5. Connections
5.1. Signal grounding
There is no ground switch or terminal on the TDC
series amplifiers. All shield terminals of input
connectors are directly connected to the chassis.
This means that the unit’s signal grounding system is
automatic. To limit hum and/or interference entering
the signal path, use balanced input connections.
In the interests of safety, the unit MUST always
operate with electrical safety earth connected to the
chassis via the dedicated wire in the 3-wire cable. (ref.
Chapter 4:3. AC mains supply.) Never disconnect the
ground pin on the AC mains power cord.
5.2. Analog balanced input
Balanced analog inputs are provided with two XLR
female connectors. Refer to Panel D for proper
pinouts.
5.3. Analog unbalanced inputs
Unbalanced analog inputs are provided with two RCA
connectors. Refer to panel D for proper RCA pinouts.
5.4. Analog balanced output (through)
Balanced analog outputs for sending the signal to
another amplifier are provided with two XLR male
connectors. Refer to Panel D for proper pinouts.
5.5. Loudspeaker connections
TDC-1200W,
TDC-3200W
CLASS 2 WIRING
Phoenix (Euroblock) terminal with 4 pins is provided
for loudspeaker connections. Refer to Panel D for
proper connections for single channel mode and
bridged mode.
To remain within safe operating conditions, when
using low impedance loads - i.e. 4 Ohm or less (8 Ohm
or less in bridge mode) - connections must be made
with a four-wire cable. Use suitable wire gauges to
minimize power and damping factor losses in speaker
cables.
5.6. Ethernet connection
Ethernet connection is provided via the rear port
labeled “RS485 ETHERNET“.
MAG Cinema recommends the use of Ethernet
Cat5 straight-through - patch - cables with pin/
pair assignments TIA/EIA-568-B, i.e. T568B (refer
Panel D).
