FRONT & REAR CONNECTIONS

10. L/R CHANNEL OUTPUT CONNECTORS

Connections are as depicted on the rear panel and in the follow- ing CONNECTIONS section on page 7 of this manual.

11.BALANCED INPUT CONNECTORS (1/4" TRS & XLR) These 1/4" (6.3mm) TRS (Tip/Ring/Sleeve) phone jacks and XLR jacks are compatible with balanced inputs and are wired as Tip/ Pin 3, Ring/Pin 2, and Sleeve/Pin 1 = Ground. Normal maximum input level at clipping is .500V RMS. Input impedance is 50K Ohms. Since the TRS phone jacks and XLR jacks are wired internally in parallel, you can parallel this unit with another amplifier by using either the LINE 1/4" jack or the XLR jack (depending on which you’re using to input your signal) to output the signal to the input jack of the other amplifier.

The 1/4" TRS phone jacks can also be used for unbalanced inputs. For TRS phone plugs, simply connect the unused side of the balanced input to ground. For 1/4" TS phone plugs, no change is necessary for compatibility with this input. Balanced input signals are recommended as they are less prone to AC hum. For long cable runs a source of less than 600 ohms output impedance is needed to avoid signal loss. For short cable runs an unbalanced signal input should be suitable.

For stereo (two-channel) operation, use the inputs for both CH-A and CH-B; for parallel or bridged mono operation, use only CH-A input. (See MODE SELECTOR SWITCHES below for more explanation.)

12.MODE SELECTOR SWITCH

The XA-300 amplifier offer 3 modes of operation: PARALLEL, STEREO & BRIDGED. Slide the switch to one of the three positions for you application.

•PARALLEL (MONO) INPUT - This mode allows both chan- nels to operate in parallel with the same signal and without requiring a Y-cord. In this mode the inputs for both channels are

internally connected, so that you only need to feed a signal into one of the channels. This still allows independent control of each channel. (Note: Do not select this “Parallel” mode when feeding the amplifier 2 separate signals.)

(Note: Do not use both unbalanced and balanced cables in the same set-up as that can unbalance all the connections when daisy-chaining, resulting in hum.)

•STEREO INPUT - This is the most common mode generally used, and allows independent control of 2 separate signals such as stereo playback, main and monitor live mixes, and bi- amp operation (highs in one channel and lows in the other).

•BRIDGED MONO - This mode combines the power of both channels to drive a single speaker. In this mode the amp produces 4 times the peak power and 3 times the sustained power into a 4 or 8 ohm speaker than each channel can deliver separately in stereo or parallel mode.

(CAUTION: In this mode the amplifier can deliver high power into a speaker. Make sure that the speaker, connectors and wiring can handle this output. Note that for prolonged overdriven outputs into a 4 ohm speaker the breaker may trip, so care must be taken not to overload the amplifier in such operation.)

Connect the input signal to CH-A input for bridged mono operation.

13.FANS

The variable speed fans switch between idle speed and high speed automatically to maintain the proper internal operating temperature.

INSTALLATION

To ensure years of enjoyment from your NADY AUDIO XA-300 amplifier, please read and understand this manual thoroughly before using the unit.

INSPECTION

Your XA -300 amplifier was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit.

(Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.)

RACK MOUNTING

The XA-300 amplifier is designed for standard 19" rack mounting as well as “stack” mounting without a cabinet. Use 4 screws and washers for mounting to the front rack rails. It is also a good idea to support the amps also in the rear, especially for mobile use where the amps will be subjected to shocks.

AMPLIFIER COOLING

Also pay close attention to the cooling requirements. Never block the air vents in the back side and front of the amplifier if the load seen by amplifier is less than 4 ohms and the amplifier is being run at high output levels. For best results, in such high output power applications you should augment the amplifier’s air flow with a rack cooling system.

XA-300 specifications

Nady Systems XA-300 is a versatile and innovative piece of audio equipment designed for both professional and amateur users. This device is widely recognized for its exceptional sound quality, reliability, and a range of features that cater to various audio needs.

One of the standout features of the XA-300 is its wireless technology, which utilizes UHF frequencies to deliver clear and uninterrupted audio signals. This ensures minimal interference, making it ideal for applications such as live performances, presentations, and public speaking events. With a range of up to 300 feet, performers can move freely without the constraints of cables.

The XA-300 comes equipped with a dual-channel receiver, allowing users to operate two microphones simultaneously. This feature is particularly beneficial for collaborative performances, interviews, or any scenario where multiple speakers need to be heard clearly. Each channel can be independently adjusted for volume, enabling precise control over the audio output.

In terms of microphone options, the XA-300 supports both handheld and lavalier microphones. The handheld microphone is designed for ease of use during performances, while the lavalier option provides discreet audio capture for presenters and speakers who prefer a more subtle approach. Both types of microphones feature Nady's advanced audio technology, which enhances clarity and reduces background noise.

Another technological highlight of the XA-300 is its built-in DSP (Digital Signal Processing). This technology enables users to customize audio settings, applying effects such as reverb and echo, thereby enhancing the overall sound experience. This feature is invaluable for musicians and performers who want to add depth and professionalism to their audio output.

The XA-300 also boasts rugged construction, making it suitable for both indoor and outdoor use. Its durable casing ensures that the equipment can withstand the rigors of touring and travel. Additionally, the device is designed with user-friendliness in mind, featuring an intuitive interface that allows for quick and easy setup.

The device operates on AA batteries, providing long-lasting power, and can also be connected to external power sources for extended use. Furthermore, the XA-300 includes LED indicators for battery life and signal strength, ensuring that users are always aware of their equipment's status.

In summary, the Nady Systems XA-300 is a powerful and flexible audio solution that combines advanced technology with practical features. Its wireless capabilities, dual-channel operation, and durable design make it a preferred choice for musicians, speakers, and audio professionals alike. Whether used in a small venue or a large auditorium, the XA-300 delivers exceptional performance and reliability.
