USER MANUAL SS2V70-200W OSD Audio

The SS2V70-200W is a unique 70V Speaker Selector featuring...

2 independent Zones each controlled by a 200 Watt 70V Mono Volume Control featuring a Rotary Style Knob. Each zone has On/Off switch as well. The unit has a single 2 conductor input and direct pass through allowing to stack additional SS2V70 Speaker selectors only limited by your application. Standard 70V rules apply to the number of speakers used per zone, matching the available power from the 70V amplifier.

Front Panel

1. Zone 1 On/Off Switch
2. Zone 1 Volume Knob
3. Zone 2 On/Off Switch
4. Zone 2 Volume Knob

Note #1: The Zone 1 & 2 On/Off button allows you to turn each zone off independently of the volume knob

Rear Panel

1. Zone 2 Speaker Output
2. Zone 1 Speaker Output
3. Input From Amplifier
4. Straight Thru Output

Note #2: The Thru output comes directly from the Input, it does not go through the transformer allowing you to stack multiple SS2V70.

Power Rating

The Internal Volume Controls (2) are rated at 200W so the speaker(s) connected to it needs the transformer setting to be equal to or less than the rated watts of each zone. You can have multiple speakers connected to one zone but total wattage must 80% or less than the rated Wattage of the each of the internal 200 Watt Volume Controls.

Picking the Right Distribution Amplifier

To start with the Amplifier must have a 70Volt output. It must have an output power rating equal to or greater than the total wattage of the system once you have calculated what each speaker should be set to and the total sum of those settings. If you had four speakers at 5 watts each (20 total) and one speaker set to 10 watts (20 + 10 = 30) your amplifier must be rated at least 30 watts minimum. If you had five speakers at 10 watts each (50 total) and another 5 five speakers at 5 watts each (25 + 50 = 75) you would need a amplifier rated at a minimum 75 watts.

Some companies recommend the total should be closer to 80% of the minimum rating of the amplifier. It is also a good idea to install an amplifier with more than enough power in case you want to add more speakers later.

Key Point: The Power rating of the amplifier is determined by the transformer settings, not the attenuator Rating, The rated power of the Attenuator is based upon the minimum setting of the transformer taps which have to be equal to or less than the rated wattage of the respective SS2V70 Attenuator.
