Radio Shack Pa 4-channel Audio Mixer Ssm-50 Reviews

No, and why would you want that. Anything off of eBay for $35 to $forty would be ameliorate. Behringer would even be improve.

Radio Shack's corporate mission argument is to make the crappiest stuff on the planet.
The i thing they do really well is honor their mission statement.

To answer your question, I see nothing virtually phantom in the specs. It'south powered by 1 9V battery, so phantom would brand the battery last about 5 minutes. No.

Pretty much.

I really HAD one of those (or very similar) as part of my 'studio in a bag' that I put together to lend to friends and others for pre-studio practice before going into a 'existent' studio with them the first fourth dimension back in the 80s. The studio-in-a-bag was that mixer and a pair of mics and some wires and maybe a inexpensive pair of headphones. They had to add ii recorders of some kind The concept was that they'd lay down their music tracks live and and so come back and and then overdub vocals during a ping pong. It was agreeable and it actually helped a lot of folks get their heads together I remember.

Merely, man, that lilliputian mixer is more than a bit of a joke.

How is a 9 volt battery going to be plenty ability for 48v phantom power? I don't know enough about electronics to wrap my head around that concept.

OP, for the same price, yous can get a Behringer Xenyx 802 USED on CL. I see them all the fourth dimension in my surface area. It'due south a way ameliorate mixer.

Agreed that this is not a good mixer, but 9V for phantom power is not a problem.

Most phantom powered stuff would probably run ok on 3V, and there are plenty of phantom power equipped devices that don't run the full 48V - often considerably less.

Yet - a designer can always use voltage multipliers to turn 3V or 9V into 48V if that was actually required. Hands washed if you want to spend the money on the components. The bodily Power requirements is tiny - Power existence Watts being Volts x Amps. So very little current is needed, so it could be done if it was justified.

Clearly non justified in this case. If you need a inexpensive mixer with phantom power, expect at Mackie or similar - endeavor to do meliorate than Behringer.

But if you lot are recording to a reckoner or something, I would question the demand for a mixer at all - get a good interface and practise all your mixing ITB. At the low upkeep cease digital far outperforms poor analog.

Those who don't empathise how a ability supply of a given voltage can be stepped up in voltage (at the 'expense' of available amperage) should probably become back to their eighth grade electric shop workbook. I'd earlier posted a link to Ohm'due south Law simply realized that would just confuse a lot of folks.

And here we are in these forums ofttimes discussing digital recording technology with folks who don't empathise basic electricity. Modern life is... amusing.

Indeed. The Bellari MP105 (call up that'southward the model) uses a wall wart and supplies 150 volts to the tube.

I've got i of those Xenyx Behringer 1202's for small gigs. The congenital in FX are foreign, how they are carve up between the stereo channels. I'd much rather just accept mono FX for live. But it sounds smashing, and with a pair of EV ZLX15P's, makes a very decent small PA. It's xc bucks, and I've seen them used for $l.

Maybe we tin can assistance with the "caput rapping"

It'due south actually fairly simple to convert a 9 volt DC supply to a regulated 48 volt phantom power source. There are agile circuits generally called "DC to DC Converters" and sometimes more specifically called "Voltage Multipliers", Accuse pumps", "Voltage Doublers", Voltage Quadruplers", etc. The excursion typically uses a transistor switch to convert the low voltage into a high-frequency square wave or a pulse train and and then a series of diodes and coupling capacitors to "multiply" that voltage to a higher level. A simple pace-up transformer tin can besides be used, simply that may be more expensive, heavier and have up more room. Some capacitor mics even include internal voltage multipliers to increase the capsule bias voltage to well above 48 volts for amend functioning.

There are excellent, very high quality outboard phantom ability supplies similar the Denecke PS1A and PS2 which can power (1) or (2) mics from a single nine volt bombardment for several hours and which provide better "quality" (lower noise and ameliorate regulation) than most phantom power supplies in line operated mic pres and mixers. They are widely used in the video and film industries ahead of portable mixers without congenital-in PP when powered mics are used.

Finally, the vast numbers of widely used, low-cost 2X2 "hobbyist" USB or FireWire powered interfaces (like a Saffire 2i2 or a Presonus Audiobox) all have built-in "voltage multipliers" to provide PP for their mic inputs. Call back almost information technology: the simply power source those interfaces have is the +5 Volts on the interface digital I/O cablevision.

Hope this helps a piffling.

Information technology's really fairly elementary to convert a 9 volt DC supply to a regulated 48 volt phantom power source. In that location are active circuits generally called "DC to DC Converters" and sometimes more specifically called "Voltage Multipliers", Charge pumps", "Voltage Doublers", Voltage Quadruplers", etc. The excursion typically uses a transistor switch to convert the low voltage into a high-frequency foursquare moving ridge or a pulse railroad train so a series of diodes and coupling capacitors to "multiply" that voltage to a college level. A simple step-upward transformer can too be used, but that may be more expensive, heavier and take upward more room. Some capacitor mics even include internal voltage multipliers to increase the capsule bias voltage to well in a higher place 48 volts for better performance.

There are splendid, very high quality outboard phantom power supplies like the Denecke PS1A and PS2 which can power (1) or (2) mics from a single 9 volt battery for several hours and which provide better "quality" (lower noise and ameliorate regulation) than most phantom power supplies in line operated mic pres and mixers. They are widely used in the video and picture industries ahead of portable mixers without built-in PP when powered mics are used.

Finally, the vast numbers of widely used, low-cost 2X2 "hobbyist" USB or FireWire powered interfaces (similar a Saffire 2i2 or a Presonus Audiobox) all have born "voltage multipliers" to provide PP for their mic inputs. Think well-nigh information technology: the but power source those interfaces take is the +5 Volts on the interface digital I/O cablevision.

Hope this helps a little.

I plant your generous efforts at caption valuable, for sure. Merely I'm agape the party you're addressing may well need to go back to her basic electrical theory and work up from the at that place.

Far likewise many folks -- and I've been as guilty as anyone or worse at various times in the past -- have a tendency to 'black box' concepts they don't understand and rush ahead, counting on some sort of vague practical understanding of how the 'outside' of the black box works to go them past their lack of understanding of the fundamentals -- fundamentals which, if understood, would actually help them understand what they're doing at whatsoever betoken instead of working from guesses, assumptions, or worse, fundamental misunderstandings.

Sounds like yous've been hanging around also many elected officials.
