12V Out Jack

The Trigger Out jack lets you loop or “daisy-chain” the incoming trigger voltage to an additional Model 5125 or other component.

Note: The Model 5125 trigger circuit draws a negligible 15 mA from the controller. The total load on your controller’s trigger output(s) is the sum of the trigger current drawn by each of the com- ponents you’ve looped together. Controllers can typically supply 150 mA at their trigger outputs.

Audio Trigger Sens (Sensitivity) Knob

The Auto Turn On Audio Sensitivity knob adjusts the incoming audio level or the “threshold” required to turn on the Model 5125. Its 12 o’clock position will be suitable in most cases. To increase sensitivity for response to lower level audio signals, turn the knob counter-clockwise toward +.Turn the knob clockwise toward - to decrease its sensitivity. This will prevent spurious noise and switching transients in your system from false-triggering the Model 5125.

Note: Plugging in the 5125’s AC cord for the first time will usually create an internal power surge that “false triggers” its Audio auto turn on, even if there’s no audio signal at its input jacks, and it will remain on for 10-15 minutes after you switch it off. This is normal.

Ground Switch

Ground is the normal position for this switch. If you hear background

hum in the speakers connected to the Model 5125, try setting the Ground Lift Switch to its Lift position. The Ground Switch disconnects or “lifts” the audio circuit ground from the chassis ground. This often helps to eliminate audible hum that results from ground loops. Ground loops are multiple ground paths such as the metal-to-metal contact

with the panels or chassis of other components combined with the

ground connections of the audio cables or even the ground wires of the various AC cords.

AC Power Connections and AC Grounding

If possible, plug your Model 5125 into the same AC outlet that your accompanying audio com- ponents (especially the system controller) are plugged into. The ground potential between dif- ferent AC outlets may be higher or lower, resulting in audible hum.

5125 specifications

The Parasound 5125 is a highly regarded power amplifier designed for both critical listening and home theater applications. Renowned for its performance, the Parasound 5125 combines advanced technologies and user-friendly features, making it an attractive choice for audiophiles and casual listeners alike.

One of the standout attributes of the Parasound 5125 is its robust power output. It delivers 125 watts per channel into 8 ohms and 200 watts into 4 ohms, providing ample power for driving a wide variety of speakers, from bookshelf models to larger floor-standing designs. This level of power ensures that the amplifier can comfortably handle dynamic peaks found in music and film soundtracks, producing clear and impactful audio without distortion.

The Parasound 5125 incorporates the renowned patented "Halo" technology, which is designed to minimize distortion while maximizing sound quality. This technology includes a high-current design that allows the amplifier to maintain a tight grip on the speaker, thus delivering precise control over transients. This results in greater sonic detail, lifelike imaging, and an overall more engaging listening experience.

Additionally, the amplifier features a fully balanced input design that helps to reduce noise interference, delivering a cleaner and more accurate signal to the output stage. This balanced input is complemented by gold-plated RCA inputs, offering versatility in connectivity options. The robust construction of the Parasound 5125 includes a heavy-duty chassis, which helps in minimizing vibrations that can negatively impact audio performance.

Another notable characteristic is the efficient thermal management system in the Parasound 5125. It utilizes a low-noise fan that activates only when necessary, maintaining optimal operating temperatures while remaining discreet in terms of noise production. This feature allows the amplifier to operate continuously without overheating, ensuring reliability during extended listening sessions.

In terms of aesthetics, the Parasound 5125 boasts a sleek and modern design, characterized by its elegant front panel and blue LED indicators. It's not only built for performance but also harmonizes well with contemporary home theater setups.

Overall, the Parasound 5125 stands out for its combination of powerful output, innovative technology, and solid build quality. It is designed to deliver exceptional audio performance, making it an ideal choice for anyone looking to enhance their audio system with a reliable and high-performing power amplifier.
