INSTALLATION
Tools
You will require the following:
·
Small flat bladed screwdriver
·
Screws, fixings and appropriate tools for mounting CLD1-AC on wall etc.
Location
The amplifier should be mounted where:
·
It is in close proximity to the loop.
·
it is protected from drips or sprays of water.
·
it is not vulnerable to mechanical damage.
·
the controls can be accessed during set-up.
·
the cables will not be inadvertently caught or pulled out from the unit.
·
any heat generated during normal operation can escape.
The induction loop itself is a critical to correct system performance, either:
·
Unfold the loop coil and fit vertically inside the front panel of the counter
using the adhesive fixings provided. The top of the loop coil should ideally
be at a height of 800mm above the floor. See diagram in Quick start.

·
To cover a larger area, a perimeter loop using 0.5mm to 1.5mm cross-
section wire or equivalent. Return the feed to the amplifier with a
twisted pair. Refer to 'Designing Induction Loops handbook' for details.
Please consult Ampetronic if you need more advice about the loop design.
Connections
LOOP: Connect the loop cable to the 'LOOP OUTPUT' socket.
1. To open the spring clamp terminal - insert a flat bladed screwdriver into the
small “tab” above the hole. Push gently until hole opens.
2 Insert the wire (remove 7mm of insulation from end).
3. Remove the screwdriver - clamping the wire in place.
INPUTS: Both inputs are 3.5mm two pole (mono) jack sockets. They will not
interface directly to any stereo signal source. Connect inputs as shown in the
connection details.
INPUT 1 Unbalanced electret microphone only.
INPUT 2 Microphone as INPUT 1, or Line level input.
Note: Set the 'INPUT 2
SELECT' switch to the appropriate position for the type of signal source used.
AC POWER: The 'POWER INPUT' socket accepts 100-240V . Connect to a
AC
convenient AC power socket.
