Ask about rental or technical support
Start with date, venue and approximate needs. We assess options, configuration and operation; availability and terms are confirmed in the proposal.
Model and connections
Identify model and line path. THRU/OUTPUT connectors and THRU/DSP OUT selection must match the actual diagram. D-XSUB, crossover and cardioid mode serve different purposes; similar panels do not justify copied settings.
Prepare and check
We can assess distribution, power, configuration and operation from date, program and sketch. Separate acoustic design from physical installation with applicable accessories, transport and validation.
We can assess rental, purchase, integration or support. Start with date, venue, program and approximate sources; quantities, compatibility, availability and terms are confirmed in the proposal.
Questions and decisions
How does it integrate with Yamaha tops?
Record top models, inputs and filters applied by each cabinet/sub. Follow exact-system preset/diagram and check each output’s content rather than assuming XLR means the needed filtering. Listen separately and together at protected level; save settings and alignment ownership. Different top generations require their own documentation.
Why is bass strong on stage but weak in the audience?
Map listening points, sub locations/orientations and feeds. Compare the same reference at stage/audience positions; a weak point may reflect interaction and room effects rather than insufficient power. The technician assesses locations and a documented arrangement, including cardioid where appropriate. Do not rotate cabinets or reverse polarity at random. Validate every required zone.
