OK - here we go - some new, very solid info on the JBL SDP75. I posted this in the dedicated Synthesis thread on the Speaker Forums as well - here's the direct link, if you want to join in there:
Here is some tantalizing new info about the JBL SDP-75 surround processor, based on a conversation I just had with those “in the know” at Harman. I can honestly say I am even more excited about this piece than I was previously. There are many, many impressive features and true performance upgrades over competing surround processors, so much more that I can now say that I genuinely feel that the SDP-75 also represents a tremendous value (yes, even at its price point). The SDP75 is so much more than just a surround processor with a higher channel count – it’s a true audiophile product with amazing versatility.
To get right to it:
The SDP75 - along with its cousin, the Trinnov Altitude - is the ONLY surround processor on the market that does not down-convert or re-sample incoming bitstreams – all processing is handled at the native incoming resolution / sample rate, resulting in higher transparency and much higher fidelity.
The SDP75 has Harman’s NEW target curves loaded in, based on the latest research undertaken by Dr. Toole and Dr. Sean Olive’s team—part of the amazing brain trust at Harman. These represent a significant improvement over the previous Synthesis target curves.
New Harman targets described as a “night and day” improvement over previous ARCOS / Synthesis targets during blind listening tests (which is truly impressive, since even the previous ARCOS EQ / targets were scientifically demonstrated to be considerably superior to competing systems during blind listening tests).
The SDP75 is capable of being calibrated using the Trinnov Optimizer microphone and software, and processed using Harman’s own targets and algorithm operation tweaks (in other words, they are using the power of the Optimizer in a different manner than Trinnov). A JBL SDEC Is no longer necessary – all processing can be accomplished inside the SDP75 at the native sampling rate and without additional A-D and D-A conversions, and at a cost savings of $8,000 to $16,000, depending on the number of channels. A calibration accomplished in this manner can be fully Synthesis certified when done by a JBL Synthesis or approved technician.
Almost any conceivable JBL Synthesis or Revel speaker configuration is available as a “preset” in the SDP75, allowing for speakers to be re-purposed for optimum performance no matter which immersive audio codec is chosen (Dolby Atmos, Auro3D, DTS:X). The SDP-75 can apply delays and volume level adjustments to “arrayed” speakers in non-native formats so that all speakers in a system can be employed to cover different format recommended speaker layouts. For example, the SDP75 will take advantage of, say, a 24 channel speaker layout to “map” appropriate sounds to each speaker no matter if the incoming source is Atmos, Auro3D, or DTS:X. The sound can be intelligently re-routed to the appropriate speakers by applying delays and level adjustments for true immersive audio no matter the input codec.
The SDP75 is available in 16, 24 and 32 channel configurations. To determine which is the right model for you, simply add up the number of speakers and subwoofers you will need / want in your system (or have a JBL Synthesis dealer work all that up for you).
Coming ability to lead in detailed anechoic data for each and every JBL Synthesis / Revel speaker model, for every channel (this will also allow the SDP-75 to handle proper EQ / processing for such speakers as the JBL M2 / LSR7 series without special amps or outboard processing)
SDP75-16 channels: $23,500
SDP75-24 channels: $28,000 (shipping in May)
SDP75-32 channels: $31,500
Hoping to have a demo unit in our showroom soon - time to start saving up!
