Pro Tools | MTRX SPQ Speaker Processing Card (not compatible with MTRX II)

The SPQ system consist of a DSP card that you can install in one of the 8 card slots of AX32. The SPQ Speaker Processor System is extremely flexible and you can match it to any speaker configuration, including immersive audio formats such as Dolby Atmos.

Features:

• DSP/FPGA Card for AX32
• Room Tuning with up to 16 Filters Per Channel
• Bass Management with Support for Multiple Subs
• 1024 IIR Filters
• 128 channels @ 48 kHz
• Sample Rates from 44,1 to 384 kHz
• Adjustable Latency up to 800ms Per Channel
• Speaker Match Between Various Immersive Audio Formats

Management of the controls is handled via the DADman control software, where you can configure processing for all output channels in the defined monitor profile - also on cue signals. Processing can be applied for room tuning, bass management and equalizing of cue and monitor signals. And you can easily save and recall all configurations in the DADman monitor profile.

The SPQ – Speaker Processor Card is mounted in the 8-slot card section of the AX32 base unit. Normally one card is installed, but if more channels are needed more cards can be installed. The SPQ card does not have any I/O connectivity as it is a pure processing card. The SPQ card provides filters for channel-based speaker EQ and well as Bass Management.

The SPQ – Speaker Processor Card can be configured to various different filter characteristics and channel layouts via the DADman control software and is all integrated and easily managed by the Pro|Mon monitor control section in DADman. The SPQ Card supports all the system sample rates and will reconfigure automatically and fast when sample rates are changed, with equal filters and delay independent of the sample rate. Delay can be set individually per channel as well as generally for a whole set of speakers to also accommodate lip-sync applications.

The SPQ setting is stored in the Pro|Mon monitor profile in DADman, and speaker settings can be recalled separately from stored monitor profiles for fast change of parameters.

Measurement of the speaker curves and frequency responses have to be done using a separate measurement program, as this is not a part of the SPQ and Pro|Mon functionality.
