Rear Panel Controls
1) Power inlet:
The mains power supply (110~240V AC / 50~60 Hz) has to be applied
to this AC power inlet. The connection is made by an IEC power
connector and is fitted with a fuse. When replacing the fuse, make
sure that the value of the replacement fuse matches the value of the
original fuse. (T6.3AH/250V)
2) Binding post output connectors
Connection to the binding posts can be made with bare wire,
banana plugs, or spade lug terminations. Make connections to both
the channel 1 and channel 2 terminals for stereo or parallel mode,
or a single connection of channel 1 +(red) and channel 2 -(black) for
bridged mono mode.
3) Speakon output connectors
You can use these to connect each channel of Titan 621 to 8 ohms or 4
ohms loudspeakers. Using Speakon speaker cables, make connections
to both the channel 1 and channel 2 connections for stereo or parallel
mode, or to the bridge mode connector for bridged mono mode. (Mi-
nimum impedance 8 ohms bridge output.) Please use the side entry
positions with European models.
4) Crossover mode switch
This switch activates the filter or turns it off.
Full Range:
All 3 channels are not filtered, the same signal is sent to
all 3 outputs.
120Hz:
The integrated filter is active and the signal is divided
into two parts:
Channels 1 and 2 with highpass filter at 120 Hz
Channel 3 with lowpass filter at 120 Hz
5) Operation mode switch:
For every two channels is an “Operation mode switch” provided. By
means of this switch, the operation mode of the amplifier can be
selected between standard stereo mode, parallel mode and bridge
mode. For standard stereo applications, this switch should be turned
to center position for stereo mode.
6) Input connectors
Connect the input source to these electronic balanced combination
connectors using either XLR or ¼-inch TRS plugs. The ¼-inch TRS and
XLR plug is configured as follows:
Pin 2 (Tip) hot
Pin 3 (Ring) cold
Pin 1(Sleeve) ground
We recommend the use of balanced three-conductor cabling whe-
rever possible. Unbalanced two-conductor ¼-inch plugs can also be
inserted into these inputs, but you will get better signal quality and
less outside noise and hum if you use balanced lines. Stereo signal
should be connected to both the channel 1 and channel 2 input jacks.
However, when operating Titan 621 in bridged mono or parallel mo-
des, use the channel 1 input jack only.
