Incognito LM10 INTRODUCTION SPECIFICATION Thank you for purchasing this Cambridge Audio Incognito product. The LM10 Local Input Module is an in-wall module that allows the user to add an additional local source to those distributed by the AH10. Max line level inputs The local source may only be heard in the room where it is connected and the corresponding sub-zone (if connected) and is not distributed to other rooms. LM10s can be fitted in as many rooms as are desired.

MOUNTING THE LM10 Locate the LM10 near the local source. Check all connections and test the system’s operation before installing the LM10 into the wall. Using the included hardware, install the LM10 into a standard electricians back-box (pattress) (LM10-EU=UK47mm depth single gang, LM10-CU=USAtype J-box 50mm). Important Care should be taken in choosing a site for the LM10, ALWAYS refer to the precautions later in this guide. Bear in mind that any local sources will likely require mains power.
Incognito LM10 SAFETY PRECAUTIONS Avoid placing the LM10 near to dimmer switches or other items, which generate a lot of electrical noise. Avoid fitting the LM10 in areas of high humidity. The LM10 runs on 24V DC supplied through the connecting cable. As such there is no mains voltage present in the LM10 and the unit is often safe to fit in areas where only extra low voltage (ELV) equipment is permitted.
CAT-5 CONNECTIONS A Cat-5 cable is used to connect the LM10 to a keypad output on an AH10 hub and to a KP10 amplified control module. Use Cat-5 cables (use EIA/TIA 568A RJ-45 wire configuration, see page 7) to connect from the hub to a LM10 wall plate (optional), and then wire from the wall plate to the KP10 (see opposite diagrams). The LM10 has punchdown connectors for the eight individual conductors of the Cat-5 cable, use a punchdown tool (LM10-EU=Krone, LM10-CU=110+ blade) to insert conductors.

CAT-5 CONNECTIONS CONTINUED It is possible to add up to two LM10 units per main zone. This gives you the option to listen to either one by selection from the keypad or LR10 remote control (Local1/Local 2). The module needs to be told whether there are one or two LM10’s present. Dual LM10s fitted in a single zone Connect the LM10s as shown in the opposite diagrams. Local Source 1 – Switch over SW1 (LC1) to the ON position and SW2 (LC2) to the OFF position.

Note: If using an LR10 to select the local source, this will ONLY select Local 1 as default.
Incognito LM10 SOURCE ROTATE FOR LOCAL 1&2 ON THE KEYPAD Note: This feature is only available if the KP10 is part of a full Incognito multi-room system with one or two Local Input Modules (LM10) fitted. 2 3 4 5 The local source selection mode will need to be activated to configure the KP10 correctly. This mode is only available when the Mode Switch is set to “AH10” mode. LM10s can only be used in this mode. Please refer to your LM10 Installation Guide for more information.
SOURCE ROTATE FOR LOCAL 1&2 ON THE KEYPAD CONTINUED Continuing to hold both keys down will light LED 3 indicating that Sources 1–6 + Local source 1 mode is available for selection. Continuing to hold both buttons will light LED 4 indicating that Sources 1–6 + Local source 1 + Local source 2 mode is available for selection. Continuing to hold Volume up and Power buttons will light LED 5, to indicate that Off mode is available for selection, and no source will be selected.
Incognito LM10 AUDIO LEVEL ADJUSTMENT The LM10 has independent gain level adjustments for local source inputs. Adjust levels as required using a small trimmer. Turning the gain level pots clockwise increases the audio level and anti -clockwise decreases it. R – Local gain L – Local gain R – Local gain L – Local gain LM10 EU version LM10 CU version The LM10 also has a local infra-red (IR) output allowing for local source equipment to be controlled via an IR1.
