The Martin Experience

1 INTRODUCTION

Thank you for purchasing a Martin Audio C115 loudspeaker. This is a

versatile surface-mount loudspeaker designed for high quality music and

speech reproduction in distributed sound systems. It has been carefully

styled to present a discrete, high quality appearance, which will blend

unobtrusively into commercial and architectural environments.

The C115 is available in the following electrical configurations:

• 8 ohm

• 100V line (Europe and Japan)

• 70V line (USA)

Typical applications include retail outlets, bars, hotels and restaurants.

Each C115 is supplied with a unique wall bracket which permits off-axis

adjustment of 40 degrees horizontally and 35 degrees vertically. Additional

hardware is available for corner mounting and for arrays of 2, 3 or 4

speakers to give the C115 exceptional mounting flexibility.

2 UNPACKING

The C115 is packed in pairs complete with wall brackets. Each Martin

C115 is built to the highest standard and thoroughly tested before it leaves

the factory. After unpacking the speakers and brackets, examine them

carefully for any signs of transit damage and inform your dealer if any such

damage is found.

Check that the electrical configuration supplied (8 ohm, 100V line or 70V

line) is the one you require. It is suggested that you retain the original

packaging so that the speakers can be repacked and returned if necessary.

Please note that Martin Audio and its distributors cannot accept

responsibility for damage to any returned product through the use of non-

approved packaging.

3 WALL-BRACKET INSTALLATION

The wall-bracket should be fixed to the wall prior to the installation of the

C115. The bracket has four elongated fixing holes with the fixing positions

shown by small arrowheads in the moulding. The bracket or fixing template

should be held up against the wall in the position required and the four

fixing positions marked on the wall (see template on the outside back

cover). A qualified person such as a building professional of qualified

engineer should determine the method of fixing and type of fixing screw

based on an evaluation of the wall construction.

4 ROTATION FEATURE

The fixing holes in the wall-bracket are elongated to allow the bracket to be

rotated 10 degrees clockwise or anti-clockwise before fully tightening the

fixing screws. This rotation feature may be used to restore horizontal

alignment if the C115 is to be used with a significant downward tilt.

5 NEAR-CORNER MOUNTING

The wall-bracket supplied can be used to mount the C115 close to a corner

if required rather than using the optional dedicated corner mount. Typical

distances of the centre of the bracket from the corner to allow for downward

tilt angles of 0, 10, and 20 degrees are shown below. Each tooth on the

egg shaped-moulding corresponds to a tilt angle of 10 degrees.

Tilt Tooth Distance of centre of

bracket from corner

0˚ 0 57mm

10˚ 1 67mm

20˚ 2 82mm

6 ATTACHING THE SPEAKER TO THE BRACKET

Once the bracket has been fitted to the wall, the speaker can be installed.

The speaker is fixed to the tongue of the wall-bracket by means of an M5

socket cap screw supplied with the bracket. The recess in the rear of the

C115 should be placed over the tongue and the M5 screw inserted upwards

through the hole in the base of the C115 between the connecting terminals

into a threaded insert in the tongue. The speaker can be rotated

horizontally on the tongue about the axis of the "base" screw which should

then be fully tightened when the required horizontal angle has been

determined.

The vertical tilt of the speaker is set by undoing the screw in the end of the

egg-shaped moulding on the bracket that has teeth which allow different

vertical tilt angles to be achieved. Once the desired vertical angle is

reached, fully tighten the "egg" screw.

ENGLISH

It is important that both the "egg" screw and "base" screw are fully tightened

once the final position of the speaker has been set.

7 CONNECTING THE C115

The loudspeaker terminals will accept stripped wires up to 1.5mm2diameter.

The wires should be stripped to approximately 8-10mm. It is important that all

the C115’s in a distributed system are wired in phase i.e. consistent polarity is

maintained throughout. Each C115 is wired so that a positive voltage on the

RED terminal causes forward motion of the speaker cone.

8 TRANSFORMER VERSIONS

The 70V and 100V versions of the C115 have an internally mounted tapped

transformer and a switch, which selects the power delivered to the

loudspeaker. The switch is located at the rear of the enclosure to the right of

the wall bracket when viewed from the rear. The switch is adjusted by means

of a small flat blade screwdriver as follows:

Switch Position (view from rear) Power

Position 1 (fully anti-clockwise) 3.75W

Position 2 7.5W

Position 3 15W

Position 4 (fully clockwise) 30W
