APPENDIX B: MINA SPECIFICATIONS
ACOUSTICAL
Operating Frequency
Range
66 Hz – 18 kHz
Note: Recommended maximum operating frequency range. Response depends on load-
ing conditions and room acoustics.
Frequency Response 70 Hz – 17.5 kHz ±4 dB
Note: Measured free field with 1/3 octave frequency resolution at 4 meters.
Phase Response 1 kHz to 18 kHz ±30°
Maximum Peak SPL 128 dB
Note: Measured with music referred to 1 meter.
Dynamic Range >110 dB
Horizontal Coverage 100°
Vertical Coverage Varies, depending on array length and configuration
Crossover 760 Hz
Note: At this frequency, the transducers produce equal sound pressure levels.
TRANSDUCERS
Low and Low-Mid
Frequency
Two 6.5” cone drivers with neodymium magnets
Nominal impedance: 4Ω
Voice coil size: 1.5”
High Frequency One 3” compression driver
Nominal impedance: 8 Ω
Voice coil size: 3”
Diaphragm size: 3”
Exit size: 1.2”
AUDIO INPUT
Type Differential, electronically balanced
Maximum Common
Mode Range
±5 V DC
Connectors XLR female input with XLR male loop output
Input Impedance 10 kΩ differential between pins 2 and 3
Wiring Pin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamp network to provide virtual ground
lift at audio frequencies
Pin 2: Signal +
Pin 3: Signal –
Case: Earth ground and chassis
DC Blocking Differential DC blocking up to maximum common mode voltage
CMRR >50 dB, typically 80 dB (50 Hz – 500 Hz)
RF Filter Common mode: 425 kHz
Differential mode: 142 kHz
TIM Filter <80 kHz, integral to signal processing
Nominal Input Sensi-
tivity
0 dBV (1.0 V rms, 1.4 V peak) continuous average is typically the onset of limiting for
noise and music
Input Level Audio source must be capable of producing +20 dBV (10 V rms, 14 V peak) into 600 Ω to
produce the maximum peak SPL over the operating bandwidth of the loudspeaker
