Frequently Asked Questions - SF-NP35E RDL

How do I connect the receiver to my TV?

Use an HDMI cable to connect the HDMI OUT (ARC) port on the receiver to an HDMI input on your TV. Ensure ARC is enabled on both devices.

Can I use the receiver without a remote?

Yes, basic functions can be accessed via front panel buttons. However, the remote is recommended for full control.

What is the maximum power output per channel?

The receiver delivers 100W per channel at 8 ohms with 2 channels driven.

How do I reset the receiver to factory settings?

Press and hold the Power button for 10 seconds while the unit is on. The display will show 'RESET' and then restart.

Why is there no sound from my speakers?

Check that speakers are correctly connected to the speaker terminals, the input source is selected, and the volume is not muted. Also verify the source device is outputting audio.

Can I connect a turntable to this receiver?

Yes, if your turntable has a built-in preamp, connect it to any RCA audio input. If not, you will need an external phono preamp.

Does the receiver support Bluetooth?

No, the SF-NP35E does not have built-in Bluetooth. You can add a Bluetooth adapter to one of the audio inputs.

How do I update the firmware?

This receiver does not support firmware updates. To address issues, contact RDL support.

What should I do if the receiver overheats?

Ensure proper ventilation around the unit. Do not block the cooling vents. If overheating persists, turn off the receiver and let it cool for 30 minutes before resuming use.

Can I use the receiver with 2-ohm speakers?

No, the receiver is designed for speakers with an impedance of 4 to 16 ohms. Using 2-ohm speakers may cause damage.

The SysFlex® series is a family of A/V modules providing complex interface solutions at the click of a connector. SysFlex modules provide connectorized interface between data networks and analog and digital audio devices, networked and conventional amplifiers and other application-specific solutions. In RDL's tradition of versatility, SysFlex modules can be used right where they are needed: Rack-mounted, Surface-mounted, or unmounted. They are light-weight, compact and easy to install with simple, straightforward switch settings and LED indicators. Modules quickly snap into the SysFlex rack mount and each is firmly secured with a single screw. The racking system segregates network and power wiring from the audio and digital audio connectors. For connectorized network audio endpoints and A/V system components that provide unparalleled performance and advanced features without giving up simplicity and ease of installation, SysFlex is the industry's best value.

APPLICATION: The SF-NP35E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage amplified output. The output provides 35 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module.

The SF-NP35E is equipped to operate from a PoE++ enabled network switch. The SF-NP35E may be powered from an external 24 Vdc power supply, available separately.

If a PoE++ powered device instantaneously demands excessive power from a PoE++ port, that port can shut off its output voltage, causing a prolonged disruption of the device operation. The SF-NP35E monitors the amplifier power and limits the current to protect the PoE++ port against shutting down even during extreme feedback or square wave modulation conditions. A red rear-panel PORT PROTECT LED flashes when the SF-NP35E reduces power consumption to prevent shutdown of the PoE++ port voltage.

The SF-NP35E is equipped with an internal VCA for setting the output level. A detachable terminal block provides for the connection of an external 10 KΩ potentiometer or a 0 to 10 Vdc control voltage. The amplifier gain remains at maximum when the VCA input terminal is not connected. RDL remote controls are available to provide single-turn, multi-turn (rotary encoder) or pushbutton (ramp or fixed level selection) user level control. VCA control insures long term noise-free level adjustment.

The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat for all levels of expected voice or music modulation. An LED MUTE indicator glows yellow when the output is muted. Valid synchronization to the Dante network is indicated by a green LED visible from the front of the unit.

The SF-NP35E is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of SYSFLEX products adds enormous flexibility in the design and installation of professional A/V systems.
