Clipping Indicators 
Two front panel LEDs (one for each channel) flash to indicate when the amplifier is “clip- ping” or being asked to deliver more output current than it is capable of delivering. Clip- ping will cause distortion levels to increase.
Occasional brief clipping on the loudest mu- sical passages is acceptable. However, sus- tained or frequent clipping is one of the most common causes of speaker damage and should be avoided.
Should this occur, either reduce the overall gain of the system by turning down the master volume control on your preamp. Alternatively, you may wish to permanently reduce the gain of the amplifier using the front panel level controls (see previous section).

The nominal impedance of the loudspeaker(s) connected to the
•Stereo mode: minimum 4 ohms
•Bridged Mono mode: minimum 8 ohms
•Parallel Mono mode: minimum 2 ohms
When driving multiple pairs of speakers con- nected in parallel, the effective impedance the amplifier sees is cut in half. For example, when driving two pair of 8 ohm speakers, the am- plifier sees a 4 ohm load. When driving mul- tiple speakers in parallel, select speakers with a nominal impedance of 8 ohms or higher.

Polarity and Phasing
The polarity – the positive/negative orienta- tion of the connections – for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the polarity of one connection is mistakenly reversed, bass output will be very weak and stereo imaging degraded. All wire is marked so you can iden- tify the two conductors. There may be ribs or a stripe on the insulation of one conductor. The wire may have clear insulation with dif- ferent color conductors (copper and silver). There may be polarity indications printed on the insulation. Identify the positive and nega- tive conductors and be consistent with every speaker and amplifier connection.
Speaker Connections

These speaker connectors accept bare wire, connector lugs, or “banana” type connectors (except in the European Community countries where their use is not permitted).
Route the wires from the
English
If you are using banana plugs, connect them to the wires and then plug into the backs of the speaker connectors. The collars of the speaker connectors should be screwed in all the way (clockwise).
If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the speaker connectors, separate the wire conductors and strip back the insu- lation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn counterclockwise) the speaker connector col- lar. Place the connector lug around the shaft, or insert the bundled wire into the hole in the shaft. Turn the collars clockwise to clamp the connector lug or wire firmly in place.
NOTE: Be sure there are no loose wire strands that could touch adjacent wires or connec- tors.
In Stereo mode: Connect the left speaker to the pair of speaker connectors labeled CH1. Connect the right speaker to the speaker con- nectors labeled CH2. Follow the labels printed above the connectors and make sure the BRIDGE MODE switch is set to the NORMAL STEREO position. (See Figure 2)
In Bridged Mono mode: Connect the posi- tive terminal of the speaker to the speaker con- nector labeled BRIDGE +. Connect the nega- tive terminal of the speaker to the speaker con- nector labeled BRIDGE
In Parallel Mono mode: Connect the speak- ers in the same fashion as in the Stereo mode. You can use the connectors for either chan- nel or both – the same output signal is present at both pair of connectors. (See Figure 2)
