Sub-woofer Connections
When selecting cables for use with your PMC sub-woofer, ensure that they are adequately shielded, which is
particularly important if single-ended runs are used and that their construction is of a high enough standard to
withstand the rigors of everyday use.
First, decide which type of input you will be using:
Balanced (XLR)
Input Selector
: ‘BAL’ (switch in the out position. This can be found under the flap at the top rear of the unit)
The TLE1 can be connected to an amplifier, pre-amplifier, receiver or surround processor using balanced (XLR) inter-
connect cables. Balanced cables are recommended wherever possible due to their inherent superiority and noise
rejection, which is particularly important if long cable runs are required.
OR
Unbalanced / Single-ended (RCA/Phono)
Input Selector
: ‘UNBAL’ (switch in the in position. This can be found under the flap at the top rear of the unit
)
Single-ended (RCA) connections are still the most common method of routing signals from an amplifier, pre-
amplifier, receiver or surround processor to a sub-woofer. The hook-up method is exactly the same as that for
balanced inter-connects.
Connect one end of each cable to your processor, receiver or amplifier and the other to the TLE1
Note: Both types of connection cannot be used concurrently.
Tip: An inexpensive length of RCA cable can be used when experimenting with sub-woofer placement and then
replaced with balanced inter-connects – if supported by your hardware – once the final position has been
determined.
Do I use both left and right inputs?
If your processor only provides one sub-woofer output – sometimes labelled “LFE” or “SUB” – then a single balanced
or unbalanced cable can be used, connected to either the left or right input of the TLE1, it doesn’t matter which. If
a single unbalanced input is used, then it is recommended that the supplied RCA shorting plug is inserted into the
unused RCA socket. Stereo sub-woofer or stereo pre-amplifier outputs are also supported; requiring the use of two
lengths of cable (one for left, one for right), so that the sub-woofer reproduces the bass information from both
channels.
If you are using the sub-woofer in a two-channel system, it can be connected to any available pre-amplifier
output/s, provided the output is not of the fixed gain type (a tape record loop, for example).
