the binding posts. If you have lost the cable 
binding post tool then a large screwdriver will 
also work, but be careful not to overtighten 
the binding posts as they may be damaged.

The RAM1 has two parallel 10 kOhm input 
connectors: a balanced XLR and an unbal-
anced  RCA.  For  longer  cable  connection 
lengths  (>10m  or  >30ft)  a  balanced  line 
connection  is  recommended  as  it  offers 
better  immunity  to  external  interference. 
However,  the  RCA  connection  method 
is  more  commonly  available  and  usually 
works as well for shorter connection lengths 
in  less  electrically  noisy  environments.  Do 
not use both inputs at the same time. Con-
sult  your  Genelec  dealer  for  the  choice  of 
signal cables.

The RAM1 has a provision for remote control-
led switching between “ON” and “STANDBY” 
modes. The “REMOTE  CONTROL”  connec-
tor block has two connector pairs: 1-2 for a 
12 V  DC  trigger  remote  control  and  3-4  for 
an  external  switch  or  relay  type  (contact 
closure) remote control (see Table 2). Do not 
connect two remote controls to the amplifier 
at the same time.

Space requirement for the RAM1 

amplifier

The dual 120 W power amplifiers of a RAM1 
unit generate a large amount of heat when 
used  at  full  power.  To  avoid  overheating, 
ensure that there is good airflow around the 
amplifier and no external heat sources close 
to  it.  We  recommend  installing  the  RAM1 
into  a  well  ventilated  equipment  rack  using 
its dedicated RM1 rack mount kit. 

If the RAM1 amplifier is placed in a cabinet, 
on a shelf or into an equipment rack without 
its dedicated RM1 rack mount kit, there must 
be at least 100 mm (4”) of free space behind, 
150 mm (6”) above and 50 mm (2”) on both 
sides  of  the  amplifier  to  ensure  adequate 
cooling (see figure 8). 

Mounting the RAM1 amplifier to an 

equipment rack

We  recommend  that  you  use  the  Genelec 
RM1  rack  mount  kit  when  installing  the 
RAM1 amplifier in an equipment rack. Make 
sure  that  the  space  above  and  below  the 
RAM1  is  uncluttered  and  there  is  a  space 
of  100  mm  (4”)  or  more  behind  the  ampli-
fier. The space behind the amplifier must be 
well ventilated. If the temperature inside the 
rack  is  likely  to  rise  close  to  RAM1’s  maxi-
mum ambient temperature of 35° C (95° F), 
we  recommend  installing  ventilation  fans  to 
ensure that the thermal protection is not acti-
vated prematurely. 

Attach the RAM1 to the RM1 rack mount with 
two M3 screws provided with the rack mount 
kit. The screws go through the holes on the 
RM1’s shelf plate (see Figure 9 ). Each RM1 
can  take  three  RAM1  units.  Two  blanking 
plates  are  provided  to  cover  empty  spaces 
in  the  rack  if  only  one  or  two  RAM1’s  are 
installed.

Setting the input sensitivity

The input sensitivity of each speaker can be 
made to match that of the decoder or other 
source by use of the input sensitivity control 
on the amplifier’s front panel (see figure 6). 
A small screwdriver is needed for the adjust-
ment.  The  manufacturer  default  setting  for 
this control is -6 dBu (0.389V, fully clockwise) 
which gives SPL of 100 dB @1m with -6 dBu 
input  level.  Note  that  to  get  the  full  output 
level of 110 dB SPL, an input level of +4 dBu 

Figure 6. Front panel of the RAM1 amplifier

Figure 7. Rear panel of the RAM1 amplifier

(1.22V)  is  needed  in  this  setting.  Most  pre-
amplifiers are capable of this output level.

Setting the room response controls

The  acoustic  response  of  the  system  may 
have  to  be  adjusted  to  match  the  acoustic 
environment  and  personal  taste.  See  Table 
3  for  suggested  room  response  control  set-
tings  in  differing  acoustic  environments.  If 
the sound is found subjectively too bright, set
