Music

Setting a trigger mode switch to MUSIC position, sets the LDS16-40 zone-amps into auto-on- standby power control mode. Each zone-amp can sense, individually, a very low level music signal fed to its signal input, which will turn the amplifier into an active state and will play the music. When the music stops and no further signal is received for more than 10 minutes, the zone-amp will turn into a standby mode, which cuts off the power consumption substantially and the green LED will become dim. The zone-amp will wake up from the standby mode, or sleep mode, whenever the zone receives a music signal again.

12V

Setting the trigger mode switch of a zone-amp to 12V allows the power-on-standbyfunction of that zone-amp to be controlled by a 12V DC voltage connected to the 12V input jacks of group A and group B amplifiers. When 12V DC is present at the 12V trigger input jacks, the zone-amplifiers will turn on, and when the 12V disappears, the zone- amps will enter the standby mode momentary. Under standby mode, no music signal will go through that zone-amps and there is no output sent to the speakers. The zone-amplifiers will wake up from the standby mode whenever the zone receives a 12V trigger input.

Note that the 12V trigger input jack of group A is not internally connected to the 12V input jack of group B. A cable must be connected from the trigger output jack of A group to the trigger input jack of B group, if amps in both groups are to be triggered simultaneously by only one 12V trigger source.

Speaker Terminals and Speaker Loads

Each LDS16-40 provides one set of speaker terminals per zone for left and right speaker connections. When operating a zone amplifier under a stereo or mono mode, use only a speaker of 4 ohms or greater impedance for your installation. But when operating in BRGD (bridge mode), use only a speaker of 8 ohms or greater impedance.

Stereo/Mono/Bridged Switch

Stereo

Setting the switch to STEREO operates a zone amplifier, in a regular 2-channel, stereo mode.

Mono

Setting the switch to MONO sums the left and right inputs together and plays the same signal to both the left and right speakers.

Bridging

Setting the switch to BRGD operates a zone amplifier in the bridged mode, which turns the output of the left channel into the same signal as the right channel, but in the opposite polarity. Under this bridged mode, a speaker of 8 ohms minimum impedance can be connected between the positive (marked “+”) polarity of the right speaker terminal and the positive polarity (marked “+”) of the left speaker terminal in order to receive a two-times output voltage (for higher power output). The positive polarity of the speaker should be connected to the “+” terminal of the right channel for the speaker to be in the correct phase.
