The Radio Design D-SH1M is a surface mounted, stereo / mono, headphone amplifier for audio installations of any kind. Museum exhibits, private audio monitoring installations, and listening stations are among some of the possible applications the D-SH1M is suitable for. The module mounts conveniently in a precut opening in a wood or metal enclosure or in various RDL mounting accessories.

The dual-channel headphone amplifier features balanced/unbalanced left and right inputs that accept operating levels between -20 dBV and +20 dBu. Two recessed slide switches located on the side of the rear enclosure are set prior to mounting the module. One of the switches sets the input sensitivity, the other selects between stereo and mono operation. The front panel level control is a long-life potentiometer. Because audio does not pass through this control, it can provide years of noise-free level adjustment.

Because audio does not pass through the Radio Labs D-SH1M control, it assures years of noise-free level adjustment. This, with the integral long-life VCA stereo level control (with balanced or unbalanced inputs) means you will have a durable and dependable amplifier.

It comes with built-in headphone adaptability. The output amplifiers deliver more than 50mW into either high or low impedance headphones through a 1/4" (6.3mm) standard headphone jack.

This unit adapts to studio or office. This Radio Design amplifier is designed with the convenience of APPFLEX Mounting allowing panel-mounted or wall mounted functionality.

Q: 5. Can speakers be one of the outputs from this device?

A: A pair of amplified speakers may be connected.

Q: 6. If I get the correct cables could I send the signal from a crosley turntable to this, then to a receiver? The ol' yamaha is running down at -18db to be able to hear the records at a decent volume from the passive speakers it's driving... I need it amped up a bit before it gets there methinks.

A: I can't answer from knowledge of the specific turntable, but every phono I've ever known for the past 40 years requires a phono preamp for two reasons. 1) The signal level is way, way too low for directly connecting to a headphone amp or any line-level device. 2) Most importantly phonographs are all recorded with a very treble-skewed EQ according to the standard RIAI curve, a phono preamp is designed to nullify that curve by being exactly opposite towards a heavy bass response. In short, there is no substitute for a phono preamp. Make sure it is labeled and defined as phono preamp.

Q: 7. Can I use it for Live Church Service?I want to take the Line Out of my Church Amp and get 4 Outputs to put 4 Powered Speakers around the Hall.

Q: 8. How long the mini cable?

A: The included mini cable is 1.5 meters in length. (Just under 5 ft.)

Q: 9. Can you daisy chain two of these? I have one already and need more outputs.

A: Sure you can.

Q: 10. What cables do I need and where do I hook My Behringer 800 headphone amp to ?

A: You will need 1/4 cables.The back of the headphone amp is 1/4 TRS cable. This will be put in line to your interface or audio mixer. Most often will be 1/4 TRS on the interface or mixer. Be sure that you won't need 1/4 from headphone amp to XLR on interface or mixer.Think about how far the amp will be from said gear to order,just enough length in your cables.I bought 6 cables since my amp sits on top of interface.Hope this helpsDanny
