MTP R 15HD RSA D • Reference Information
Reference Information, cont’d
17
THD + Noise .................................. 0.15% @ 1 kHz, 0.3% @ 20 kHz at nominal
level
S/N
.................................................. >70 dB at maximum output (unweighted)
CMRR .............................................. >43 dB @ 20 Hz to 20 kHz
Audio output
Number/signal type ..................... 1 mono, balanced/unbalanced
Connector ....................................... (1) 3.5 mm captive screw connector, 5 pole
(uses 3 poles)
Impedance
...................................... 50 ohms balanced, 100 ohms balanced
Gain error ....................................... ±1 dB channel to channel
Nominal level ................................ +4 dBu (1.23 Vrms), -10 dBV (316 mVrms)
Maximum level .............................. >+14 dBu, unbalanced at 1% THD+N
Control/remote — external device (pass-through,
unidirectional or bidirectional)
Serial control port input/output 1 set of proprietary signals on a female
RJ-45 jack
Serial control port output/input RS-232 via 3 poles of a 3.5 mm captive
screw connector, 5 pole
N
The serial communications link is unidirectional only, transmitter
to receiver, unless the receiver's directional DIP switch has been
repositioned. The switch should be repositioned only when the receiver
is the only one in the system.
Baud rates ....................................... Up to 38400 bps at up to 1000' (300 m)
(Higher data rates and distances are
possible. Performance varies based on
baud rate and cable length.)
Protocol
........................................... Data bits = 5 through 8
Stop bits = 1 or 2
Parity = odd, even, none
Flow control = XON, XOFF, none
N
Protocol is mirrored between the transmitter and the receiver.
Serial control pin configurations Captive screw connector:
1 = TX, 2 = RX, 3 = GND
General
Recommended cable type ............ CAT 5/5E/6 (shielded or unshielded)
External power supply ................. 100 VAC to 240 VAC, 50-60 Hz, external; to
12 VDC, 1 A, regulated
Power input requirements
........... 12 VDC, 0.5 A
