[. . . ] Switches on the bottom panel allow to select a nominal level of +4 dBu or ­20 dBu for each channel and ±12 dB trim pots on the front panel make perfect level matching easy. LEDs on the front panel indicate signal presence for each channel. Ground lift switches are available on each channel or globally for eliminating ground loops. between +4 dBu and ­20 dBu channel on front panel t Signal LED for each channel t Ground lift switches for each functionality: Input signals can be routed to multiple output channels through switches (RCA to XLR and XLR to RCA) channel and master switch AC adapter needed t Internal power supply, no t 1 U rack-mountable chassis LA-80MKII t 8 channels with unbalanced RCA inputs and balanced XLR outputs t Distribution amplifier functionality: Input signals can be routed to multiple output channels through switches LA81MKII t 8 channels with balanced XLR inputs and unbalanced RCA outputs functionality: Input signals can be routed to multiple output channels through switches t Distribution amplifier LA-40mkiii · LA-80/81mkii Unbalanced/Balanced Line Converters Specifications Inputs and outputs Inputs (unbalanced) Input impedance Nominal input level Maximum input level Indicator detection level Outputs (balanced) Output impedance Nominal load impedance Minimum load impedance Nominal output level Maximum output level Inputs (balanced) Input impedance Nominal input level Maximum input level Indicator detection level Outputs (unbalanced) Output impedance Nominal load impedance Minimum load impedance Nominal output level Maximum output level RCA jacks 23 kOhm (when all INPUT LINK switches are OFF) 5. 7 kOhm (when all INPUT LINK switches are ON) ­10 dBV, ±1 dB +4. 8 dBV ­36 dBV or more (OUTPUT LEVEL switch set to +4 dB or ­20 dB) XLR-type connectors 94 Ohm 10 kOhm 600 Ohm +4 dBu, ±1 dB (OUTPUT LEVEL switch set to +4 dB) ­20 dBu, ±1 dB (OUTPUT LEVEL switch set to ­20 dB) +23 dBu XLR-type connectors 54 kOhm (when all INPUT LINK switches are OFF) 6. 7 kOhm (when all INPUT LINK switches are ON) +4 dBu, ±1 dB (INPUT LEVEL switch set to +4 dB) ­20 dBu, ±1 dB (INPUT LEVEL switch set to ­20 dB) +30 dBu (INPUT LEVEL switch set to +4 dB) +8 dBu (INPUT LEVEL switch set to ­20 dB) ­22 dBV or more (INPUT LEVEL switch set to +4 dB) ­46 dBV or more (INPUT LEVEL switch set to ­20 dB) RCA jack 200 Ohm 10 kOhm 1 kOhm ­10 dBV, ±1 dB +18 dBV Audio performance TRIM range S/N ratio (at nominal levels, INPUT/ OUTPUT switches set to +4 dB) Total harmonic distortion (1 kHz, at nominal levels) Frequency response (at nominal levels) Crosstalk (1 kHz, nominal levels, 600 Ohm load) ±12 dB 90 dB(A) (20 kHz LPF) 87 dB(A) (20 Hz HPF and 20 kHz LPF) 0. 005 % or less 20 Hz ­ 100 kHz, ±3 dB ­90 dB Other specifications Power requirements Power consumption Dimensions (W x H x D) Weight 100­240 V AC, 50/60 Hz 6W 483 mm x 44 mm x 280 mm 3 kg Level and Link switches on the units' bottom side LA-40mkiii LA-80mkii LA-81mkii © 2009 TEAC Europe GmbH All Rights Reserved.
