Parasound Zonemaster Model1250 Multichannel Amplifier gets rave reviews on AVHub

Parasound ZoneMaster Multichannel Amplifier Model 1250 – AVHub Review

Let’s be bold here and propose something — you can never have too many amplifiers! Even if your principal system is an astonishingly high quality audiophile set-up, what about the rest of the house? Or what about the 11 channels required for a full (or 7.1.4 at least) Dolby Atmos system?

Well, the extremely flexible can deal with just about all these requirements.

EQUIPMENT
This is a 12-channel power amplifier which provides enormous flexibility in how it can be used. For one thing, it need not be 12 channels.

It can be 11, or 10, or any number down to six. You don’t waste the leftover amplification —the 12-channels are grouped as six ‘zones’, each with a left and right channel, and each zone can have its two channels bridged to one, for higher power output.

Each channel can be entirely independent, even to the point of having its volume set separately to all the others. Each pair of channels can, as mentioned, be bridged, or can be set to mono (i.e. with the left and right signals mixed down to one signal, and then output by both left and right channels). Each zone (pair of channels) can be grouped with others to one of two separate buses. All channels can be switched on manually or by means of an external 12V trigger, or each zone can have its own 12V trigger or be set to automatic signal detection.

Are you starting to get a sense of the flexibility available here?

Let’s consider one scenario. You have a 7.1-channel home theatre receiver with Dolby Atmos support. You can use four of the 1250’s power amps for the four ceiling or Atmos-enabled speakers, for full 7.1.4 Dolby Atmos. You can also plug the receiver’s Zone B outputs into one of the bus inputs and have it go to up to eight other speakers (or more, but we’ll get to that).

Here’s another: perhaps you want to use one of the multiroom streamers which are proliferating at the moment. You might use a system that has multiple source components, or one of the PC-based multichannel source devices. Either way this amp will power speakers throughout your home, grouped entirely according to the capability of the sources and your preferences.

So, what about those dozen amplifiers? They are Class-D units, which means amongst other things that their negative terminals are not grounded, so double the care with speaker wiring is required. Each is rated at 50W into eight ohms, full audible bandwidth, with all 12 channels running. Parasound rates the THD at less than one per cent at full power, and less than 0.05% at ‘typical listening levels’.
