FAQ — JBL SDP-70
How many channels can the JBL SDP-70 process?
The SDP-70 provides up to 24 channels of high-resolution immersive audio processing. This makes it suitable for sophisticated theaters incorporating extensive surround and overhead speaker arrays along with multiple independently managed subwoofer channels.
Does the JBL SDP-70 have built-in power amplification?
No. The SDP-70 is an AV preamp/processor and requires external power amplifiers to drive the loudspeakers. It provides both balanced XLR and unbalanced RCA outputs for all 24 processed channels.
What is the difference between the JBL SDP-60 and SDP-70?
The primary difference is processing capacity. The SDP-60 provides 16-channel processing and 16 XLR/RCA outputs, while the SDP-70 expands the platform to 24 processing channels with 24 XLR and 24 RCA outputs. The additional channels make the SDP-70 better suited to larger immersive systems requiring more surround, height, or subwoofer channels.
Does the SDP-70 support Dirac room correction?
Yes. The SDP-70 supports Dirac Live Room Correction and Dirac Live Bass Control, providing sophisticated tools for optimizing speaker response, timing, bass integration, and overall performance within the listening environment.
What is Dante and why is it useful?
Dante is a professional digital audio networking technology that transports multiple channels of high-quality digital audio over compatible network infrastructure. In an advanced installation, Dante can simplify signal distribution between the processor, compatible amplifiers, and other networked audio components.
Does the SDP-70 support 8K and 4K/120Hz video?
Yes. Its HDMI 2.1a platform supports video resolutions up to 8K at 60Hz and 4K at 120Hz, along with modern HDR and gaming features including Dolby Vision, HDR10+, HDR10+ Gaming, HLG, VRR, and ALLM.
