Features & Specifications

The OSD PAM-1270 is a major step forward in installation amplifiers technology. It features either Twelve Zone mono channels (70V) or Six Stereo Zones (8/4 Ohm) or a combination of both 70V and 8/4 Ohm 85% class D design technology, can operate as 6 independent Stereo Zone amplifiers. Self-explanatory Input and Output connections are easy to follow since any of the 12 mono amplifiers can be connected to either 70-Volt, 8-Ohm or 4-ohm speaker circuits.

Each of the 12 mono amplifiers has their own input and output connectors and level Controls. Up to 6 stereo Zones (4-ohm or 70-Volt at 50Watts/channel), 6 mono/bridged Zone amplifiers (110 Watt bridged 8-ohm). Each zone can be configured independently allowing a combination of Stereo 4-ohm or 70Volt and Mono/Bridged 8-ohm. Dual-function LEDs on the front panel provide both activity and Clip indication for each pair of amplifiers. Additional features selectable on the back panel include Six Limiter Button and Six Stereo/Bridge modes for the individual Stereo or Bridged Mono Zones. The Channel Input Line/Bus switch selects between either the Bus Input (button depressed) or the individual Zone's Input signal.

The PAM-1270 includes a RS232 for IP interface with Home Automation Systems Additional features include: any amplifier with no signal at its input is automatically shut off and the CA1250 is Multi Voltage; able to operate either on 110V-120V/60Hz or 220V-240V /50Hz AC mains.


Other Product Info

Physical location and mounting

The PAM-1270 is convection cooled. That is, it depends on the natural free flow of air up through the slot perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling.
2. The PAM-1270 is designed for mounting into standard 19" (483mm) racks or on flat horizontal surfaces.
3. If mounted in an equipment cabinet or other confining location, allow at least 2 inches of space above the top cover (see Fig. above). Be sure there are large openings in the shelf below the unit and in the cabinet to allow the entry of cool air and the escape of warm air.
4. If the cabinet contains other heat generating components or you are using several PAM-1270’s, you will have to pay even closer attention to adequate ventilation.
5. Do not hesitate to use fans (quiet, boxer type), if necessary, to ensure a constant flow of air through the CA1250's and the other heat generating components.
6. When installing the PAM-1270 in a rack, please use racks that feature rear support provision. Adding a single RU (Rack Unit) above and below the PAM-1270 will improve convection in heavy use applications. [One Rack Unit size = 1-3/4" (44.5mm) in height].
7. In some installations, you may have large bundles of wire and cable to accommodate audio and speaker connections. Be sure to allow enough room for the leads and dress them in such a manner so as not to block airflow.

The OSD PAM-1270 includes a full function Remote Control. A custom IR kit is being developed for the interface so you can control the functions of the PAM-1270. the IR codes are available so you will be able to program for a Universal Remote Control. Each Stereo Zone/Bridges Mono features a connector with IR +, Ground, Mute and Status Port
Master Global Trigger In (+3 to +30V DC) and Trigger Out (+12V DC) for turn on of the PAM-1270 or external components equipped with 12 volt trigger. Plus individual Line/Bus Triggers input per Stereo Zone/Bridged Mono Zone.

looking at this to run 70v , so it is simple to assume you have 12 outputs at 30w each with 12 mono inputs as well?
1 Answers
Hi Mark: Yes this has 12 mono inputs or six stereo inputs. It also has a bus system that has a mono input so you can have 12 channels from the bus or any combination of bus channels and direct input. You can also do either 70V or 8 ohm or a combination of both. You can also bridge two channels together. The Amp includes a 6 zone IR kit that hard wires into input connector for each zone. That works for all 6 zones. You can add individual IR kits for each zone, these are optional and there is a charge for the additional IR kits. The unit also has RS232 connections. Checkout the owners manual on the web page for info on the IR, RS232 and Bus input. TL/4758

I am planning to install 6 zones with 5 stereo speakers in ceiling (5 rooms) and 2 "mono stereo" in ceiling (2 bathrooms) I have been looking at the Denon Heos drive where I can use an App to controll every room seperatly (different music in all rooms) or combine all the rooms to be able to play the same music in all rooms (for example Spotify). So my question is if the PAM1270 can do the above? Or do I need to combine it with a music streamer of some sort or something else? Thanks, Alex

Hi Alex: I am not sure if the PAM 1270 would work for your application. I am pretty sure for you to control the DENON Heos for all six zones you will need at least 6 individual links. I am assuming you will have a pair of stereo speakers in 4 rooms and 2 pair in the fifth room. Plus a single stereo/mono speaker in each of your two rooms. That would actually be 7 zones, since each of the stereo/mono speakers are connected to a stereo signal one left and one right to input of the Dual voice coil stereo/mono speaker. Now if you were connecting two speakers in your master bedroom you could connect the master bedroom in parallel to the master bedroom which also means it would play the same music for both but you would now have 6 zones. And you could connect and control six zones with six zones but you would have to sync all six to make them play the same throughout the whole house. That would be a question for DENON. There are other ways of doing this manually but with only two sources based upon what else we can offer. You know Denon has a Heos AMP similar to the SONOS Connect Amp which you would need six or even 7 of them to control your setup. That would be $3,000 to $3,500 US before adding any speakers. Maybe Denon has something else I do not know about but that is what the offer here in the US. Let me know if we can help you further. TL/4550

I bought this item to conect to a Yamaha RX V679 receiver and to make 6 zones for my home. I want to be able to turn and off and to pop up and down the volume of each zone. I understand the IP Addressable RS232 will allow me to do this if I buy a serial controller and a license software to manage this (but his can be pricy just for pup and down volumen and swich off the zones). Anyone can recommend a cheaper solution?
1 Answers
Hi Oscar: A couple of things you can try, check out "simple control": They may have some sort of solution for you on the RS232, possible tie in with a computer/laptop. Most of the older laptop actually had a RS232 connector built in. Now they sell RS232 to USB adapters for interface with your computer/Laptop. Here is a link for one of these adapter cables along with a interface you download. Also there is a remote control that is included with the Amplifier which you can use or a list of all the master code and Hex codes for programming a Universal remote. We can help you jury rig an IR receiver kit where the sensors are hard wired into each of the six zones. You would then connect to the universal Bus so all channels see the same source. You can hard wire each zone as agroup or individual. Please let us know what else you find and contact me at Good Luck TL/3881

Flexible installaltion
I've been waiting for this multi channel amp which can combine 70v and 8 ohms in one unit for a long time. Often we have to buy couple of 70v amps for restaurant setup which add cost quickly, by using this unit I can setup 4x zones in 70v amps to power 70v speakers and use the other 2x zones in 8 ohms to power subwoofers. It is pretty easy to program the source, volume through URC.
ProsHeavy Duty Configuration flexibility 70v and 8 ohms Input choices Programmable
ConsVery heavy
Best UsesCommercial installation require multi zone sound setup
