8.BALANCED INPUT CONNECTORS (1/4" TRS & XLR) These balanced 1/4” (6.3mm) TRS (Tip/Ring/Sleeve) phone jacks and balanced XLR jacks are designed to accept line level balanced or unbalanced signals for each channel. They are wired Tip/Pin 2 = (+), Ring/Pin 3 = (-), and Sleeve/Pin 1 = Ground. Balanced input signals are recommended, as they are

less prone to AC hum. For long cable runs, a source of less than 600Ω output impedance is needed to avoid signal loss. For

short cable runs an unbalanced signal input should be suitable.

Since the TRS phone jacks and XLR jacks are wired together internally for each channel, you can parallel these jacks with another amplifier by connecting either the 1/4" jack or the XLR jack to the input jack of another amplifier. You can also parallel the inputs of two channels together using this same technique.

9. LOW PASS FREQUENCY CONTROL

This control adjusts the roll-off frequency point of the internal low pass filter from 50Hz to 250Hz. Adjust this control, with music playing, to find the frequency setting that delivers the best punch from your subwoofers. The Filter/Source Switch

(10)must set to ON to use this function.

10. FILTER / SOURCE SWITCH

This switch enables or disables the internal low pass filter. When the switch is set to ON, the internal low pass filter is enabled, the Subwoofer inputs should remain unused, and the input signals of channel 1 and 2 are used as the source for the subwoofer. The Ch 1 and 2 signals are combined and sent through the crossover and on to the Subwoofer output.

When the switch is set to OFF, the internal crossover is disabled and the Subwoofer input is used as the source. This allows the use of an external active crossover or using the Sub channel to pass full-range signals for monitor feeds or sound reinforcement.

11. LOW CUT FILTER SWITCH

This switch enables/disables the low cut filter for the Subwoofer output. The filter has a fixed roll-off frequency at 30Hz with 12dB/octave of cut. This can tighten up the sound while reducing muddy bass and stage rumble. This filter is only active when the Filter/Source Switch (10) enabled.

12. OUTPUT CONNECTORS

These binding post (banana) connectors can accommodate banana plugs, MDP modular dual plugs, or they can be unscrewed and used for simple binding post connections. Make sure all connections are tidy and there are no loose wires sticking out that could short the outputs. Connections are as depicted on the rear panel and in the following SPEAKER CONNECTIONS section on page 7 of this manual.

[Caution: Make sure that the speaker, speaker connectors, and wiring can handle the rated output power to avoid damage. Speaker power ratings (in RMS) should always exceed amplifier power ratings. Note that prolonged use at levels in excess of clipping can possibly drive the amplifier into thermal runaway and damage the internal amplifier and speaker, so care must be taken not to overload the amplifier. Never use less than 4Ω total impedance for any channel, as this also can cause the amplifier to overheat and create thermal runaway.]

13. FANS

The four variable-speed fans adjust speed automatically to maintain the proper internal operating temperature. Never block the air vents on the front, back, and side panels of the amplifier to allow proper ventilation.

14. POWER CONNECTOR

The cord connector is used to connect the 115VAC power source to your power amplifier.

[Caution: Never remove the center grounding pin as this can cause a serious safety hazard and will immediately void your warranty.]

15. FUSE

The fuse holder contains a 3AG fast blow fuse. If this fuse continuously blows, shut off the unit and have it serviced by the Nady Service Department.

3WA1700 specifications

Nady Systems has built a reputation in the wireless audio technology arena, and one of its standout offerings is the 3WA1700 wireless microphone system. The 3WA1700 is designed to cater to a variety of performance settings, including live sound venues, houses of worship, and corporate events. Its robust features, advanced technology, and user-friendly characteristics make it a compelling choice for both professionals and amateurs alike.

At the heart of the 3WA1700 system is its reliable UHF (Ultra High Frequency) wireless technology. Operating in the 1700 MHz frequency band, this system minimizes interference and offers superior sound quality, ensuring that users can perform without the interruptions commonly found in other wireless systems. This is particularly advantageous in crowded areas with multiple devices vying for frequency space, as the 3WA1700 maintains a stable signal even in challenging environments.

The 3WA1700 also employs a diversity reception system that enhances signal reliability and minimizes dropouts. This technology utilizes two antennas to receive incoming signals, automatically switching between them to ensure a consistent connection. This feature is particularly valuable for performers who need the freedom to move around the stage without fear of audio loss.

Another significant aspect of the 3WA1700 is its user-friendly design. The system features a clear LCD display on the receiver that provides vital information such as battery life, signal strength, and frequency settings. This intuitive interface allows users to make adjustments quickly and efficiently, making it easy to transition between different audio settings as needed.

In terms of versatility, the 3WA1700 comes equipped with multiple microphone options, including handheld, lavalier, and headworn microphones. This diversity allows users to select the microphone type that best suits their performance needs. The handheld microphone is particularly noted for its durability and high-quality capsule, which captures vocals with clarity and precision.

Furthermore, the 3WA1700 supports a substantial operating range, providing solid performance up to 300 feet, allowing performers the freedom to engage with their audience without being tethered to a fixed position. The long battery life ensures extended use, enabling users to focus on their performance without frequent interruptions for battery changes.

In conclusion, the Nady Systems 3WA1700 wireless microphone system is an impressive amalgamation of cutting-edge technology, user-centered design, and high-quality audio performance. Its frequency agility, diversity reception, and multiple microphone options make it a top choice for anyone looking to elevate their audio experience in live settings.
