like CD players or turntables are handled through analog or digital optical/coaxial connections, respectively.
In scenarios where an audio device, such as a network streamer or a high-resolution digital audio player, has an HDMI output that can be configured to output audio only (often referred to as “audio out” or similar), it can be connected to an HDMI input on a receiver. The receiver will then process the audio signal and ignore any potential video stream, providing a clean audio path.
What is the difference between HDMI input and HDMI output on a receiver?
An HDMI input on a receiver is a port designed to receive audio and video signals from an external source device, such as a Blu-ray player or gaming console. These inputs allow the receiver to process and route these signals to the connected display (TV or projector) and the speaker system, respectively.
An HDMI output, on the other hand, is designed to send processed audio and video signals from the receiver to another device, most commonly a television or projector. Most AV receivers feature at least one HDMI output, often labeled “HDMI Out (ARC)” or similar, which serves as the primary connection to your display. Some receivers may have multiple HDMI outputs to support simultaneous connections to different displays.
Can I connect older devices that don’t have HDMI to a receiver with HDMI inputs?
Yes, you can connect older devices that lack HDMI to a receiver with HDMI inputs, but you’ll typically need adapters or converters. For example, if your older device uses component video and analog audio connections, you’ll need a component-to-HDMI converter to bridge the gap. These converters take the analog signals and convert them into a digital HDMI signal that the receiver can understand.
The quality of the conversion can vary, and some converters may introduce a slight degradation in signal quality or introduce latency. It’s important to research and choose a reputable converter for the best results. Alternatively, if your receiver has legacy analog or digital audio inputs (like composite, S-Video, optical, or coaxial), you might be able to connect older devices directly using those ports for audio, provided you use a separate video connection to your display.
What is HDMI ARC/eARC and how does it relate to receiver HDMI inputs?
HDMI ARC (Audio Return Channel) and its enhanced version, eARC (Enhanced Audio Return Channel), are features that allow audio to be sent “upstream” from a TV back to an AV receiver over the same HDMI cable that carries video to the TV. This eliminates the need for a separate audio cable, simplifying connections, especially for smart TV apps or over-the-air broadcasts viewed directly on the TV.
When a receiver has an HDMI input that supports ARC/eARC, it means that a specific HDMI input port on the receiver is designated to receive both incoming video/audio signals from a source and outgoing audio signals from the TV. The TV also needs to have an ARC/eARC enabled HDMI port, and both devices must have ARC/eARC enabled in their settings for the feature to work. eARC, being a newer standard, offers significantly higher bandwidth, supporting uncompressed, object-based audio formats like Dolby Atmos and DTS:X.
