Rear Panel Description

Model CA8125 illustrated: Models CA6160, CA4250 and CA2500 differ only in the number of channels and DIP switch sizes

1. INPUTS CH 1 ... CH n – one 3-pin, 3.5 mm-pitch screw-

terminal connector per amplifier channel. The inputs are

balanced. Connect the audio sources here.

2. INPUT ROUTING – a 2-, 4-, 6- or 8-way DIP switch

depending on model; exception is Model CA2250 which

uses SW4 (CH2 INPUT ROUTING) of the single 8-pole

DIP switch. The factory default setting is with all switch

sections up: in this state each amplifier channel will be fed

by the same-numbered input connector. See page 13

for full description of function. Note that section SW1 on

Models CA2500/4250/6160/8125 has a different purpose.

3. LEVEL – one recessed preset-type control per channel:

adjusts the output level of the channel.

4. SPEAKER OUTPUTS – one 2-pin, 5 mm-pitch screw-

terminal connector per amplifier channel. Connect the

feeds to the loudspeaker systems here. Note that the

same connectors are used for both low impedance and

high impedance (70/100 V-line) operation.

5. 65Hz FILTER – a 2-, 4-, 6- or 8-way DIP switch

depending on model; exception is Model CA2250 which

use SW1 and SW2 (CH1/CH2 65Hz HPF) of the single

8-pole DIP switch. The factory default setting is with all

switches down and filters active. The filter frequency is

65 Hz: frequencies below this will be attenuated.

6. SPEAKER LOAD: HIGH Z/LOW Z - a 2-, 4-, 6- or 8-way

DIP switch depending on model; exception is Model

CA2250 which use SW7 and SW8 (CH1/2 Hi-Z/Lo-Z)

of the single 8-pole DIP switch. In the HIGH Z position

(up), the channel's output stage is configured for driving

70/100 V-line systems. In the LOW Z position (down),

the channels output stage is configured to drive low

impedance speakers (4 or 8 ohms).

7. SPEAKER LOAD: 4Ω/70V / 8Ω/100V – a 2-, 4-, 6- or

CA Series Installation & User Guide v1.0

8-way DIP switch depending on model; exception is

Model CA2250 which uses SW5 and SW6 (CH1/CH2

4Ω/70v or 8Ω/100V) of the single 8-pole DIP switch. The

function of these switches depend on the setting of the

HIGH Z/LOW Z switch [6]. In high impedance mode, the

switches configure the channel's output stage for either

70 V-line (up) or 100 V-line (down) operation. In low

impedance mode, the switches configure the channel's

output stage for either a minimum load of four ohms (up)

or a minimum load of eight ohms (down).

8. AUTO POWER DOWN ON/OFF - set this switch to ON

(down) to enable the amplifier's Automatic Power Down

(APD) function. When enabled, channels will mute after

15 minutes if no input signal is detected; if no signal is

detected for 25 minutes, the channels will enter Standby

Mode. Note that the APD ON/OFF switch uses the first

pole of the INPUT ROUTING DIP switch bank on Models

CA2500, CA4250, CA6160 and CA8125; on Model CA2250 it

uses SW3 of the single 8-pole DIP switch (APD ON/OFF).

9. REMOTE POWER DOWN – a 2-pin, 5 mm-pitch screw-

terminal connector allowing remote control of the

amplifier's Automatic Power Down (APD) function. A

contact closure at this connector will force APD, placing

the amplifier in Standby Mode, resulting in low power

consumption. Note that the REMOTE POWER DOWN

input is always operative, i.e., regardless of the setting

of the AUTO POWER DOWN switch

10. Expansion bay – for retrofitting an optional Dante®

input card, Part Nos.: CDI-CA2 (2 channels),

CDI-CA4 (4 channels) or CDI-CA8 (8 channels).

11. AC input – standard IEC receptacle. Use the AC power

cable supplied with the amplifier.

12. Ventilation exhausts - these should always be

unobstructed when the amplifier is in use.
