----------------------------------
CONFIGURE PREAMP
(You already have an amplifier)
Your Receiver has speaker wire terminals powering two channels that's marked:
FRONT B, ZONE2, PRESENCE
These amplifier outputs can be configured for additional front height speakers above the display
(FRONT B),
ONE pair of Zone 2 speakers in another location (ZONE2), or ambience speakers elsewhere in your home theater area
(PRESENCE).
Since you are going to use those terminals for other speaker zones you first need to configure the preamp/controller to send the right signal to the amplifier section for those two outputs. I presume that the previous owner had already done this as he was using these amplifier outputs for zone two. However, you said you weren't getting any volume no matter how high you turned up the volume, so something's amiss somewhere in the chain of equipment. Making sure the preamp is configured properly for Zone 2 is the first place to start solving the problem. Read the instructions posted above in the attached thumbnails.
Once Zone 2 option is configured, turn on a signal like FM radio and test to make sure the Zone 2 amplifier is working. To test the zone two amplifier, hook it up directly to another speaker in your system and see if you get sound. Check both channels. If you find the Zone 2 amplifier is broken, you can always buy a separate zone amplifier and use the RCA line level output jacks to hook it up.

CHECK SPEAKER SELECTOR
(If you have more than one Zone you need a Selector)
The amplifier section in your receiver will directly power only ONE PAIR of Zone 2 speakers. If you have other pairs of speakers around the house in other Zones, then you need a Speaker Selector as an interface between the receiver and the sets of speakers. A selector divides up the sound to the different inputs with on/off switches and/or volume knobs. MOST IMPORTANT, a speaker selector matches the impedance load of multiple speakers to the amplifier in your receiver so it doesn't damage the receiver. Most pair of distributed audio speakers present an 8 ohm load. When you double it to 2 pairs the load drops to 4 ohms. When you double it again to 4 pairs the load drops to 2 ohms. Each time you double the load like that, the amplifier tries to put out double the power, at least until it burns out. The speaker selector adjusts the impedance so that the amplifier always sees a nominal 8 ohm load with multiple pairs of speakers.
We are assuming that there is a speaker selector somewhere in the system. Just follow the wire that was going from the Zone 2 output terminals to whatever piece of equipment all the other zone speakers were hooked up to. That's your speaker selector. Some models need power, if it does, then check the power supply (usually a wall wart transformer). If there is still no sound, then try hooking the wires from the receiver directly to the wires from one zone (bypassing the selector and all the other speakers). If that works, then you need a new speaker selector. Check on audiogon and ebay for a used switch from Niles, speaker craft or OSD. Niles is the most expensive and probably the best built
