- Follow Instructions: All operating and use instructions should be followed.
- Water and Moisture: The appliance should not be used near water-for example, near a bathtub, washbowl, kitchen sink, laundry tub, swimming pool, or a wet basement.
- Ventilation: The appliance should be situated so that its location or position does not interfere with its proper ventilation. For example, the appliance should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings: or placed in a built-in installation, such as a bookcase or cabinet that may impede the the flow of air through the ventilation openings.
- Heat: The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.
- Power Sources: The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance.
- Grounding or Polarization: Precaution should be taken to insure that the grounding or polarization means of an appliance are not defeated.
- Power-Cord Protection: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point at which they exit from the appliance.
- Cleaning: The appliance should be cleaned only as recommended by the manufacturer.
- Power Lines: An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.
- Non-use Periods: The power cord of the appliance should be unplugged from the outlet when the appliance is to be left unused for a long period of time.
- Object and Liquid Entry: Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.
- Carts and Stands: If the appliance is used with a cart or stand, the cart or stand should be a type recommended by the manufacturer. An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces cause the appliance and cart combination to overturn.
- Mounting: The appliance should be mounted only as recommended by the manufacturer.
- Damage Requiring Service: The appliance should be serviced by qualified service personnel when:
- The power-supply cord or plug has been damaged.
- Objects have fallen into, or liquid has been spilled into the appliance enclosure.
- The appliance has been exposed to rain.
- The appliance has been dropped, or the enclosure damaged.
- The appliance does not appear to operate normally or exhibits a marked change in performance.
-  Servicing: The user should not attempt to service the appliance beyond that described in the user’s operating instructions. All other servicing should be referred to qualified personnel.
- Overloading: Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.
- Replacement Parts: When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
- Safety Check: Upon completion of any service or repairs to this appliance, ask the service technician to perform safety checks to determine that the appliance is in proper operating condition.

FAQs Pyle PHA40 4-Channel Stereo Headphone Amplifier
A stereo headphone amplifier is what?
Talk in Articles. A low-powered audio amplifier known as a headphone amplifier is specifically made to drive headphones worn on or in the ears, as opposed to loudspeakers housed in speaker enclosures.
Does an amplifier enhance the sound quality of headphones?
While headphone amplifiers won’t enhance the clarity or accuracy of your headphones, they will give them the power they need to create a sound that is more in line with the experience for which they were intended.
Do high-end headphones require an amplifier?
Most in-ear and earbud headphones are quite effective and are less likely to greatly benefit from an amplifier. However, using an amp will make many larger over-ear headphones sound crisper and better.
What is a stereo amplifier’s benefit?
All instruments could be panned so that the majority of each signal came from a single speaker by mixing in stereo. Less interference between the left and right signals and fewer issues brought on by speaker phase issues would result.
What factors determine audio quality?
If the sample rate and bit depth are also high, a high bit rate generally equates to high-quality audio. In a broad sense, more information equates to higher sound quality. The bitrate for audio CDs is constant at 1,411 kilobits per second (Kbps).
Are 32-ohm headphones amplified?
Low impedance (8-32 ohm), sensitive (100 dB+), and often compatible headphones will work well with a portable source (like a phone) without much benefit from a separate.
Do amplifiers make the noise worse?
One of the most fundamental electrical components in every electronic system are amplifier. In addition to boosting the signal, amplifiers also inject a little amount of their own noise.
Amplifiers do they lessen noise?
Any electronic amplifier will amplify the signal and any noise that is present at the input while also adding some noise of its own. By using unique components, operating points, and circuit topologies, LNAs are created to reduce this extra noise.
Are 60-ohm headphones amplified?
For the optimum sound quality, an amplifier should be used with any set of headphones with an impedance rating of 50 ohms or above.
What kind of headphone amplifier do I need?
For a number of reasons, pairing a headphone with at least 10 times the impedance of the amplifier in use is the best way to determine an impedance-based pairing. For instance, a 30 ohm amplifier and a 300 ohm headphone might work nicely together.
