• 

Euroblock output connector

• 

Coupling plate (x2) with necessary screws

• 

Long angle bracket

• 

Front angle bracket (x2)

Rack Mounting

The CA series amplifiers come with rubber feet that enable the amps to be 

placed on a clear surface without an additional installation. However, optional 

rack mounting hardware is also supplied, allowing several models to be housed 

and protected inside an enclosure. Follow these steps to attach the mounting 

hardware. 
A pair of CA units can be mounted side-by-side to occupy a single rack space. 

Attach the coupling plate to the underside of 2 CA units using the included 

screws.    

Attach the front angle brackets to either side of a pair of CA units that have been 

coupled. Alternatively, a single CA unit can be installed in a 19" rack using the 

long angle bracket, or in a half  

19" rack using the short angled brackets.
Attach the angled brackets, by unscrewing the chassis side front screws and 

attach again together with the brackets. 

If your rack has rear rails, attach the rear flat brackets by reusing the screws from 

the chassis.

Mount the CA units into the rack by attaching 4 rack screws through the front 

angle brackets and rack rails. 
Hold one of the rear angle brackets up to the rear rack rails so that it lines up next 

to the rear flat bracket. Do not attach it to the rear rails yet. 
Insert the included shoulder screw through the slot in the rear flat bracket and 

into one of the threaded holes in the rear angle bracket. The screw should allow 

the rear angle bracket to slide forward and back within the flat bracket’s slot. 

Repeat the process for the other rear angle bracket.
Mount the rear angle brackets to the rear rack rails using 4 standard rack screws.
Tighten the shoulder screw if necessary.  
The standard rack screw is M4 x 8mm. 
The CA series amplifiers are convection cooled and primarily use the top surface 

to dissipate heat. For demanding applications, it is recommended to have 

sufficient space (1 RU) above the amplifier to reduce the risk of limiting due to 

overheating.

Table/Wall Mounting

Connect a pair of coupling plates to either side of a CA series amplifier, then 

mount screws through the remaining holes in the plates to secure the unit to a 

wall or table.

Connections

For balanced input connections, use a 3-pole cable (hot, cold, ground) wired to a 

Euroblock connector. Alternatively, RCA cables can be connected for unbalanced 

stereo sources, but the RCA and Euroblock inputs should not be used together on 

the same input. Note that stereo RCA signals will be summed to mono. 

For output signals, connect a 4-pole (2-pole for CA601/1201/2401) Euroblock 

connector to the main output connector. Do NOT connect any terminal to ground. 

Do NOT connect the cold (-) terminals together for common returns. Make sure to 

set the Config switches in the correct position to match your intended use. 

Speaker wire of 14-18 AWG (0.8 to 2.5 mm) is recommended for connections up 

to 50 feet. 

 

Config

The first 2 Config dipswitches allow the output to be configured for 100 V, 70 V, 8 

Ω, or 4 Ω operation. Always use the correct configuration for the speakers being 

driven! The mode of operation configures both the maximum voltage of the 

output and the gain through the device.
The 8 Ω setting should be used for a pair of 16 Ω speakers or a single 8 Ω speaker. 

The 4 Ω setting should be used for 4 x 16 Ω, 2 x 8 Ω, or a single 4 Ω speaker. Use 70 

or 100V setting for Constant Voltage high impedance speaker systems. Make sure 

the sum of the power tapping on the speakers plus margin does not exceed the 

amplifier's maximum power rating.
The 3rd dipswitch engages a high-pass filter at 80 Hz, which should be used on 

all Constant Voltage systems to avoid saturation on the transformer-enabled 

speakers, but can also be used to help maintain clear sound from small speakers 

or bass-heavy audio.

Remote

RJ45 receptacle to connect an optional remote volume control per channel. 

Use a standard cable to connect the CRC-V accessory. Or connect a custom 

potentiometer with the pinout information. Cable length above 305m (1000ft) is 

not recommended. 

Signal Wake-up

If the amps are powered on, but do not receive any input signal (below signal 

present level) for 20 minutes, the system will enter standby mode to save power 

consumption. As soon as a signal is detected at any input, the unit will exit 

standby mode and resume normal function.
