being connected and the Tape In Level Control (18), so care must be taken in adjusting these levels so as to achieve proper balance in the final mix and to prevent overload distor- tion. The LED Output Metering Indicators (19, 20) can be used to maintain proper levels in the master mix. The L/R Normal LED Indicators (20) will light to indicate normal operating levels and you should always try to keep your levels within this range. Overload is indicated by the L/R Peak LED indicators (19). The Peak LEDs will light when the master mix is going into overload. It detects the peak level and will illuminate at 3dB before clipping to warn that the signal is approaching overload. You do not want the Peak LED to light except very intermittently during a take or a mix. If it does light persistently, reduce the master mix gain with the Master

Mix Gain Control (17).

c. Monitor Function and Operation

(26)HEADPHONES OUTPUT

(22)PHONES LEVEL CONTROL

(21)TAPE IN TO MASTER/TAPE TO HEADPHONES ONLY SWITCH

The SPM-835 allows you to monitor the Main Master Mix. The signal level is adjusted with the Phones Level control (22) and routed to the Headphones (26) output. The Phones Output (26) will feed headphones and is a 1/4” TRS jack, wired: tip = left signal, ring = right signal, sleeve = ground. (Note: Use only headphones with an impedance >50 Ohms or you may experience some distortion.) If desired, this output can also be connected instead to an amplifier and speakers for control room or stage monitoring. The Tape In To Master/Tape To Headphones Only Switch (21) can be set to the “up” position to route the signal input to the Tape In jacks (15) to the headphones for selective monitoring of the Tape In signal only.

d. Power Connection and Switches

(29)AC POWER IN SOCKET

(27)MAIN POWER SWITCH

(13)POWER ON LED INDICATOR

(30)FUSE HOLDER

(31)PHONO GROUND TERMINAL

Check the power source for the proper voltage (115VAC or 230VAC) noted below the Power In Socket (29). Once you have connected the AC power cord to the AC power source and the AC Power In Socket (29), switch on your mixer with the Power On switch (27). The Power “ON” LED (13) will light up. Allow 1 minute after powering up for the system to reach equilibrium before setting input gains and other levels. You can leave the SPM-835 on all the time. It is conservative- ly designed, so heat build up isn’t a problem even in 24-hour- a-day operation. There’s nothing that will burn out or get used up. Alternatively, you can just plug every unit in your total

system into a Nady power conditioner PCL-800/810/815 or a good quality power strip, for one-button turn-on.

If you are using a turntable in your setup it is a good idea to connect it’s ground to the Phono Ground Terminal (31) to avoid hum and/or possible shock.The SPM-835 is fused for your (and its own) protection. If a fuse blows, disconnect the AC cord, and replace the fuse with a 2.0A SLO-BLO (5x20mm 250V), available at electronics stores or your dealer (or a 1.0A SLO-BLO, 5x20mm 250V, if your SPM-835 is a 220V-240V unit). If the fuse blows continuously upon replacement, unplug the unit and refer to qualified personnel for servicing before further use.

(28) PHANTOM POWER SWITCH

(12) PHANTOM POWER ON LED INDICATOR

When using condenser mics, +48VDC can be switched globally on or off to the XLR mic inputs for all mono channels (also see MONO INPUT SECTION, MIC INPUTS). When this switch is in the “ON” position, the Phantom Power On LED Indicator (12) will light, and +48VDC will be provided between pins 2 and 3 of all the mono Mic input XLR connec- tors. If you don’t need phantom power, be sure to turn this switch to the “OFF” position.

[Note: It is safe to connect balanced dynamic mics or line level devices even if this switch is on, but connecting unbal- anced devices or devices whose transformers are center- grounded will cause hum or malfunctions. Shorting the +48VDC can also damage your mixer. Also, turn down the Master Mix control (17) to prevent possible sharp transient noise from damaging the speakers when turning the phantom power on or off.]

SPM-835 specifications

The Nady Systems SPM-835 is a versatile and reliable choice for professionals seeking high-performance wireless microphone technology. Designed for a wide range of applications, including live performances, public speaking, and broadcasting, the SPM-835 offers exceptional audio quality and robust features that cater to the needs of musicians, presenters, and other users.

One of the standout features of the SPM-835 is its frequency diversity technology. This innovation minimizes interference and ensures a stable signal, providing users with a clear and uninterrupted audio experience. The system operates in the UHF frequency band, which is known for its ability to cover longer distances while offering better resistance to interference compared to VHF systems. The SPM-835 is equipped with multiple channels, allowing users to select the clearest frequencies, making it suitable for environments with potential signal disruptions.

The microphone itself features a dynamic design that is ideal for vocals. This characteristic not only enhances the richness of the sound but also ensures that it effectively captures the nuances of the speaker's voice. The SPM-835's cardioid pickup pattern further enhances its performance by focusing on the sound source while minimizing background noise. This makes the microphone particularly effective in live settings where ambient sounds can compete with the intended audio.

Another significant advantage of the SPM-835 is its ergonomically designed handheld transmitter. This transmitter is lightweight and easy to handle, making it comfortable to use for extended periods. It also features a battery life indicator, allowing users to keep track of power levels and avoid unexpected downtime during performances.

The system includes a compact receiver that boasts a range of connection options for easy integration with existing sound gear. Users appreciate the simple setup process, with easy-to-read LED displays for monitoring audio levels and signal strength. Additionally, the SPM-835 incorporates a range of advanced wireless technologies, including auto-scan frequency selection, which automatically searches for the clearest available frequency to ensure optimal signal quality.

The Nady Systems SPM-835 is an ideal choice for those looking for a reliable and feature-rich wireless microphone system. Its combination of advanced technology, user-friendly design, and superior audio performance makes it a top pick among audio professionals and enthusiasts alike.
